China is no longer taking on the world’s plastic waste, and our oceans could soon be home to more pieces of plastic than fish. The time to act is now.

There are many ways to reduce plastic waste. Banning their use is one of them. A great deal of plastic packaging is, in fact, unnecessary. Yet it also offers benefits in certain areas, such a hygiene and shelf life, making a complete ban rather unrealistic.

Another approach is to avoid plastic in many situations and to practise “plastic fasting”. Still, even that will not work everywhere, especially in the industrial sector. It is therefore essential to find an alternative solution – one that is also reflected in the EU’s plastics strategy: a circular economy.


The European Union’s plastics strategy

The European Union presented its plastics strategy on 16 January 2018. Under the strategy, all plastic packaging must be either reusable or recyclable at low cost by 2030. One of the EU’s goals in its plastics strategy is to stop marine litter. The long-term goal must be to avoid marine plastic waste entirely. However, creating a circular economy and recognising the value of a material that is widely considered to be refuse will be essential to achieving this aim.

The overall EU strategy is based specifically on four basic tenets:

  • manufacturing recyclable products
  • optimising the separation and collection of plastic waste
  • increasing recycling capacities
  • reusing recyclates in production

In doing so, the EU is voicing a commitment – an absolute necessity given the waste and recycling figures.



Unused potential

Every year, the people of Europe produce 25 million tonnes of plastic waste. 
The world produces 78 million tonnes of plastic waste a year.
The world as a whole needs to respond to this global problem. So far, recycling rates have been low around the globe,
ranging from 30% in Europe and 25% in China
to just 9% in the US (plastic waste statistics for 2017).
Much of that waste ends up in landfills or is incinerated, posing a risk to our groundwater and the air.


Projects such as Pacific Garbage Screening are currently trying to develop technologies and methods for collecting waste. The massive quantities of refuse destined for the world’s oceans could be separated using appropriate sorting systems and reused efficiently if it were possible to fish them out of the water at the mouths of rivers – something that would also be in line with the EU’s plastics strategy.


The circular economy in the real world



So how does a circular economy work? Recyclability must be taken into account when designing packaging. That is because the material itself has to be as pure as possible in order to actually be able to use plastic waste or used plastic as a secondary raw material and convert it into recyclates with the quality necessary to manufacture new products, no matter where in the world this process takes place.



Find out what role Sesotec’s expertise can play in the circular economy in the third part of our “Plastic: part of the problem…part of the solution” series. Look forward to part 3 - coming soon.

The production of plastic has increased dramatically around the world in recent decades and currently stands at 200 times the amount manufactured by factories back in 1950. Europe is responsible for one-quarter of the world’s plastic consumption, mainly due to packaging that lands in the rubbish bin after being used for only a short time. Plastic is also used in construction (20%), vehicles (8.6%) and electronics (5.7%).

China and the EU up the pressure

Even today, used plastic is often considered to be refuse and is seen as a problem that can be taken care of by simply throwing it away. In recent years, a large amount of used plastic has been shipped to China, destined for what many believed was a solution. Roughly 51% of the world’s plastic waste, or 7.5 million tonnes, ended up in China in 2017. At the time, China was the world’s largest importer of plastic waste. Transporting waste there by ship, and then loading the ships with new consumer goods for the journey back to their home countries, was long seen as a profitable business model. However, this cycle has since been made more difficult by China’s National Sword initiative. What is the idea behind it?

In January 2018, the Chinese government stopped the import of low-quality plastic waste as part of its National Sword programme. Only plastic waste with a purity level of 99.5% or more is still allowed into the country. China no longer wants to act as a dumping grounds for other countries. The Asian countries that subsequently stepped in at short notice to take on the waste have been overwhelmed and will eventually issue their own bans on imports. As a result, they are not a solution to the current problem, presenting the waste management and recycling industry with a number of challenges. Finding alternatives is an absolute must.  

The EU has also acknowledged the problem. In early 2018, it adopted a plastics strategy, stating that all plastic packaging must be either reusable or recyclable at low cost by 2030.

The strategy poses another challenge for the waste management and recycling industry that ultimately places it in the same position as China’s National Sword initiative: ensuring the utmost purity of plastic waste prior to its recycling and reuse – an essential part of its ability to be employed as a secondary raw material.


Plastic – and no end in sight

The first plastic product hit the market in 1950. At the time, the world
produced around 1.5 million tonnes of plastic every year. In 2017, that figure
stood at roughly 350 million tonnes annually. A total of 8.3 billion tonnes of
plastic were manufactured between 1950 and 2017. 
China is the largest producer of plastic (26%), followed by Europe (20%) and North America (19%). According to estimates from Plastics Europe, plastic production is set
to increase to 1,124 million tonnes.


A floating problem

The world’s oceans are already home to 150 million tonnes of waste. Three-quarters of it is plastic waste, and 1 million tonnes is added to that amount every year. Many living creatures die a painful death as a result. So far, little research has been performed on the effects that plastics in the world’s oceans can have on the health of humans, who are exposed to it through the food chain. But what has been proved is that plastics take 350 to 400 years to decompose.

Packaging material disposed of along the shoreline, residues from rivers and fishing waste, such as leftover nets or ropes, are the main causes of marine pollution and the suffering of many marine organisms.

The long-term goal must be to avoid marine plastic waste entirely. However, creating a circular economy and recognising the value of material that is widely considered to be refuse will be essential to achieving this aim.


Tracking down marine debris

Plastic waste is mainly concentrated in five regions: in the north
Pacific, Indian Ocean, south Pacific, north Atlantic and south Atlantic. In
each region, the waste gathers close to the equator, where various water
currents and temperatures converge. 

The largest patch of floating debris is the Great Pacific Garbage Patch
in the northern Pacific Ocean, with an area of roughly 1.6 million square
kilometres and an estimated 1.8 trillion pieces of plastic.


Purity matters

With plastic consumption and waste constantly on the rise, fast and efficient methods of recycling and reuse at the locations where waste is generated are of the essence. 

A new way of thinking and a new approach are also necessary from a sustainability perspective.

Plastic waste can no longer be seen as rubbish. In times of dwindling fossil resources, it is a valuable commodity. Top-quality recycling material is the key to top-quality reuse.

Taabbel & Co. A/S in North Jutland.

Taabbel processes all types of fish and shellfish into products for caterers at home and abroad. Taabbel‘s mission and goal is to produce food constantly at a high quality standard that complies with applicable food safety regulations, especially the requirements based on HACCP principles. The metal detection system VARICON COMPACT from Sesotec consists of a tunnel metal detector, a conveyor belt and a control unit. In the case of metal detection, the separation takes place by means of a belt stop.


VARICON COMPACT can be easily integrated into existing production lines. It detects various metallic foreign bodies in products and thanks to its high detection performance, it is ideally suited for applications in the food industry.

Effective protection for consumers, machines and image

Sesotec‘s metal detection systems, used to inspect piece goods after packaging, weighing or labelling, protect the products of manufacturers and processors in the food industry from unwanted metal contaminants. The tunnel metal detector detects metal particles contained in products quickly and efficiently. Thus, consumers, machines and the reputation of the company are well protected.

The solution for Taabbel in the fish industry

The two VARICON COMPACT metal detection systems were sold by Fisker Skanderborg A/S to P. Taabbel & Co. A/S in North Jutland. „The solution is extremely hygienic and meets the high demands of the food industry“, was the argument from Fisker´s Sales Manager Flemming Foldager to convince his customer.

For Per Toft, Technical Director of Taabbel, the quality and price of metal detection systems were the most important points. That‘s why he chooses the solution from Sesotec. „All of our frozen fish pro­ducts have passed through Sesotec‘s metal detectors. The operation of the VARICON COMPACT devices is very logical and therefore easy to learn. They fully live up to our expectations“, says Per Toft.

<![CDATA[Metal Detector for the Quality Inspection of Rubber Mats]]> 2019-06-04 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/metal-detector-for-the-quality-inspection-of-rubber-mats https://www.sesotec.com/emea/en/resources/blog/metal-detector-for-the-quality-inspection-of-rubber-mats Case Studies

CY Handee Rubber Mouldings in the north of Malaysia produces rubber mats for a renowned international furniture company and is market leader in Malaysia. To meet the quality requirements that are demanded by the furniture company, CY Handee Rubber Mouldings decided to install a metal detector, and for this purpose they compared and evaluated Sesotec and another supplier.

For final quality inspection CY Handee Rubber Mouldings wanted to inspect large boxes filled with rubber mats before they leave the company. The objective was to ensure that the boxes exclusively contain rubber mats without any metal inclusions. Since the boxes are very big, the performance of the metal detector with respect to scanning sensitivity was of greatest importance because the sensitivity decreases with increasing size of the detector.

Sesotec‘s GLS tunnel metal detector is installed in a conveyor belt and provides highest sensitivity and maximum interference immunity. The GLS tunnel metal detector is used in many industry sectors. It detects all magnetic and non-magnetic metals and due to its extremely short metal-free zone can be easily integrated in every existing conveyor belt.

In addition to the technical reliability of the metal detector it was an advantage for Sesotec that they provided a demonstration system. This demonstration system convinced CY Handee Rubber Mouldings both with its easy installation and its ease of use and operation. The facts that the high scanning sensitivity requirements were fulfilled and that excellent detection results were achieved then resulted in a purchase decision in favour of Sesotec‘s GLS tunnel metal detector.

Technical features surely are important for the choice of a supplier, but a long-term partnership only can be based on excellent additional services, and for CY Handee Rubber Mouldings these were the crucial factors for their decision in favour of Sesotec.

For Sesotec GmbH, one of the leading manufacturers of product inspection and sorting systems for the food industry, the IFFA 2019 trade fair appearance was centered on two important subjects: X-ray technology and services.  

For Sesotec, close cooperation with customers, who are important drivers of innovation and partners on the same level, is the key to the success of X-ray systems. At their trade fair stand Sesotec therefore presented an "X-ray inspection for the future" design study where users had the chance to discuss the requirements, e.g. with respect to construction and design, that an X-ray inspection system in their opinion should meet. Customers who talked with the Sesotec team at the trade fair stand provided feedback from their practical experience and described the features they would like to see or even expect in X-ray systems of the future.  

With respect to innovative services Sesotec at the IFFA presented the new "Lifetime Warranty" service package for X-ray systems. This service package includes a lifetime warranty extension for X-ray tube and detector as well as predictive maintenance. The advantage for users of Sesotec X-ray systems with "Lifetime Warranty" service is that production can be run throughout the complete lifetime of the system with maximum value added and with full cost control. 

The supporting program of the IFFA this year again included the "IFFA Forum" that in technical lectures focused on important industry trends. "Food Safety" was one of the top subjects. Uli Hurzlmeier, X-ray Product Manager of Sesotec, in this context gave a lecture on the subject of "Detection of plastics with dual-energy technology". The resonance of the audience was positive throughout, which clearly indicates that in the meat industry the subject of "Detection of plastics" is gaining more and more importance and that solutions are actively searched.

The supporting program of the IFFA this year again included the "IFFA Forum" that in technical lectures focuses on important industry trends. "Food Safety" was one of the top subjects. Uli Hurzlmeier, X-ray Product Manager of Sesotec GmbH, one of the leading manufacturers of product inspection and sorting systems, in this context gave a lecture on the subject of "Detection of plastics with Dual-Energy technology".

It is a fact that food products more and more often have to be recalled because they are contaminated with foreign particles - among others with plastics. To protect consumers against negative consequences, complete batches of products often must be withdrawn from the market. As an innovative solution approach for the detection of contaminants, especially of plastics, Uli Hurzlmeier presented the possibilities of X-ray inspection with Dual-Energy technology.

Conventional X-ray systems are able to detect contaminants such as metal particles and stones. Plastic and rubber contaminations due to their low density often are not detected. For the detection of plastic contaminations the Dual-Energy method offers an alternative solution.

The Fleischmanufaktur Haspel e.K. with over 25 years of experience in purchasing, processing and selling meat, relies on quality and innovative technology. At the company headquarters in Dombühl, the company employs more than 200 people and give great importance to compliance with national and international quality standards such as the QS seal and IFS. In addition, individual customer requirements are met. Haspel is not only driven about achieving quality standards but also by the good conscience that the goods are free from contaminants.

A wide range of fresh and frozen pork and beef meat as well as meat preparations in various packaging variants from 200 grams to six kilograms and very high product effects require metal detection with top technology. An outgoing goods inspection of up to 130 tons of meat and meat preparations processed every day is necessary.

The conveyor belt system UNICON+ from Sesotec with integrated metal detector INTUITY ensures stability and hygiene in combination with maximum metal detection performance and easy operation. The multi-simultaneous-frequency technology allows Haspel to inspect products from three different packaging lines with the same metal detector. „Fast changing of different programs via external control our own management system represents a very important and useful function for us due to the already mentioned three packaging lines" says Florian Stadelmann, Production Manager of the Haspel Fleischmanufaktur.


In multi-simultaneous-frequency technology, two frequencies between 0 and 900 Kilohertz work in parallel. The selection of the two frequencies that best suit the product takes place during the learning process. Afterwards, INTUITY will simultaneously use these two frequencies to achieve the best metal detection results.

The customer‘s goal is to be able to inspect the most diverse meat products and packaging sizes with the best possible sensitivities. Although Sesotec units are already known, tests were made with devices from different manufacturers to compare the performance of the new multi-simultaneous-frequency technology. INTUITY from Sesotec convinced with highest detection performance and very simple operation. In addition to this come a impeccable and stable operation without rejection faults and the best sensitivity to stainless steel, which lead to the full satisfaction of the customer. The cooperation between Haspel and Sesotec is once again confirmed.

<![CDATA[Advantages and benefits of OPC UA in the plastics industry]]> 2019-05-07 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/advantages-and-benefits-of-opc-ua-in-the-plastics-industry https://www.sesotec.com/emea/en/resources/blog/advantages-and-benefits-of-opc-ua-in-the-plastics-industry Plastics For years now, the world has been talking about “Industry 4.0”. The exchange of data in production plays an important role in making the introduction of Industry 4.0 a success. The open communication protocol OPC Unified Architecture, or OPC UA, is increasingly gaining popularity as a way of promoting data sharing. But what advantages and benefits does using OPC UA offer the plastics industry, for example? 

In the plastics industry, the OPC UA machine communication standard helps to optimise processes from production to service while minimising the loss of time, resources and products (rejects), thereby ensuring top quality and maximum value creation. 

An example of OPC UA communication: metal separator “talks” to mixing and dosing unit

A plastics company that produces caps and lids for the cosmetics industry, for example, may have multiple injection moulding machines in use on the shop floor. To increase plant availability, the company might use metal separators that are located directly between the mixing and dosing unit for the granulate and the material feed of the machine.  

Under certain circumstances, the granulate could contain a small, metallic contaminant that makes its way through the mixing and dosing unit and into the machine by way of the conveyor pipe. The metal separator would detect the tiny metal part and expel it safely, preventing any disruptions to the production process. Because a small amount of the desired material is also expelled during separation, the volume of granulate actually reaching the injection moulding machine may fall short of the expected quantity. 

The OPC UA link allows the metal separator to notify the mixing and dosing unit that a certain amount of material has been expelled. At the same time, it provides information as to the volume that needs to be added back into the system to maintain correct calculation. The result is a smooth manufacturing process that produces perfect caps and lids. 

Without standardised communication thanks to OPC UA, even the slightest deviations in the quality and flow of granulate could lead to the production of faulty parts, such as weak, under-injected lids. Such defective products often remain unnoticed at first and are later packaged for shipment to the customer without further inspection, virtually ensuring complaints. 

Advantages and benefits of OPC UA: optimised plant availability and product quality

By intelligently connecting all of the components involved in production and processing, OPC UA ensures smooth communication in the plastics industry. The exchange of data between metal separators and dosing units, for example, is the key to increasing plant availability and product quality while preventing complaints. 

Bartosch Jauernik, an OPC UA expert at Sesotec, says: “We are confronting the challenges of Industry 4.0 head-on and are actively working on the development of OPC UA standards for our devices. Sesotec is one of the first providers of intelligent metal separators for the plastics industry. Our devices can communicate with each other and with other machines, exchange data and optimise themselves.” 



Bartosch Jauernik is available to answer questions related to OPC UA and provide practical tips on implementation and processes.

<![CDATA[Recycling of Electrical and Electronic Waste at Hennemann Umweltservice]]> 2019-04-30 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/recycling-of-electrical-and-electronic-waste-at-hennemann-umweltservice https://www.sesotec.com/emea/en/resources/blog/recycling-of-electrical-and-electronic-waste-at-hennemann-umweltservice Case Studies

Hennemann Umweltservice Elektronik GmbH is headquartered in Espelkamp in North Rhine-Westphalia. The company‘s scope of services comprises the collection, transport, disassembly, and recycling of waste electrical and electronic equipment including all the necessary project planning, organization and documentation tasks. 

Since the beginning of 2015 the company has been a member of the Drekopf-Group, a family-run medium-sized business that has been operating in the field of proper waste disposal for more than 75 years. With the incorporation of Hennemann Umweltservice GmbH the Drekopf-Group was able to expand its scope of services by WEEE recycling. 

Hennemann Umweltservice Elektronik GmbH processes up to 50,000 tons of electrical and electronic products per year. Its customers come from trade, commerce, municipalities, industry, administration, and the private sector. The company‘s services also include the certified destruction of data media. Material is correspondingly processed in the company’s own recycling lines. „And this is where Sesotec recycling sorting systems are used“, says Eugen Wiebe, branch manager in Espelkamp. 

The WEEE recycling process

First of all, waste electrical and electronic equipment is broken down into individual components in manual disassembly stations, shredders, and by means of manual sorting. This allows the separation of valuable and reusable materials. The use of Sesotec‘s automatic VARISORT WEEE sorting systems made it possible to achieve even higher precision in separation and simultaneously reach higher throughput rates.


The VARISORT WEEE recycling sorting systems are used for the re-sorting of shredded small waste electrical and electronic devices. The objective of the sorting process is to separate the mixture of metals that is contained in the material. In addition to this mixture of metals the shredded small WEEE material also contains about 80% plastics which, after metal removal, can be supplied to the recycling loop. The VARISORT WEEE systems transport the material by means of a conveyor belt to the detection unit, which at Hennemann is equipped with sensors for color and shape recognition as well as for metal detection, alternatively also for stainless steel detection. 

Inverse sorting

For this application Sesotec uses inverse sorting, which allows the reliable separation of about 90% of the plastic parts contained in the electronic waste fraction. Inverse sorting means that objects that do not provide a metal signal are sorted out. In this fraction, a purity of >99% is achieved. This application furthermore has the advantage of reduced compressed-air consumption. Since most of the objects that must be sorted out are flat and of light weight, an air pressure of 3-4 bar is sufficient. With this type of sorting, rolling or heavy metal parts (e.g. screws and bolts) that have a small contact surface also are correctly sorted into the metal fraction. 

Separation of aluminium and printed circuit boards

Another sorting task at Hennemann is solved by means of colour/shape detection. The input material in this case is a mixture of aluminium, copper, and PCBs. This mixture is the result of separation in an eddy-current separator, where the resulting aluminium fraction also contains PCBs and copper. By means of re-sorting with the VARISORT WEEE recycling sorting system these PCB and copper parts can be reliably separated from the aluminium parts. This results in two pure fractions that can be sold separately. 

Flexible sorting system

With the VARISORT WEEE systems Hennemann, if required, is also able to perform cable sorting based on combined metal/shape sorting – a typical application for the WEEE sector.  

The Hennemann team received individual training at Sesotec for the various applications of the VARISORT WEEE systems so that operators are able to adapt corresponding system settings for new sorting tasks themselves. Eugen Wiebe is convinced of the advantages offered by Sesotec‘s solution: „With the possibility of combining various sensors, and with individual program adaptations that can be performed by our employees for sorting tasks with different input materials, we can use these systems with greatest flexibility. For this purpose, Sesotec provided intensive training for our employees, and in this field also offers special training courses at Sesotec‘s location or directly at the customer‘s place.“

The machines from the Xtra series have hardened cutting tools made of high quality steel. This guarantees a long service life even when processing abrasive plastic materials. Metal impurities in sprues can nevertheless cause damage to the cutting chamber. In order to reduce impurities and thereby costs, Wanner was looking for a metal detection solution for the inhouse recycling of plastic sprues. The metal detector should be especially suitable for the Xtra series and easy to sell for Wanner´s sales network.

Cutting unit safe protected

Wanner opted for the plate type metal detector ELCON 250 from Sesotec GmbH, since a successful cooperation between the two companies existes already for a long time. With this metal detector are the cutting tools of the granulator safely protected against damage because ELCON detects all magnetic and non-magnetic metal impurities before even touching the cutting chamber. The used half-wave technique stops the crushing tool when metal detection occur and thus prevents the introduction of metallic impurities into the further manufacturing process. In addition, false rejects caused by vibrations in the crushing of brittle plastic materials and hard sprues are minimised.

Carsten Weidel, Regional Sales Manager at Wanner: „What we particularly appreciate about Sesotec is their support on site and the precise implementation of our specifications from Sesotec´s development department. Our customers who use Xtra granulators benefit from the metal detection solution by reducing costs related to machine repair or production stops.“

Sesotec Canada Ltd. is a subsidiary of Sesotec GmbH, a manufacturer of metal detectors, x-ray inspection systems and sorting systems based in Germany. For over four years, Sesotec Canada was based in Cambridge, some 90 km west of Toronto. As of 1 April, it moved from Cambridge to Guelph.

Sesotec Canada is expanding rapidly and the premises available in Cambridge became too small to cope. For this reason the company made the decision to move to Guelph, some 75 km south-west of Toronto.

Download White Paper



As a plastics processor, you know how important the utilisation and uptime of expensive equipment such as injection moulding machines, extruders and blow moulders can be for your company. Avoiding unscheduled downtime due to issues such as metal contamination in granulates is an absolute must. That is why metal detectors are an important part of production lines in the plastics industry today. They help prevent damage and increase the service life of machinery. What is more, greater machine uptime also increases the productivity of the entire line.

The decision to purchase specific metal detectors for moulding machines, extruders and blow moulders is usually based on criteria such as detection accuracy and price, both of which should indeed be taken into consideration. However, two other factors usually do not receive enough attention in the decision-making process: how easy is it to install the metal detector in the production line – and how easy is it for your staff to operate the device?

In our white paper, we will take a closer look at these two factors and show you why you should take them into account when making your decisions. We will also provide you with a checklist that you can use to check whether a metal detector is both easy to install and easy to operate.

A design study on the RAYCON D+ product inspection system and the VARICON+ metal detection system, featuring the INTUITY metal detector, will be showcased at the trade fair. In addition, Sesotec will present the new Lifetime Warranty service package for X-ray machines at its stand at IFFA.

Customer co-creation

Product inspection systems which work with X-ray technology are already widely used in the meat industry. For Sesotec, the key to the success of X-ray systems is close cooperation with customers, who are important drivers of innovation and equal partners. Sesotec will therefore be exhibiting a design study entitled “X-ray inspection for the future” at its stand, where users can discuss what they expect from an X-ray inspection device in terms of its construction and other factors. 

Uli Hurzlmeier, product manager for X-rays at Sesotec: “The most important thing is to understand customers and offer them the services they need. With X-rays, that means not only the accuracy of detection, but also the kind of contaminant the user is looking for and the construction of the devices.” Findings of plastic contamination in meat products have therefore led Sesotec to develop the Dual Energy technological solution in cooperation with its customers.  

At IFFA, Sesotec will present the VARICON+ metal detection system, which is equipped with the INTUITY detection coil and achieves up to 50% higher scanning sensitivity than other systems on the market thanks to multi-simultaneous frequency technology. If used to help inspect outgoing goods, it can ensure that packaged meat and sausage products are free of metal contaminants.

Therefore, their mission is to grow step by step together with their suppliers and to achieve the satisfaction of their customers for whom health and
food safety have priority. Sesotec with its RAYCON X-Ray inspection system contributes to the improvement of food purity.

In this case the concrete detection requirements were particularly high and at the same time it was not allowed to change the dimensions of the inspected tuna blocks. This could be met thanks to the flexible configuration of the X-Ray inspection system in a version with 80 KV X-ray source. The customer can now inspect his standard blocks and benefits from highest detection accuracy – no matter whether the contaminants are metals, stones, glass or plastics whose specific density differs from the density of tuna.



“Our requirements for the detection of contaminations were very high but the constant reliability that the RAYCON system demonstrated in the tests compared to competitor systems made the decision easy for us,“ says the Production Manager.

20,000 tons of virgin PET is imported to New Zealand annually. New Zealand government’s Waste Minimization Fund supports the project to reduce that environmental harm. A grant enables the parent company Flight Group Ltd. to open New Zealand’s first PET recycling plant in Wellington and spend NZ$ 12 million (US$ 8.8 million) on a full upgrade at its facility including a wash plant for PET bottles.

Flight Group was established in 1907 and initially made leather luggage. It is still privately held by members of the original Osborne family owners. Flight moved into plastic production in the 1970s. It also has PET product manufacturing plants in Adelaide, Australia, and Romsey, England.

Keith Smith, CEO of Flight Plastics Ltd in Wellington said the wash plant and other work at the facility enables Flight Plastic to produce thermoformed packaging from recycled PET bottles. The company installed extrusion equipment to use recycled PET flakes starting in 2014, using imported flake to prove the process and establish a customer base.

They had very encouraging results, so the next step was to install their own wash plant. Flight Plastic has the capacity to recycle 6,000 metric tons of PET a year. It gets feedstock from curbside collections around the nation, which collect about 8,000 tons annually.

Sorting bottles and flakes

As a part of the investment in a wash plant, Flight Plastics installed a multi-sensor sorting line including two bottle sorters and a flake sorter. These three systems secure the outputquality as well as a continuous supply of PET flakes to the production line.

After the upstream process steps such as bale breaking the bottles are feed to Sesotec‘s VARISORT MN multi-sensor sorting system. This system was installed for the separation of PET bottles from other polymers (near infrared sensor N) as well as metals (metal sensor M). Flight Plastics also decided to install a further VARISORT CN. This second VARISORT is equipped with colour sensors C and near infrared sensor N for material identification and sorts as well as cleans the PET bottles into a transparent clear and a coloured fraction.

Those sorted bottles are feed into a cutting mill where they are cut to the desired flake size and passed through a washing and drying process. In the next step Sesotec‘s FLAKE PURIFIER multi-sensor-sorting-system is used for a final cleaning of the PET flakes. Here the remaining off-colours, wrong polymers and small sized metal pieces will be removed. This multi-sensor configuration equipped with a high resolution out-blast system allows highest possible sorting efficiency combined with lowest possible material loss rates. Depending on the application the three sensors can be used individually or in combination.

Sesotec‘s FLAKE PURIFIER multi-sensor-sorting-system used for a final cleaning of PET flakes

Flight Plastics director Derek Lander said in a statement: „The opening of the wash and sorting line was a milestone for Flight and its customers. Five years ago, we assessed the economic and environmental costs and benefits of introducing such a plant in New Zealand. The business case was predicated on the wash and sorting line being part of an integrated solution to use recycled PET flake in onsite production. CEO Keith Smith added: “Offshore recycling options are getting fewer, meaning countries need to find solutions for their own waste.“ In regards to the cooperation and the performance of the Sesotec machines Smith emphasized: “We are finding the Sesotec machines to be very reliable and user-friendly. In particular we have been impressed with the quality of service and support from the Singapore-based team.”

X-PACK is a Tunisian company which has developed more than 100 references of plastic packaging for the last 10 years. One major business is the processing of high-density polyethylene (HDPE) to produce reliable closures for the packaging industry.

With a big investment in two new injection moulding machines for 150 tons and a material consumption of 18 kg/hr, X-PACK was looking to grow in the market. To be able to do that, the machines have to run at their maximum production last and any production stop affects the productivity and causes huge loss.

Mohamed Amine ABID, Director of X-PACK, says: „We had some production breakdown in the past due to a metal contamination and we did not know where it came from, apparently was mixed in the raw material. After that we decided to protect the hot runner system to avoid a major disaster“.

Two PROTECTOR 40 PRIMUS+, to direct installation as Last Chance Control were the solution for this customer´s problem.

Small metal particles in the plastic melting process often result in costly breakdowns of injection moulders, extruders and blow moulders. The quantity of such metal contaminants increases throughout the processing of regranulates and grinding stock. As a result, clogged nozzles, filters and hot channel systems can lead to production downtime.

The metal separator PROTECTOR is installed directly over the feeder of an injection moulder, an extruder or a blow moulder. It detects all magnetic and non-magnetic metal contaminants (steel, stainless steel, aluminium, etc.) – even when they are enclosed in the product. Metal contaminants are rejected via the “Quick-Valve” separation unit. Metal separators protect the processing machines, prevent malfunctions and thus increase the running time.

The business of Sesotec´s reference customer Khao Shong Group Co.,Ltd. is the coffee blending. Over the years, developed Khao Shong the perfect manufacture process to ensure the optimal flavour of the coffee.

Committed to nature and to the efficient use of resources this customer also strives to achieve highest quality. He thus was able to establish himself on the market and to win the confidence of various OEM customers for whom he produces today.

In the production of coffee mix 3in1 (instant coffee, milk powder and sugar) broken metal particles from processing machines might contaminate the product. And if this coffee mix – as is the case with this customer – is packed in metallized packs it is difficult to detect such metal particles with conventional methods. Therefore, this company was looking for alternative methods for contaminant detection.

The RAYCON X-Ray inspection system from Sesotec is able to detect even smallest metal particles in metallized packs and to sort out contaminated products. Faulty activations are systematically avoided. It is quite easy to make such statements, but Sesotec in an extensive test run at the customer's plant also provided proof of the system's performance.

Says Chana Chiralerspong, Managing Director from Khao Shong Group Co.,Ltd.: "Sesotec's X-Ray technology at present is the best technology to meet the high demands of our quality management. And the experience we have in the meantime made with Sesotec's customer service further confirmed our decision for the RAYCON system."

The beginnings of our reference customer can be traced back to the early 17th century. After a rapid rise in the thirtie s the company was completely destroyed in the years of war, what however, could not keep our customer from pursuing his dream.

What has once started as a small bakery has until today grown into a medium-size family owned company that produces noodles in various forms, sauces and several ready-made products.

In this big industrial company on an area of more than 20.000 sq m about 150 employees are producing products of perfect quality under highest technical and hygienic standards. This company just outside Munich required a metal detector with a focus primarily in detection. In the inquiry from Bernbacher, quality assurance was the most important factor. According to the customer´s description a system should be used to help with noodle filling at the end of a production line. Furthermore, the desired sensitivities that should be reached already were defined and were the incentive for the upcoming test series in the company.

The tests were performed with pasta noodles in free fall, using a P-SCAN RS 170 metal detector. For this application the closed metal detector with round aperture of the P-SCAN Series was exactly the right solution. This system can be perfectly matched to customer specific requirements and can be easily integrated in almost all types of standard pipelines. Only a few tests were necessary because right from the start the results were quite clear. The customer´s requirements concerning the desired scanning sensitivities could be exceeded by far and the reference customer also was highly satisfied with clear and hygienic design.

In addition to all the technical criteria and the positive results, the excellent service and the perfect project handling also were decisive for the decision for a continuing cooperation with Sesotec.

One of the world's leading medical technology companies produces and sells an extensive range of medical supplies, laboratory and diagnostic equipment for health care facilities, life science institutes, and clinical laboratories. In the fi eld of injection and infusion technology the company is regarded as an innovation leader.

The company attaches particular importance to highest quality. Development, production, and delivery of products and services are subject to a continuous process of improvement. For this purpose processes are analysed to determine where and how effi ciency and effectiveness can be increased.

Task: Protection of injection moulding tools and quality assurance of plastic products

For the production of plastic parts by way of injection moulding the medical technology company uses both new granulate and regrind, which may both be contaminated with foreign bodies such as metal particles. In the past this often complicated the injection moulding process because such metal particles resulted in clogging of individual cavities in injection moulding tools, and tools frequently had to be cleaned. This caused expensive production downtimes of injection moulding machines, quality defects of plastic products, and a reduced output.

Looking for a solution for these production problems the company came across Sesotec metal separators. Using metal separators is the most reliable method for the removal of metallic particles and thus for the protection of injection moulding machines and for quality assurance of plastic products.

Solution: PROTECTOR reliably removes metallic contaminants from the processing material

After thorough tests the medical technology company now uses Sesotec PROTECTOR metal separators for the inspection and cleaning of granulate (new material and regrind). Metal separators of the PROTECTOR series are installed directly above the material inlet of injection moulding machines, where they reliably remove metallic contaminations from the slowly descending material column. Apart from outstanding properties such as high sensitivity and space-saving, compact design, the metal separators of the PROTECTOR series especially are characterised by the "Quick-Valve" reject unit. When a metal particle is detected a pneumatically controlled piston in this reject unit moves into its reject position, and the rejected material is completely sucked off into a collecting container by means of a Venturi nozzle. The piston then moves back to its pass-through position again. Only a minimum of good material is lost in this process, and clogging is impossible.

The medical technology company is highly satisfied with the Sesotec PROTECTOR metal separators: "Since the installation of these metal separators the operating time of our injection moulding machines has considerably improved, because disturbing metal contaminations are no longer an issue in the production process.“

At the Fakuma 2018 trade fair in Friedrichshafen from 16 to 20 October, Sesotec GmbH in hall B1, stand 1302, especially for the target groups of injection moulding companies and system integrators focuses on metal separators that can be networked in the production environment. The OPC UA (Open Platform Communications Unified Architecture) machine communication standard contributes to the optimisation of processes in the plastics industry, from production through to service, and to the minimisation of time and product losses, and it thus guarantees highest quality and maximum value creation.

 

What is OPC UA?

Industrial communication through OPC UA provides the required network mechanisms for data exchange between machine components. In the production process this ensures communication that guarantees a smooth production flow and initiates countermeasures in case of errors. Efficient industrial networks and properly functioning automation only can be realised on the basis of communication standards such as OPC UA, because such standards ensure a high level of openness and flexibility. 




What is the benefit of OPC UA for injection moulding companies and system integrators?

If in the processes of the plastics industry processing machines such as e.g. injection moulding machines are networked with peripheral machines, e.g. dosing units and metal separators, it can be ensured that the dosing unit feeds sufficient material if the metal detector detects a metal contamination and triggers a reject process. The benefit of OPC UA for injection moulding companies and system integrators is that product quality can be guaranteed because underinjection of produced plastic parts is avoided. OPC UA furthermore improves and simplifies service, e.g. maintenance measures. Machine parameters can be evaluated on cloud basis and are thus available for service engineers in real time.

At the Fakuma 2018 Sesotec also presents proven metal separators for the plastics industry which prevent metal contaminations from reaching plastics processing machines and thus protect tools against clogging and damage. Furthermore, Sesotec also presents the new service packages that ensure best possible preparation in case of malfunctions. 

At the trade fair stand experts of the Sorting Recycling Division shall be pleased to answer any questions concerning the latest technologies for plastics sorting.

Often on his drive into the office, Huer CEO Ryan Storey asks himself a simple question: "How do I know the innovative products we will make today are being produced and packaged as safely as possible?"

  Our large national customers expect us to have the highest safety standards, so do regulators, so do the children and adults who enjoy the products we process,“ Ryan says. “And no one expects more from us than we do of ourselves.“ Ryan, a former lawyer, clearly understands the potential risks to both consumers and Huer Foods if products are contaminated.

As one of Canada‘s leading confectionery packagers and distributors, Huer Foods has been at the forefront since 1986 with its commitment to identifying and using the latest in proven technologies designed to keep manufactured and packaged products like theirs as safe as possible.

It’s no small task. Subject to random audits and some tough regulatory demands, Huer delivers its own products and packages those of others in all significant channels including grocery, drug, convenience, discount and specialty shops. With offices near Montreal and Vancouver, its reach is nationwide. Certainly, its wide array of products were already safe. But that wasn’t enough for Ryan and his colleagues. “They had to be even safer, and we wanted to find the most advanced tools available to achieve that goal.”


Raising the Safety Bar

Improving safety is the right thing to do. It’s also good for business. Ryan recognized the duality here that eluded his competitors. “We wanted to have a competitive advantage,” he recalls. “I don’t believe all of my competitors use metal detectors.” Leveraging the technology would be a strong selling point in the crowded marketplace. “We saw that it would provide more confidence to our customers and could set us apart from the rest of the pack.”

As part of Huer’s continuous improvement process, Ryan helped to launch a search committee. It began to hit the most important trade shows to kick the tires on some products – and put sales representatives through their paces with tough questions and their ideas on how to solve real-world scenarios. After making the rounds at several packaging shows, Ryan and the search team were struck by the sheer number of companies that said they were in the food production metal detection business. “I was overwhelmed,” he remembers. “There were lots to choose from.” Of course, having too many choices is a nice problem to have. Still, the sheer data to pore over and claims to vet can be a little daunting.

Still, the sheer data to pore over and claims to vet can be a little daunting.

The Huer team knew the kind of solution they wanted; they just weren’t sure they could find it. “We were after something that was of demonstrably high quality, that was easy to learn and use, and boasted cutting-edge technology,” he says. After an extensive search, the Huer team found several firms that fell within the same price range – but Sesotec’s products stood out in terms of quality.


What did Huer see in Sesotec he didn’t find elsewhere?

“It was a clean looking machine,” he explained. It had good visual appeal but its German construction also showed it was very robust. The “heart and soul” of the product is made in Germany, with the conveyor system designed and manufactured in the United States.

Frankly, another selling point was that the product was made by a company whose focus was metal and x-ray detection and nothing else. As Ryan said Sesotec knows their business exceptionally well. Huer selected Sesotec’s C-Scan GHF. This leading edge metal detector boasts high performance detection of magnetic and non-magnetic metal contaminants, an intuitive touch screen set up, USB capability, and as standard HML multi-frequency technology.


Simple Implementation

Setting up the Sesotec equipment was easy. “We got it in the morning, and had it up and running about two hours later,” he explains. Because some of its products – including licorice and gummy candies – require different sensitivity settings Huer‘s production manager went through a spate of synchronicity tests and running products through the system at least eight times to make sure the product adjustments were correct. A small piece of test metal is run through the system every day.„And every day the Sesotec system catches it“, Ryan said with every bit of confidence. A Sesotec tech also helped set up the system. Subsequent training requirements were minimal. In addition, the machine is largely insensitive to vibration and, because it has no dirt-collecting edges, easy to clean.


An Immediate Safety Benefit

When the C-Scan GHF detects metal, a signal is sent to a rejection unit, an alarm or to a process controller to initiate a remedial action. Huer’s salespeople also appreciate Sesotec. “We always focus on it during a presentation,” Ryan says. “We’re in a business, when it is not always easy to differentiate yourself from the others in an obvious way. This is one effective way to do just that.”


A Look Ahead: The Power of Confidence

The partnership with Sesotec is, in part, one of the factors giving Huer the confidence to continue to build private label opportunities with partners and further expand their own brand. “Our retail customers like to partner with Huer because they want to partner with a company that is committed to making the necessary investments in equipment and food safety certification to ensure their brand investment is secure; therefore we must continue to produce everything in a safe and effective manner to grow our partnerships,” Ryan stresses.

 

Doing the Right Thing

At Huer, safety isn‘t an option it‘s a required investment as Ryan points out. No business wants a recall, so an ounce of prevention is clearly worth it. It is about developing long-term relationships and giving partners – new and old – an even stronger sense of confidence when they work with Huer.

<![CDATA[Glass Sorting with Sesotec Sorting Systems at Schirmbeck Glasrecycling GmbH]]> 2018-08-07 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/glass-sorting-with-sesotec-sorting-systems-at-schirmbeck-glasrecycling-gmbh https://www.sesotec.com/emea/en/resources/blog/glass-sorting-with-sesotec-sorting-systems-at-schirmbeck-glasrecycling-gmbh Case Studies

In November 1996 a new combined recycling line for hollow and flat glass cullet was put into operation, processing hollow and flat glass from the regions of South Germany and Switzerland. Already one year later another recycling plant started operations in Kraubath an der Mur (Austria). In March 2007 the plants in Schierling and Kraubath were extended with two additional lines for hollow glass processing.

The branch in Immendingen (Baden Württemberg) that was started in August 2009 is used for the more efficient handling of transport volumes from nearby areas and from Switzerland.

Today the company operates three glass recycling plants in Schierling, Kraubath, and Immendingen. With more than 200 employees and a fleet of approx. 85 commercial vehicles the company every year recycles approx. 400,000 tons of glass (flat glass and hollow glass).

For many years Schirmbeck has been using machines and systems made by Sesotec (formerly S+S) in the plant that was planned by KRS Recycling Systems GmbH. At the Schierling plant glass sorting initially was performed with Sesotec SPEKTRUM systems.

At the IFAT 2014 trade fair the new K9 glass sorting system was presented for the first time, and today Schirmbeck Glasrecycling GmbH uses the K9 Basic and K9 Flash system versions for the sorting of waste glass in the hollow glass line.

The K9 systems are used for the colour separation of cullet starting from a grain size of five millimetres. They improve the quality in the recycling of fine, hollow, and flat glass and allow high throughput capacities.

At the Schierling plant the waste glass from the hollow glass line is sorted with three K9 glass sorting systems. One K9 FLASH system and two K9 BASIC systems are installed in a cascaded arrangement. K9 FLASH separates CSP (ceramics, stones, porcelain), and in the second stage one K9 Basic also performs CSP separation. In the last stage the second K9 Basic is used for colour separation.

The finished material is supplied to the glass-producing industry again. Material that has been sorted out is properly disposed of by external waste disposal companies.

MultiPet GmbH was founded in the year 2001 and started production with a new PET recycling plant. Today the company processes up to 35,000 tons of PET waste every year. The Multiport GmbH sister company also is located in Bernburg. Multiport processes up to 38,500 tons of HDPE and PP waste and produces customerspecific regranulates. The two plants in Bernburg thus have a total capacity of more than 70,000 tons per year. The two companies in Bernburg presently have more than 150 employees.

Right from the start recycling sorting systems of Sesotec were used to separate colours and metals from PET flake flows in the PET recycling plant. With a volume of Euro 1.2 million MultiPet GmbH specifically invested in the optimisation of existing plant components with new recycling sorting systems. The existing sorting stage was supplemented with an additional stage, which in addition to colours and metals also allows the reliable separation of unwanted plastics.

For this purpose Sesotec supplied two FLAKE PURIFIER multi-sensor sorting systems together with suitable installation and material conveying components. Equipped with multi-spectral sensors for the separation of foreign polymers and true-colour sensors for the removal of wrong colours, the sorting systems provide highest qualities in the end product with a minimum loss of good material. These positive quality changes with respect to the specifications for recycled flakes perfectly match the increased quality demands of the customers
of MultiPet GmbH.

Mah Sing Plastics Industries Sdn Bhd (MSPI), one of the largest high-tech plastic manufacturers in Malaysia, has a major local market share and is recognized for its trustworthiness and reliability. They supply local and international businesses with a wide range of plastic products such as plastic pallets and plastic containers. MSPI wanted to inspect raw materials such as Polyethylene (PE) or Polypropylene (PP) before entering the manufacturing process to assure product security. Therefore, MSPI was commisioning JS Analytical to offer a system for separating any metal contamination from those raw materials. 

JS Analytical, part of the Osnab Group from Malaysia, is a solution provider of metrology, analytical and detection equipment serving various industries. They are representing Sesotec metal detectors and separators in Malaysia. Through outstanding personalized professional customer service, they propagate the benefits of these technologies and provide the needed equipment to satisfy their customers. During a visit, a technician from JS Analytical set-up a RAPID VARIO-FS metal separator from Sesotec and gave a live testing showcase on how the unit could improve MSPI’s raw materials´ quality without causing any production stop.

Sometimes there are cases where small metallic impurities enter the production process and may end up damaging the processing machine. To repare the machine, the factory will have to shut-down their work operation for reparation which means a huge loss in production especially if their line operates 24 hours a day.  

The RAPID VARIO-FS from Sesotec is a metal separator for free fall applications. It detects all magnetic and non magnetic metal contaminations (steel, stainless steel, aluminium) – even when enclosed in the product. Metal contaminations are rejected through the “Quick Flap” reject unit, with minimum loss of good material. 

In the test made for MSPI, the RAPID VARIO-FS showed a 100% result detecting and separating metallic parts mixed into the inspected plastic resins.

Trade visitors to a large extent came from the intended target group and showed great interest in the machines presented at the trade fair, the FLAKE PURIFIER+ multi-sensor sorting system for plastics recycling, and the new SPEKTRUM SCOPE glass sorting system.

Sesotec and KRS used the IFAT trade fair to meet many of their customers and to provide information about product innovations, and also in 2018 were able to again welcome many visitors from at home and abroad at the trade fair stand. The further development of the FLAKE PURIFIER+ multi-sensor sorting system as well as the new SPEKTRUM SCOPE glass sorter obviously were well received by customers.

Says Michael Perl, head of BU Sorting Recycling at Sesotec, summarizing the IFAT: "The fact that plastics recyclers showed such great interest at our trade fair stand also may be due to the current situation that it is no longer allowed to export unsorted plastic waste to China, and to the statements of the European Commission concerning plastics and their disposal and recycling. Our partner company KRS Recycling Systems GmbH, which for the first time presented the new SPEKTRUM SCOPE glass sorting system to trade visitors at our Sesotec stand, also gave a highly positive feedback. The machines and systems we presented at the fair, and the sorting concept solutions of our team, resulted in interesting and promising talks that reflect an overall positive atmosphere with respect to the business situation and positive future prospects for the year 2019."  

Sesotec is a regular exhibitor at the IFAT in Munich because the IFAT trade fair is a very important communication platform for the dialog with customers. For Sesotec the trade fair furthermore is an important cornerstone for brand communication under the slogan "Purity matters".

The Mexican company organises the collection of plastic bottles through its own national network of collection centres.  Pressed into bales the plastic bottles arrive at the GREEN Mind plant, where they are first singularised, and in the next step the labels are removed. After pre-washing the plastic bottles then are separated into unmixed fractions, and this stage in the recycling process is where Sesotec's VARISORT multi-sensor sorting systems are used. These systems are equipped with sensors for colour and shape detection, and with sensors for the differentiation of plastic types.

Subsequent shredding of these sorted PET bottles then is followed by washing, drying, and screening processes. The PET flakes then undergo fine sorting with the help of Sesotec FLAKE PURIFIER sorting systems. The FLAKE PURIFIER systems at this stage separate coloured flakes, metals, and foreign plastic parts from the transparent PET flakes.

Contact between Sesotec USA and GREEN Mind was established through the Mexican distribution partner Innovateck®. GREEN Mind has been using Sesotec sorting systems since 2012. The Mexican company first invested in a flake processing line with a total of four recycling sorting systems. The excellent quality of the end products and the continuously increasing recycling rates in the year 2015 then were the reasons for GREEN Mind to build an additional sorting line and to integrate another five Sesotec recycling sorting systems in this line. For the purpose of machine protection GREEN Mind also uses seven Sesotec metal detectors. All this demonstrates how Sesotec's product portfolio ideally supports the complete recycling process.

Confirms plant manager Saúl Solaeche: "We are convinced by the quality of the sorting results, and we are highly satisfied with the maintenance and service of our Sesotec systems. We shall recommend Sesotec in every respect."

<![CDATA[New Sesotec Website]]> 2018-06-06 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/new-sesotec-website https://www.sesotec.com/emea/en/resources/blog/new-sesotec-website Company

For Sesotec, one of the leading manufacturers of machines and systems for contaminant detection and material sorting, the ambition to achieve more customer and market orientation is a main driving force in corporate strategy decisions and in branding. In this context the corporate website is the most important information, communication and interaction instrument, and was therefore created completely anew with respect to design, structure and content. 

New structure in a new design

For the uniformity of content and brand design a new structure was developed that is based on the interests and usage behaviour of customers. "Attractive pictures should immediately fascinate website visitors, because a user only remains on the website if the first impression really fits", explains Benjamin Manzenberger, Senior Online Marketing Manager at Sesotec's  corporate headquarters in Schönberg and responsible for the relaunch. On the homepage the visitor can directly reach the "Industries" and "Products" pages, and can use a "Burger" navigation that allows quick orientation and leads to various sub-items. The new Sesotec website features Responsive Design, which means its flexibility ensures the same user friendliness on the computer desktop, tablet and smartphone, and the full content is quickly available for the visitor.




Informative content attractively presented

"The new website contains both short informative texts and also detailed articles. For example, we explain to our visitors where Sesotec systems can be used in their industries", explains Manzenberger. Many pictures and graphics are used to illustrate and supplement the texts. Links are used to inform the visitor about contents that also may be interesting for him.  

High-quality contents in multimedia formats, especially in the form of videos, whitepapers and case studies, with practical orientation make it possible for the customer to experience Sesotec competence in the complete value creation chain as a reference for his specific project and as a basis for his individual solution.

"Instead of only reading theoretical contents on the website, customers can really experience how contaminant management actually works in real operational practice", says Manzenberger. Case studies demonstrate which product inspection systems are available and where these can be used. Visitors furthermore have many possibilities to contact Sesotec, e.g. to reach the Service Center, or to arrange a visit date.

At the Anuga FoodTec, the world's leading trade fair for the food and beverage industry in Cologne, Sesotec GmbH presented intelligent, long-lived and robust contaminant inspection and sorting systems for the industry. 

As trade fair highlight Sesotec GmbH presented the completely new developed RAYCON D+
X-ray inspection system to trade visitors. With the intelligent power management software of the RAYCON D+ system Sesotec sets new standards not only with respect to detection accuracy, application flexibility, and ease of operation, but also with respect to the long service life of the X-ray tube. The automatic adaptation of the X-ray power to the product, and the Edge Filter that automatically detects the edge e.g. of packagings, both minimise the frequency of false rejects and of wasted products.   

In addition to the RAYCON D+ Sesotec at the Anuga FoodTec 2018 also presented the INTUITY metal detector that is excellently suited for use in the food industry, and the attractively priced RAYCON EX1 entry-level X-ray inspection system. The new QUASAR optical sorting system that was developed especially for the requirements in the quality inspection of bulk materials also was shown at the trade fair. 

"We really are pleased that our intelligent and long-lived contaminant inspection systems and sorting systems that contribute to the optimisation of value creation by minimising losses of time and products made such an excellent impression on trade visitors at the Anuga FoodTec", summarises Sesotec EMEA sales manager Oliver Uhrmann.

At the IFAT 2018 trade fair that will be held in Munich from 14 to 18 May, Sesotec GmbH in hall B5, stand 415/514, will present the FLAKE PURIFIER+ multi-sensor sorting system that now as standard is equipped with a 3.2mm nozzle and valve grid, allows a higher throughput capacity, and is easy to operate with the "SesoDesk" operating software. As co-exhibitor Sesotec's partner company KRS Recycling Systems GmbH will be present at the IFAT trade fair stand with the new SPEKTRUM SCOPE glass sorting system. The SPEKTRUM SCOPE among others features a new NIR (near infrared) sensor unit.

The modified FLAKE PURIFIER+ multi-sensor sorting system in addition to optimised material infeeding now also features a valve unit with doubled number of nozzles, which ensures higher precision in contaminant separation and a reduced loss of good material. Furthermore, the dust-proof design and the resort track that can be integrated in the FLAKE PURIFIER+ also increase efficiency in the recycling process, especially in cases with highly contaminated input material.  

Michael Perl, head of BU Sorting Recycling at Sesotec, says about the FLAKE PURIFIER+: "For the modification of the FLAKE PURIFIER multi-sensor sorting system into the new-generation FLAKE PURIFIER+ the wishes of our customers for increased throughput capacities with minimised loss of good material, and thus an overall increase of value creation, were the decisive factors."

Together with KRS Recycling Systems, Sesotec for the first time present the SPEKTRUM SCOPE glass sorter that is equipped with the new Sesotec NIR sensor unit. With this sensor unit, for example, transparent plastics of the same colour can be differentiated in a flow of white cullet.   Special glass types, among others borosilicate glass, also can be reliably detected. To allow even higher throughput capacities and more flexible plant planning, the working width of the SPEKTRUM series is extended to 1563 mm with the SPEKTRUM SCOPE.

CUSTOMER NUTRADRIED CREATIONS

Nutradried Creations is a Blaine, Washington-based leader that uses state-of-the-art technology to create shelf stable, healthy snacks derived from natural, whole foods. As a company, it boasts a track record that demonstrates it is about more than turning a profit.

 Nutradried Creations has a compelling, simple mission statement: Nutradried Creations’ purpose and mission is to create a Triple Bottom Line – impacting people’s lives and bringing profit to shareholders – through social business by selling environmentally and socially responsible products that will ensure that the customer receives the best nutritional products possible, through the innovative use of our patented process and strategic relationships.

For example, it partners with organizations like Agros International, a Seattle-based nonprofit that assists poor, rural farmers in purchasing their own land through low-interest or interest-free loans. This helps these farmers break out of their generational poverty cycle. By only purchasing ethical ingredients that are fairly traded, Nutradried also partners with its customer to provide a fair wage for a beautiful product. This helps to enable farmers to provide food, clothing, shelter, and an education for their children. The achievements are impressive. With Agros, Nutradried Creations helped develop 42 villages, aiding 24,000 farmers and fostering generational change. It is now doing similar work in Ethiopia by supporting dairies that feed orphanages and provide economic opportunity for their local communities. To help achieve these and other goals, the company needs vendors it can trust to help it on the operation and processing side.


THE HACCP CHALLENGE

In addition to new customer expectations, Nutradried Creations must also comply with a higher compliance bar raised by the Food and Drug Administration (FDA) in the past several years. Perhaps the most significant are the much tougher Hazard Analysis and Critical Control Points (HACCP) requirements. When an inspector comes calling at your food processing facility, they expect to find strong evidence that you have completed a hazard analysis, and have a plan that includes, identified critical control points (CCPs), and the limits for each CCP; as well as introduced CCP monitoring processes, procedures and corrective actions, ensuring your HACCP system functions as intended. 

Of these, FDA warning letters have tended to most often focus on corrective actions. The final rule requires a plant‘s HACCP plan to identify the corrective actions to be taken if a critical limit is not met. Corrective actions are intended to ensure that no product leaves the facility that has been adulterated or is dangerous to human health. 

Sesotec’s solution is HACCP, BRC, and IFS compliant.


THE GOAL

“We needed to provide our customers with the absolute security that the products we make for them are safe with no foreign contaminants“ says Nutradried Creations Plant Manager Phil Fraley. That‘s especially important for a company with a higher calling to help the economically disadvantaged. 

Working with Sesotec also gives Nutradried Creations more confidence when preparing for a customer audit. “We want to be ready,“ Phil said. “We want our customers to have confidence in doing business with us.“

THE SEARCH

Phil‘s team evaluated nine different X-ray suppliers. “We spent about twelve hours going through the capabilities for each,“ he adds. Ultimately, many things set Sesotec apart from the pack, but Phil cites one example: A commitment to quality training. 

“Sesotec included quality training in their fees and provided us with a great machine,“ Phil said. Competitors wanted to charge up to $5,000 to provide training, he added. He spent about four hours putting together spreadsheets and presented the Nutradried Creations‘ owners with the recommendation to go with Sesotec RAYCON Technology.


X-RAY INSPECTION SYSTEM RAYCON

In addition to metal, RAYCON product inspection systems can complete more advanced product analysis to detect contaminants, other systems might miss. Glass, ceramic, stone and bone in food can be problematic for an inadequate system. The RAYCON will detect high density plastics such as PVC and natural rubber, as well as identify other product defects including cracks, missing components and underweight products.

In addition, packaging components such as aluminum clips on sausage chubs or aluminum pie plates can be masked out as needed. RAYCON’s unique edge filter technology will analyze dense packaging edges in metal cans or carton walls, compensate for them; but still find foreign material at these edges. So 100% package inspection is always taking place with the RAYCON. Users like Nutradried Creations can operate with confidence with this kind of support.

RAYCON‘s innovative software also delivers a number of advantages. The use of real-time, solid-state flash memory, means no longer having to account for error-prone spinning hard drives. A Linux operating system - known the world over as a very robust industrial platform - allows for the full processing horsepower of a dedicated image analysis computer to find the smallest foreign material in food products. Finally, the electronic design is modular and rugged; no UPS is required for system protection, and access is easy, for lower cost of ownership.


THE FUTURE

Because of its partnership with Sesotec, Phil says the company will now be able to pursue larger partners, including private labels. “This represents a potentially big growth opportunity for Nutradried Creations,“ Phil stressed. “We benefit from working with partners who share our commitment to doing things well and doing them right.“ 

Phil and the team at Nutradried Creations remain committed to providing high-quality products that benefit people all over the globe. Working with a partner like Sesotec, they are confident they‘ll achieve their worthy goals. 

Nutradried Creations is a company full of dedicated, visionary professionals who firmly believe that getting also means giving. It‘s understandably proud of all that it has achieved by providing quality food inextricably linked with fair treatment of farmers and others in the production and delivery chain, but now it‘s hungry for more. At Nutradried Creations, the future is now.

BTB PET-Recycling GmbH & Co. KG, established in the year 2006, and headquartered in Bad Salzuflen (Germany) processes approx. 20,000 tons of PET bottles per year. The owner-managed company with about 30 employees primarily produces PET granulate both for bottle-to-bottle and for foil manufacturers. 

The PET bottles to be processed undergo a preparation process of several steps before they as PET flakes pass through the newly installed Sesotec flake sorting system. This system comprises a new chute machine of type FLAKE PURIFIER CM 1536 and an already existing belt machine from the year 2011,  which after modification could be integrated in the new installation. 

In accordance with the idea of BTB PET-Recycling GmbH & Co. KG, Sesotec in addition to the optical sorters also supplied the steel construction, the pneumatic conveying technology, and the control technology. The objective of this was to better coordinate the work that had to be performed, and to shorten the down-time of the complete plant in the construction phase. 

"Because of continuously falling prices for low-grade PET material on the Asian market we had to develop new economic solutions for PET waste, and our strategy was to reduce the waste volume", says plant manager Mr. Zajontz. "With the new installation of the Sesotec sorting system we have reached this objective. There is no question regarding the profitability of the system." He furthermore adds: "The integration of remote access makes it possible to monitor the sorting system through the network. Sesotec service engineers also can use remote diagnostics for short-term error remedying or for software updates, which makes processes in everyday operations much easier. Cooperation with Sesotec was smooth right from the start."

<![CDATA[USA and the Food Safety Modernization Act]]> 2018-04-02 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/usa-and-the-food-safety-modernization-act https://www.sesotec.com/emea/en/resources/blog/usa-and-the-food-safety-modernization-act Food

In an article from the year 2013 the Food Sentry company that watches the origin of food on a global level writes that this standard is violated especially in India and China. The ASEAN region in Southeast Asia, on the other hand, with respect to safety regulations clearly stands out from these two countries and is also considered a true power producer of food – with an export total of approximately US dollar 53 billion in 2011 in the agricultural sector.

The unlimited flow of food within this market is hindered by several safety regulations: Before food in the ASEAN region can be marketed in Southeast Asia, it is checked for certified production and in some countries first registered in order to guard against and counteract possible risks. Anyone who cannot prove certified production of his product will not be allowed to import or export in these nations.

In the United States there are clearly defined regulations for the observance of food safety standards for a long time. Currently the Foreign Supplier Verification Program (FSVP), which entered into force on 30 May 2017 within the scope of the Food Safety Modernization Act (FSMA), should ensure that the safety and quality of all the food imported into the United States are guaranteed helping to protect the consumer. Originating from the U.S. Food & Drug Administration (FDA) the FSMA was signed already in the year 2011, but it only took effect in September 2016. Food producers who export into the United States therefore must be aware now that food purity and quality should no longer only be seen as competitive advantages, but rather as an obligation and an established standard.  

 

What is the FSMA?

The Food Safety Modernization Act is a resolution originating from the FDA (Food & Drug Administration) that aims to ensure the fulfilling of safety and quality requirements in the US food industry. With the now effective FSMA the FDA now have a wider scope of action with respect to measurements and inspections at food producers in order to avoid possible risks for consumers, which for example may result from contaminations.


What does the resolution mean for trade?

Food producers who export to the USA must ensure that their products comply with FSMA regulations. This means that food should be produced in certified production processes – which for example includes the fulfilling of necessary hygiene requirements, the inspection of products with inspection systems, and the documentation of potential risks.


In detail

  • ƒCompanies that import into the USA according to the FSMA must demand from their sub-suppliers that they perform these inspection measures with their products.
  • ƒThe FSMA authorises the FDA to refuse the acceptance of imported food if the foreign-country establishment refuses to be inspected by the FDA.
  • ƒThe resolution furthermore allows the FDA to request a compliant certificate from food producers that ensures that imported food complies with the US food regulations.


When does the FSMA take effect?

According to the FDA, the obligations to comply with FSMA regulations have been in force since March 2018.


Contaminant inspection systems are important components for FSMA compliance

The objective of the FSMA is to guarantee food safety. A first important step for proper preparation is the so-called Hazard Analysis and Critical Control Points concept (HACCP): The identification of critical control points. Critical control points are those stages in the production process that allow inspections which lead to a reduction of hazards for food purity. It may be decisive here, for example, whether the product should be inspected in packed or unpacked condition, when goods are received or at the end-of-line. Another decisive factor is the type of inspection. Here the type of contaminant must be determined, or whether product-related quality differences should be detected. The FSMA also includes the so-called HARPC concept (Hazard Analysis and Risk-Based Preventive Controls) which specifies preventive measures against possible risks with the aim of implementing inspections and verifying the success of such inspections. A good inspection system features sophisticated and reliable technology, high-quality workmanship, and user-friendly innovative operation. Users who choose magnet systems, detection systems, X-ray systems, and optical sorting systems made by Sesotec can be sure that all the above-mentioned criteria are fulfilled.

Sesotec offers a wide product portfolio that covers almost all applications. Customers from all over the world can be supplied with systems for all process stages, products, and conveying types. Sesotec systems are produced at the main factory in Germany and comply with highest safety requirements and with hygienic design that is required for the world market. Control unit and software design are developed to ensure that they comply with the requirements of HACCP and all the current food standards.


Result: The benefit of FSMA is higher than the efforts

Apart from the expenditure in money and time due to the installation of inspection systems, the Food Safety Modernization Act also offers many benefits. The resolution not only can be seen as a chance to guarantee food safety, but also as a safeguard against damage to a company‘s brand image that may result from recall campaigns.

Innovative Plastics is employing over 9,000 people worldwide, manufacturing high-end thermoplastic materials in more than 35 countries. SABIC is working on the principles of Six Sigma. The highly disciplined Six Sigma process helps them to focus on developing and delivering near-perfect products and services. It encompasses design, production, and distribution. The product quality improvements behind SABIC Innovative Plastics‘ materials can help enhance the quality and marketability of customers‘ end products.

Task

In Bergen op Zoom SABIC is producing plastics compounds PC, PC blends and Noryl. Quality and Product Purity is extremely important for SABIC. So they were looking for a machine for their outgoing quality control. Highest scanning sensitivity for ferrous metals, but also stainless steel and other non-ferrous metals was required. They requested for the best sensitivity in combination with reliability, aftersales and a supplier who has experience in plastics.

Solution

PME is one of the leading suppliers of peripheral equipment for the plastic processing industry in the Netherlands. They not only represent foreign and domestic producers but also provide service, maintenance, engineering and project management for all the peripherals for injection moulding machines, extruders, blow moulding machines and other machines producing plastics, plastic semi-manufactured products, and final products.

As a long term partner of Sesotec in the Netherlands PME offered RAPID PRO-SENSE metal separators to SABIC. Using innovative HRF technology (High Resolution Frequency), RAPID PRO-SENSE, a system for free-fall applications, features extremely high sensitivity to all metals. The metal separator is specifically designed to meet the requirements of plastics and compound producers and features a genuinely innovative modular design. The reject unit can be chosen to match the conveyed material or to meet specific customer needs. 

As SABIC’s material inspection of the end product happens before packaging with special requirement that the unit must be cleanable with water inside. So water tightness of equipment is necessary. In part, the material is also abrasive. Wear-down protection of equipment is an important point. Last but not least there is a need of customized fitting to local installation requirements with special flanges.

SABIC decided to use RAPID PRO-SENSE metal detectors of Sesotec because of its outstanding features especially regarding the scanning sensitivity which is on highest level compared to other existing metal detectors. Another convincing feature is the reject mechanism where material cannot deposit which is important in case of material changes. Also the self-cleaning feature of the reject mechanism of RAPID PRO-SENSE is unique. The surface of parts in contact with material has been specially treated so that it is more resistant against wear-down.

Result and customer statement

The long experience with plastics handling and the aftersales in the Netherlands by PME is one more reason why Sabic bought RAPID PRO-SENSE metal detectors. Ronald van der Wal and Rob Willems from Sabic confirm: “The first units of RAPID PRO-SENSE are running in production very well. We are very satisfied with the results.”

PT. Rejeki Adigraha is a well-known plastics recycling company in Indonesia primarily specialising in the recycling of PET and PVC materials. PT. Rejeki Adigraha is headquartered in Jababeka Industrial Area – the largest industrial area in Southeast Asia. With about 150 employees the company reaches a recycling capacity of approximately 1000 tons of PET and PVC per month. 

PT. Rejeki Adigraha already was established in the year 1986 under the name of UD Rejeki Adigraha. At the beginning of its corporate history the company operated as a small trading company for PVC pipeline component brands and later also established itself as a manufacturer of rigid PVC granulate especially for pipeline components. At that time PT. Rejeki Adigraha was the first company in Indonesia that produced recycled PVC granulate for the pipeline component market.  In addition to granulate the company also produces PET flakes that are used as starting material for the polyester industry. PET products at present mainly are exported to China. 

Sesotec Asia, one of Sesotec's eight subsidiaries, based in Singapore, established the contact with PT. Rejeki Adigraha. 

PT. Rejeki Adigraha has replaced the manual sorting of PET and PVC flakes with automated sorting technology of Sesotec. "With the  FLAKE PURIFIER multi-sorting-system we have achieved a clear increase in efficiency. The quality of recycled plastics is guaranteed at highest levels and without any quality fluctuations," confirms Mr. Dede Indrapurna of PT Rejeki Adigraha. 

The recycling process of the Indonesian company starts with plastic materials from residual waste and plastic flakes containing 70 percent PVC and 30 percent other plastics, mainly PET. The material first is shredded to obtain parts of approximately the same size, and then passes through washing and drying processes. In the next plastics processing step Sesotec's FLAKE PURIFIER multi-sorting-system is used for the separation of PVC. The FLAKE PURIFIER sorting system was specifically developed for applications in the plastics recycling industry. The especially adapted small conveyor ensures that the plastic flakes are optimally singularised. In addition to the sensors for metal and colour separation Sesotec also provides a high-performance module for the detection of contaminations, which also include different types of plastics. Depending on the application these sensors are used individually or in combination. 

PT Rejeki Adigraha today can look back on more than 20 years of experience in plastics recycling. By using state-of-the-art recycling technologies the company has expanded its PET flake and PVC granulate production and thus is able to provide its customers with materials of highest quality.

<![CDATA[Sesotec Plastics Sorting – Fast, Reliable, Pure]]> 2018-02-07 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/plastics-recycling-with-sesotec-sorting-systems https://www.sesotec.com/emea/en/resources/blog/plastics-recycling-with-sesotec-sorting-systems Case Studies

All over the world waste plastics are a highly complex recycling subject. Nowhere else is there such a large number of different materials that need to be sorted. The pure sorting of waste plastics and their returning into the raw material cycle is particularly relevant both from an ecological and economical point of view. The correct sorting technology is of outstanding importance here. 

In the sorting of plastic bottles into pure plastic fractions the Taiwanese recycling company Tong Yi is serviced by Sesotec Pte.Ltd., Singapore, together with the distribution partner Uniplast Corporation. Tong Yi automates plastic bottle sorting with the Sesotec VARISORT N recycling sorting system.

Tong Yi specified the sorting requirements that have to be met. Test material from Tong Yi was sorted in the technical laboratory at the Sesotec headquarters in Germany. The customer thus had the opportunity to convince himself of the results and capabilities of the recycling sorting systems.

Optimal sorting solution for individual recycling requirements

Tong Yi uses the VARISORT N recycling sorting system – based on multispectral analysis – for the reliable sorting of plastic bottles, and thus gets two high-quality plastic fractions, PE and PET. 

A special challenge at Tong Yi is that the bottles to be sorted are transported on the conveyor belt in unpressed form. This leads to additional rotation of the bottles, which is countered by a special belt design. The conveyor belt with a length of five metres furthermore is used to singularize the whole bottles that should be sorted, which further increases the reject accuracy in the separation process.

The VARISORT version that is installed at Tong Yi features a three-shaft design, which means that three fractions can be separated in one sorting process. Fraction 1 contains PE, fraction 2 PET, and fraction 3 the other plastics and materials.

Depending on future sorting requirements and materials the customer can retrofit his existing system with additional sensors. This combination of different sensor types apart from plastics separation also allows applications in the fields of colour sorting and metal separation.

<![CDATA[MB-Sort – Recycling of Metal Waste and Plastics with VARISORT COMPACT]]> 2018-02-06 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/mb-sort-recycling-of-metal-waste-and-plastics-with-varisort-compact https://www.sesotec.com/emea/en/resources/blog/mb-sort-recycling-of-metal-waste-and-plastics-with-varisort-compact Case Studies


MB-Sort is headquartered in Schönberg in the heart of the Bavarian Forest. Established in August 2016 the company presents itself as a specialist for material recycling on a market with great potential and offers professional contract sorting of all kinds of complex and technically problematic materials. The objective is to recover secondary raw materials from different kinds of mixed fractions, for example from electric and electronic waste, metal waste, and plastics.

Task

Every month MB-Sort recycles up to 200 tons of various mixed fractions. Its customers include recycling companies and companies from the manufacturing industry. "In our own sorting line the material must be sorted into different material groups or cleaned. Sesotec's VARISORT COMPACT system is optimally suited for this task", says Markus Burghart.

Solution: VARISORT COMPACT

The material to be inspected is fed into the VARISORT COMPACT system by means of specifically adapted vibration feeders that ensure a homogeneous material transfer onto the full width of the high-speed belt conveyor. The combination of infeed slide and belt conveyor eliminates form, weight, and friction influences of the material that is fed in. At the end of the belt conveyor the material is classified by means of corresponding sensors. After evaluation of the relevant information, highspeed valves are activated with a corresponding delay time for material discharge. Particles that must be separated are deflected from their original trajectory by exactly targeted compressed-air blasts and thus fall into a separate shaft.

Fields of application

The VARISORT COMPACT CM+ recycling sorting system among others is used for the sorting of shredded small electric/electronic devices. The purpose of sorting here is to separate printed circuit boards, copper, aluminium, stainless steel, and to generally remove metals from electronic waste plastics.

In multi-sensor operation the C and M+ sensors are combined. The C sensor unit provides information about form and colour, and the M+ sensor is responsible for metal detection. With this combination a high metal purity can be achieved and a usable plastic fraction can be obtained as a result.

In metal recycling the objective is to achieve correct sorting of the metal mixture consisting of aluminium, zinc, copper, brass, and stainless steel. Sesotec's VARISORT COMPACT CM+ system ensures reliable recycling with purities of more than 98%.

For plastics-processing companies different production waste or regrind materials must be separated by colour. Once recycled, these materials can be fed back into the production cycle again. With the C colour detection sensor the VARISORT COMPACT system is optimally suited for this task.

Result

At MB-Sort the VARISORT COMPACT system made by Sesotec allows high-precision sorting of different material mixtures with high throughput rates.

Conclusion: VARISORT COMPACT is a flexible sorting system

With the VARISORT CM+ recycling sorting system MB-Sort is able to perform many tasks of its customers with highest flexibility.

The company continues to expand both home and abroad and in 2006 built a completely new production facility. This advanced factory extends over 18,000 square metres and incorporates all the latest equipment to enhance product quality and increase customer satisfaction. The company meets  all IFS, ISO 9001 and HACCP standards and holds many certificates and awards for consistently high product quality.

The new plant utilizes the latest in bulk material handling technology designed, supplied and installed by engineering company Johann Daxner GmbH who specializes in providing integrated plant and machinery projects particularly for bulk material processes.

Sesotec, in partnership with Daxner, supplied IFS and HACCP compliant food metal detectors for product inspection on milling, mixing, filling, bagging and small component lines. Food metal detectors from the Sesotec RAPID 5000 range were installed at the large bag filling station.




IFS Conformity

For Almi it was particularly important to choose metal detection systems that fulfilled all the requirements of HACCP and IFS in the food industry. RAPID 5000 metal detectors detect and remove magnetic and non-magnetic metal contaminants from free-falling bulk materials.

The contaminants are removed by means of a fast-reacting reject flap (“Quick Flap System”) with minimal loss of good material. The modular design concept means that the machines can be easily adapted for different drop heights by removing or adding intermediary pieces.

One of the main reasons for installing Sesotec machines was their “Hygienic Design”; specifically designed and constructed to meet the exacting hygiene standards of the food industry. The circular design of the reject mechanism eliminates sharp edges and crevices, preventing product build-up and blockages, even with non free-flowing flavourings, avoiding product build up over time and the resulting mould formation.

The „Easy Clean“ construction of the reject device means it is straightforward to access for cleaning and maintenance. The RAPID 5000 metal detection systems are also certified for ATEX Zone 20 because flammable dust is created during the filling/bagging process.


E R P and Metal Detection at Almi

A particular challenge of this application was varying product effect of individual flavouring product which can cause false triggering and material loss. To obtain optimum performance machine parameters for each product must be easily set up for each of the different product mixes.. Through the integral Ethernet interface attached to each metal detector the higher-level ESAweight production control system uploads  system parameters for each product batch.

Another feature that distinguishes the Sesotec machines is their high level of detection accuracy. The GENIUS controller and operating unit utilizes digital signal processing technology and ensures that the detector head is finely tuned to operate at optimum efficiency. Even particularly difficult, highly conductive spices and flavourings can be tuned out and optimum scanning sensitivities achieved.

The time and data of every event is recorded via the integrated logbook function. The GENIUS controller communicates all  relevant data for recording and traceability to the ESAweight control system, for subsequent processing batch by batch in the  central database. Analysis of the rejected material provides important information on the source of contamination and Almi have set up an additional station specifically to examine rejected material.


Result

Robert Leeb, Production Manager at Almi is delighted with the results, “Sesotec RAPID 5000 metal detectors meet all our exacting standards and play a vital part in our complex quality management system.”

<![CDATA[Metaldetector allows economic processing of regenerated material]]> 2018-02-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/metal-detectors-allow-economic-processing-of-regenerated-plastics https://www.sesotec.com/emea/en/resources/blog/metal-detectors-allow-economic-processing-of-regenerated-plastics Case Studies

In the production of plastic parts for industrial electronics and automotive components, whether in small series with less than 500 parts per year or with annual production volumes of several million parts, the requirement for maximum process reliability has top priority. Environmental as well as economic considerations result in the use of industry-grade granulate (regenerated material, regrind) for plastic parts that in the end often are not visible, because a slight loss of optical properties is not important here.

The processing of regenerated material and regrind, however, is complicated by possible contaminations with foreign substances such as metal particles. Depending on the production system this may cause unwanted machine downtimes due to damage or clogging. The apparent economic advantage thus is quickly lost if downtimes caused by contaminations cannot be avoided. Using metal separators is the most reliable method for removing metal particles.

Sesotec provides metals separators for the inspection and purification of plastic granulate (new material and industry-grade material). The metal separator of type GF, for example, is especially suited for installation in vacuum and pressure conveyor pipes. Once installed it ensures undisturbed production. Only the use of metal separators allows an economic processing of granulate mixed with regenerated material or regrind.



The GF metal separator removes metallic contaminations (steel, stainless steel, aluminium, etc.) from the pneumatically conveyed regenerated material. Installed directly in the vacuum conveying pipe of the material conveyor for the injection moulding machine, it reliably separates metallic contaminations, even such contaminations that are embedded in a granulate grain. With the "Easy Mount System" the metal separator can be installed in already existing vacuum conveying pipes without any problems. Parts in contact with the product are made of stainless steel (1.4301). The outwardly sealed reject unit prevents any impairment of the function of the material conveyors due to outside air.

Product effects of the bulk material that are caused by moisture, colour pigments, or carbons, are automatically compensated, which guarantees a constant scanning sensitivity. With default settings the systems provide outstanding ease of operation. One advantage of the fast-acting "Quick-Flap-System" is the minimum loss of good material. Contaminated material is collected in a collection container and is thus available for detailed analyses.

Says Gerhard Kerschhackl, area sales manager of Sesotec Business Unit Plastics: "Sesotec metal separators are absolutely state-of-the-art, of outstanding quality, and they operate with highest reliability. Sesotec systems provide a rapid return on investment because they prevent the causes of downtimes and expensive repair work and guarantee optimal machine running times and product quality. Customers from the plastics-processing industry who have once acquired a metal separator to protect their machines later in most cases also purchase additional systems."

Thermoplastkreislauf GmbH is headquartered in the Lower Austrian town of  Traiskirchen near Vienna. As a specialist in the field of thermoplast refining the company in its "Production" business unit produces individual plastic granulates by means of sophisticated compounding processes. The recycling of high-quality thermoplasts is the company's second business unit. The objective of this business unit is to process production waste into high-quality regrinds or regranulates.

All the products – new material, regrind, regranulate, and recyclate – undergo stringent quality inspection, and it is also of great importance here that products are of pure colour and correct form, and metal-free.


Sesotec sorting station with integrated multi-sensor sorting system

In its recycling business unit Thermoplastkreislauf GmbH installed a sorting station designed by Sesotec. Sesotec supplied a customised station with suitable steel construction, conveyor technology, and multi-sensor sorting system. The scope of delivery also included feeding hoppers, conveyor belts, steel construction for screens and working platform, and a suitable  SIEMENS control unit. For easy cleaning of the conveyor belts in case of material changes, mobile folding conveyors were integrated in the sorting station.

The core component of the sorting station is the VARISORT COMPACT multi-sensor sorting system that is equipped with sensors for colour and shape detection and with an all-metal sensor. The sorting station furthermore includes various screens that remove oversized and undersized particles before the material is transferred into the sorting system. The VARISORT COMPACT multi-sensor sorting system separates unwanted colours, shapes, and metals from the plastic flow and thus guarantees a constant high quality of the plastic recyclate. The unmixed products in additional steps are processed into granulate or are returned to the customer for further processing.

Says Christian Wind, managing director of Thermoplastkreislauf GmbH: "The project was perfectly planned and smoothly executed by Sesotec. We greatly benefit from the experience and flexibility of Sesotec in the field of sorting technology, because we can now guarantee that our products meet highest quality demands."

The AptarGroup is a global market leader for dosing systems with more than 50 years of experience in a constantly changing world of packaging.  The most important corporate objective of the AptarGroup is to provide safe products for the business segments beauty+home and pharma. This objective is reached by using state-of-the-art technology. For the complete development, procurement and production processes the AptarGroup has set highest standards for itself.

In the business unit for fragrances, skin care, and cosmetics Aptar provides innovative, reliable, and flexible solutions. Packaging systems for beauty products must combine perfect function with attractive aesthetics. For demanding customers from the cosmetics industry Aptar is a partner for the providing of ideal beauty product packings. The product portfolio includes pump dispensers, caps and valves for skin care products, as well as spray pumps. Aptar also develops and produces complete packings and customer-specific solutions. At the Neubourg production plant in France Aptar Beauty+Home among others is certified acc. to ISO 14001:2004 for the development and production of spray and dosing systems as well as small packings.


Soufflet provides a test system

At Aptar in Neubourg the components for perfume sprayers are produced with injection-moulding machines. For the observance of quality standards the use of Sesotec metal separators is of decisive importance there. To convince Aptar of the high performance of such machines, the French Soufflet company provided a PROTECTOR system for testing for a period of six months. The advantages and improvements that this PROTECTOR system provided were quite obvious: A higher output of products of perfect quality, and reduced down-times of injection-moulding machines. The resulting rapid return on investment and the excellent cost/performance ratio in the end were the decisive purchasing arguments for Aptar.


Metals in plastic granulate may clog hot runner nozzles

Long before the use of metal separators, magnet grids were inserted in the material feeders of Aptar production lines that predominantly comprise injection-moulding machines. These magnet grids, however, were not efficient enough to remove all metal particles from the hot plastic material. Furthermore, magnets only attract ferrous metals.


Metal separators as the perfect solution for Aptar

For more than five years Aptar therefore has been using Sesotec metal separators of the PROTECTOR type for the protection of its processing machines. These metal separators are installed directly above the material inlet of injection-moulding machines. They detect all magnetic and non-magnetic metal contaminants (steel, stainless steel, aluminium, …) even if such contaminants are enclosed in the product. Metal particles are removed by means of a "Quick Valve" reject unit. The PROTECTOR metal separators are perfectly adapted to Aptar's requirements.  


Detection accuracy convincing for Aptar

Both Aptar's plant maintenance engineer and production manager consider  Sesotec metal separators as an important component in quality assurance: "We are particularly convinced by the detection accuracy of these systems. The daily performance tests demonstrate that the systems operate reliably, that fewer metal particles reach the injection-moulding machines, and that these machines therefore are reliably protected against functional disturbances. To this day we have installed more than 20 PROTECTOR in our production lines."


PROTECTOR protects in many applications

In its application possibilities the PROTECTOR offers highest flexibility. For example the metal separator is ideally suited for application in the packing industry in the production of caps for beverages and other liquids, or in the production of plastic articles for medical technology. Metal separators prevent malfunctions and thus increase the productivity of plastics processing machines.

About SUZUKI MOTORCYCLES  

SUZUKI MOTORCYCLES INDIA PVT. LTD. is a subsidiary of Suzuki Motor Corporation, Japan, and in the Indian town of Gurgaon (Haryana) operates a plant with 1.700 employees and an annual capacity of 750.000 motorcycles and scooters. 

The core of Suzuki's philosophy always has been to provide bikes that are optimal in form and function. Their products are based on the effort to implement customer wishes and demands in development. 

Quality inspection is of outstanding importance for SUZUKI All the components of a bike undergo thorough inspection and quality testing. To ensure that material and aesthetic demands of the product are met, individual parts undergo performance testing before they are released for assembly. For efficient testing SUZUKI. has installed state-of-the-art inspection and testing machinery, which includes metal separators of the Protector range of Sesotec.

Task

Plastic parts for motorcycles are produced in injection-moulding machines and are then painted. For the production of plastic parts for these 1.500 vehicles per day, SUZUKI. uses both new granulate and recycled material. The processing of recycled material and regrind, however, is complicated by contamination with  metal particles. This may cause unwanted downtime of the expensive injection-moulding machines and Hot Runner Systems of the mould due to damage or clogging.

Solution  

Using metal separators to remove metal particles is the most reliable method to prevent machine downtime and quality defects. The Protector metal separator is installed directly above the material inlet of an injection-moulding machine, extruder, or blow-moulding machine. It detects all magnetic and non-magnetic metal contamination (steel, stainless steel, aluminium, ...) even if they are embedded in the product. Metal contamination is removed by the reject unit ("Quick-Valve").

At SUZUKI. a height of only 350 millimetres was available for installing the metal separators on the injection-moulding machines. With its slim and sturdy design the Protector is a perfect fit. The high-temperature version the Protector ensures perfect processing of the 90°C to 110°C hot granulate. External interference is compensated by the  Auto-learn function. Preset operating parameters ensure outstanding ease of operation.

Customer statement

Vipul Vikas, Project Manager at SUZUKI., is highly satisfied with the Sesotec Protector metal separators: "We were actively searching for a solution to solve the problem of metal contamination, and we found Sesotec through the manufacturer of our injection-moulding machines. Our Sesotec metal separators operate successfully, productivity has increased by five percent."

About Brückner Maschinenbau

Founded in 1960, Brückner Maschinenbau GmbH & Co. KG, Siegsdorf, today is the globally leading supplier of production lines for the manufacture of high-quality mono- and biaxially stretched film as well as extruded and smoothed flat film. Brückner Maschinenbau also provides complete turnkey plants as well as laboratory and pilot plants.

Brückner Maschinenbau is world market leader in the field of film stretching technology. Brückner's lines guarantee film manufacturers an efficient, flexible and reliable production of a wide range of film types that are used as high-quality packaging materials and in technical applications (e.g. capacitor film and high-tech screen film).

Today, approximately 600 Brückner film production lines are in operation all over the world. The customer list includes all the large and renowned international film producers. For many years Sesotec, Schönberg, has maintained a customer and supplier relationship with Brückner. For decades Brückner has acquired metal separators from Sesotec for the inspection and purification of film raw materials (film shreds, ground material, and new material).


Task

In the production of films the edges, which due to the production method are somewhat thicker, are cut off, creating long strips that are recycled in the company. For this purpose the film strips are ground in a mill, and the ground material is added to the starting material again.

To guarantee the reliable removal of possibly included metal particles which, for example, might get into the material during the grinding process, the film flakes pass through metal separators before they are processed. Film stretching machines and extruders thus are reliably protected against damage caused by metal particles.


Solution

Brückner uses Sesotec metal separators of type RAPID DUAL at central positions. This separator type is excellently suited for the inspection of non-free-flowing bulk materials such as film shreds and of high-volume material flows in free-fall conveyor pipes. The separator detects all magnetic and non-magnetic metal contaminations (steel, stainless steel, aluminium, ...), even if such contaminations are embedded in the product.

Metal contaminations are ejected by a double flap ("Quick Flap System"). This eject system keeps the loss of good material at an absolute minimum. Using Jacob standard pipe connections the metal separator can be easily installed in existing pipes with minimum effort and in no time at all. Product-contacting components are made of stainless steel.


Benefit

  • Detects and separates magnetic and non-magnetic metal contamination, even when enclosed in product
  • Reduces expensive machinery failure and minimises production downtime
  • Ensures product quality
  • Prevents customer complaints
  • Break even within a very short period of time


Result

"In matters of metal separation, Brückner and Sesotec have been cooperating on partnership basis for decades. Brückner is satisfied with Sesotec because our metal separators are state-of-the-art in their technology and are of highest quality in their construction. Our systems operate reliably, reproducibly, and they amortise in a very short time because they prevent the causes of downtimes and expensive repair work and thus guarantee optimal machine operating times and product quality", says Erwin Reitberger, Sesotec Branch Manager - Plastics Industry.

<![CDATA[Andritz: High-quality plastics from waste electrical equipment]]> 2018-01-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/andritz-high-quality-plastics-from-waste-electrical-equipment https://www.sesotec.com/emea/en/resources/blog/andritz-high-quality-plastics-from-waste-electrical-equipment Case Studies

Throughout Europe, electrical and electronic scrap is the highest growing waste stream and  since electronic equipment contains a wide variety of materials, the recycling of such waste makes significant demands on any separation and sorting processes. The German plant builder, ANDRITZ MeWa, has built and commissioned a state of the art WEEE plant in the UK for a major waste management company incorporating a number of Sesotec sorters.  Designed to process recycled refrigerators, computers, hifi systems and other types of electronic and electrical waste the plant operates with two separate lines.

Sesotec has supplied through ANDRITZ MeWa three WEEE-SORT N near infra-red sorting systems for the identification and recovery of  high-quality plastics such as ABS , polycarbonate and the recycling of printed circuit boards. "The decision to use Sesotec systems was based on the high output quality of  WEEE-SORT systems. Only the most pure fractions can be sold at the best price ", explains Michael Perl, business manager - sorting at Sesotec.




Innovative technology for outstanding value creation

WEEE-SORT N polymer sorters are based on near-infrared technology. At the ANDRITZ MeWa facility these systems operating fully automatically separate different types of plastic pre-crushed electrical waste. The material stream to be inspected reaches the infra-red detector spread across a  fast-running conveyor belt and at this point the position and type of plastic is identified. Then depending on which types of plastic have been selected for separation but the user unwanted types are accurately and precisely removed by a precision air blast ejection system mounted at the end of the conveyor belt.

One of the three WEEE-SORT systems has a colour sensor combined the infra-red unit which provides a combined sorting process based on both colour and polymer type.

Recycling materials is  cost effective and environmentally friendly

Sesotec WEEE-SORT N polymer separators operate with high throughput  capacities and the sorting belt runs at up to  3m/sec. Air-blast valves,  specifically developed for this application, keep the loss of good material to an absolute minimum. For WEEE  recycling WEEE-SORT systems are a cost effective solution for the reclaiming of high-quality plastic and pcb fractions. The resulting pure plastics can be profitably returned to the production cycle , and valuable  metals can subsequently be reclaimed from the separated printed circuit boards.

Flexible and future-proof solutions provided by Sesotec

Says Michael Perl, business manager - sorting technology at Sesotec: "Recycling companies that produce clean, economically-priced material have a tremendous competitive advantage. The outstanding flexibility of WEEE-SORT systems makes them ideal for the sorting of electrical waste.

The markets for recycled materials are rapidly changing especially in the field of electrical waste, and since quality requirements for recycled materials are high, and recycled material has to compete with the price of new materials, the WEEE-SORT sorting system with its flexibility is a future-proof investment: the technologies employed and the techniques used are highly sophisticated and  provide high-purity material fractions."

<![CDATA[Food Metal Detectors for Kalustyan]]> 2018-01-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/food-metal-detectors-ensure-quality-at-kalustyan https://www.sesotec.com/emea/en/resources/blog/food-metal-detectors-ensure-quality-at-kalustyan Case Studies Customers and federal regulators expect more and more from suppliers in today’s increasingly competitive and federally-monitored marketplace. New tools and technologies offer effective ways to meet those needs with easy implementation, reasonable costs, and immediate benefits. 

In this case study, sweets and spices purveyor Kalustyan, a long-time customer, reports on its experience with Sesotec, including how Sesotec’s array of product solutions is fueling growth.

For Kalustyan, a spice and herbs processing company located in New Jersey, the new and revised federal regulations posed significant new compliance challenges. In addition, its largest customers were demanding assurance that Kalustyan’s products were up to the mark. “Our quality system is based on Global Food Safety Initiatives (GFSI) and is the backbone of our organization,” said Abdul Basit Gaba, director, quality/food safety.

“We have a systematic assessment of each step of our production processes through our HACCP plan and a proactive and preventative control of all raw materials, processing activities, and our processing environment.” To meet its customers’ growing needs, Kalustyan knew it needed to find new solutions.

“Our customers appreciated the fact that we were tackling the new regulatory requirements head on,” said Fernando Porras, Kalustyan’s VP of operations. But Kalustyan also knew it needed more than a technically superior solution. It had to demand a solution that was easy to understand and operate, known for reliability, and offered at a reasonable price. “We believe that our success depends on the supply of safe quality products that meet or exceed our customers’ expectations,” said CEO Errol Karakash.




A CLOSER LOOK: KALUSTYAN

Kalustyan has been in the business of sourcing spices and herbs globally since its founding in 1977. It has a long history of sourcing from places including Armenia, Australia, Bangladesh, Belgium, Bulgaria, China, Egypt, England, France, Germany, Greece, Guatemala, Holland, Indonesia, Iran, Israel, Italy, Japan, Jordan, Lebanon, Malaysia, Morocco, Pakistan, Philippines, Romania, Spain, South Africa, South America, Saudi Arabia, Sri Lanka, Syria, Thailand, Tunisia, Turkey, Vietnam, West Indies, Yugoslavia and many others. The products are characteristically more challenging when it comes to procuring and producing adulteration-free products while also meeting Good Manufacturing Processes (GMP).

Achieving a BRC rating of “A” for the last three years, along with Customs Trade Partnership Against Terrorism (CTPAT) certification, Kalustyan has also deployed a long-standing, positive control-based, quality assurance approach to prevent adulteration and provide safe product to many of the leading manufacturers in the world. “Over time, we have refined our programs to further guarantee the quality and safety of our products,” Abdul added. Kalustyan has manufacturing operations in three countries so far, and the company takes its commitments to quality work in each location very seriously, Abdul stressed.


THE SEARCH FOR A SOLUTION

For Kalustyan, the search was relatively easy. After trying out a number of competing solutions, it made a lot of sense to stick with Sesotec. “From a cost perspective, they were about in the middle of the pack, but from a dependability and performance perspective, Sesotec was at the head of the class,” Abdul reported. “Sesotec delivered the most effective and effi cient method to assure the absence of economic adulterants and contaminants in the product.”

Another critical factor: Kalustyan is already operating more than a dozen Sesotec metal detectors and x-ray products. “Because some of our products are packaged in foil, we need more than a basic metal detector. We require the extra comfort of x-ray inspection,” Abdul added. “Sesotec meets or exceeds our requirements every day.”




A CLOSER LOOK: THE SESOTEC SOLUTION

Kalustyan leverages three Sesotec solutions: RAYCON X-ray Inspection System, and two designs of gravity free-fall metal detectors, the RAPID 4000 and the RAPID 5000.

The RAYCON X-ray Inspection System is very easy to operate and is notable for several unique performance capabilities. These include a full product inspection window without blind corners that assures 100 percent product inspection regardless of product height or placement on the belt, precision-matched x-ray source/detector, combined with Sesotec’s unique methodologies for x-ray analysis to provide the highest level of detection of dense foreign materials such as metal, stones, bone, HD plastics and glass. A real-time operating system performs at up to 600ppm with simultaneous inspection of up to four lanes running in different products in parallel.

The RAPID 4000 is used for the inspection of spice and grain materials to detect and reject magnetic and nonmagnetic metal contamination, even when enclosed in the product. It also ensures product quality, prevents customer complaints, and provides a quick return on investment when used to protect against expensive processing machinery failures thus maximizing production uptime efficiency.




The RAPID 5000 operates as an effective metal detector for the inspection of powdery and fine-grained bulk materials. It detects and rejects magnetic and nonmagnetic metal contaminants, with a unique elliptical stainless steel reject flap diverter. The leading hygienic design does not have any corners or niches that can be harborage areas for pathogen growth, making it suitable in applications where high sanitary standards are required.

Finally, all Sesotec solutions are BRC, IFS and HACCP compliant.


EASY IMPLEMENTATION

Implementation of the system upgrade began in June 2014. It was a smooth process, eased by Sesotec’s simple operation and easy to understand communications. “We knew it would work,” Abdul said. “Our track record with Sesotec made us confi dent of that.” Kalustyan had already installed a new Sesotec X-ray detection device in 2013 and Abdul reported “we are very happy with it and look forward to growing the relationship.”


NEW BEGINNINGS

Working with Sesotec, the NJ-based operation continues to import and manufacture products from all corners of the globe in order to meet the specifi cations of its customers. “It feels good to work with a vendor partner who understands our mission and is helping us to achieve it,” Abdul adds. Kalustyan has plans to purchase more equipment from Sesotec. “It’s been nothing but a positive experience for us, and we’d like to build on that success,” Abdul says. For a spice maker with a historic legacy, the future looks nothing but bright — with a touch of distinctive flavor.

About Starlinger & Co. Gesellschaft m. b H.

Austrian company Starlinger GmbH is a  global market leaders in the field of machinery and process technology for woven plastic sacks.

Since 1987 the company has manufactured and supplied recycling lines for plastics, and in 2002 established the  "recycling technology" division. This division includes innovative machine solutions for the efficient recycling of a wide range of plastics including PE, PP, PA, PS, PET, and others.

Starlinger employs new recycling technologies and a well proven and established machinery concept and since the beginning this concept has included metal detectors from Sesotec.




Task

Plastic shredding is the first step in the recycling process and at this stage since metal contamination can cause damage to  downstream modules reliable metal detection is therefore indispensable. Consistent metal separation prior to shredding reduces malfunctions and increases the profitability of the recycling lines and for this purpose Sesotec C-SCAN DLS type detectors are used and are mounted over the conveyor system prior to the shredder.

Solution

C-SCAN DLS detectors will detect magnetic and non-magnetic contaminants even if they are embedded in the product and by removing contamination prior to the process reduce costs due to machine damage and production downtime, guarantee product quality, and protect against customer complaints. C-SCAN DLS metal detectors can offer a rapid return on investment.

Customer Benefit

C-SCAN DLS metal detectors offer many advantages: They prevent metals from reaching cutting machines and thus avoid wear and broken cutting tools. They reduce downtimes and maintenance costs, they improve the quality and value of the cut material, they reduce malfunctions and off-times in downstream processing machines, and they minimise quality defects and reject rates in recycled plastic materials.

Result

Andreas Pechhacker, technical manager of Starlinger "recycling technology" is very satisfied with the result: "Starlinger has used Sesotec metal detectors for several years. The systems are highly robust, offer flexible installation capability, and operate with outstanding reliability. Return on investment is ensured in a very short time because the blades of the agglomerator or single shaft cutter and downstream extruder screws are protected. Expensive repairs are a thing of the past. Sesotec metal detectors help us reach our objective of ecological and economic efficiency and sustainability – from the raw material to the woven sack, and back to the recycled material again."

<![CDATA[Sesotec convince manufacturer of pharmaceutical packaging]]> 2018-01-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/sesotec-metal-detectors-convince-manufacturer-of-pharmaceutical-packaging https://www.sesotec.com/emea/en/resources/blog/sesotec-metal-detectors-convince-manufacturer-of-pharmaceutical-packaging Case Studies

A leading manufacturer of pharmaceutical packaging, e.g. nasal spray containers, operates according to its conviction that its devices have an influence on the health of their users. Quality therefore is extremely important in this field, and this is considered in all phases of the production processes – from product design to production sequences and through to 100 % inline testing. The high quality of the products thus is the result of sophisticated processes and efficient systems.

The significant reduction of customer complaints is the most important indicator for how the company values the observance of quality standards.  Other criteria also are considered with the objective of remedying defects, reducing the number of deviations, and finally increasing customer satisfaction.


Protection of injection moulds and quality assurance of products

One of the packaging manufacturer's plants almost exclusively produces articles for the pharmaceutical industry. About 25 different products are made with a variety of hot runner moulds, with quantities of almost one million per year. Each of these products in turn can comprise up to 27 individual parts that are all injected in the same plant. Some of the large moulds have 48 cavities. All the injection-moulding machines operate in hygienically closed halls.  

Since 2011 the company has equipped its injection-moulding machines with Sesotec metal detectors of type Protector Primus to remove metal contaminations from the plastic granulate. The Protectors make an important contribution to the observance of the company's high quality demands.

With respect to quality standards there were three reasons for the purchasing of metal detectors:

    1. That they avoid machine damage caused by metal particles which e.g. choke cavities and thus lead to expensive repair work.
    2. That there no longer are production losses due to machine downtimes.

    3. That there are no more customer complaints due to contaminated or underinjected products.


How the Protector metal detector works

Metal detectors of the PROTECTOR series are installed directly above the material inlet of injection moulding machines, where they reliably remove metallic contaminations from the slowly descending material column. Apart from outstanding properties such as high sensitivity and space-saving, compact design, the metal detectors of the PROTECTOR series especially are characterised by the "Quick-Valve" reject unit.

When a metal particle is detected a pneumatically controlled piston in this reject unit moves into its reject position, and the rejected material is completely sucked off into a collecting container by means of a Venturi nozzle. The piston then moves back to its pass-through position. Only a minimum of good material is lost in this process, and clogging is impossible.



Result

The project manager of the pharmaceutical packaging manufacturer is highly satisfied with the Sesotec Protector metal detectors: "We are particularly convinced by the high detection accuracy and the high reliability of the systems, and by the ease of operation provided by the Primus control unit."

<![CDATA[Food producer uses Sesotec x-ray inspection systems]]> 2018-01-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/food-producer-uses-x-ray-inspection-systems-to-increase-value-creation-in-production https://www.sesotec.com/emea/en/resources/blog/food-producer-uses-x-ray-inspection-systems-to-increase-value-creation-in-production Case Studies

A big international food group in addition to high quality demands also has committed itself to the fight against food wastage. Following the principle "What men eat must be pure!" they want to ensure perfect product quality so that complete batches of food that may contain contaminations no longer have to be returned and destroyed ("save food!"). Such product recalls are expensive and – what is much more important – damaging to a company's image. In addition to comprehensive inspection procedures in every production stage the measures also include the installation of product inspection systems in the packing lines prior to dispatch.

The systems are used to inspect drink powders and spice blends that are packed in metallised film. They especially search for metal particles but also detect other contaminations. Because of the conductive properties of metallised film inspection cannot be performed with standard metal detectors. To still be able to meet quality demands and prevent food waste the producer decided to use X-ray scanners of the RAYCON range from Sesotec for contaminant inspection. Sesotec is able to meet the high demand specifications with respect to sensitivity and to guarantee swift installation.

Sesotec RAYCON product inspection systems feature sophisticated and reliable X-ray technology and fully meet the quality requirements of the food and packaging industries. The combination with modular conveyor belts allows a customised adaptation to different products and local conditions.

RAYCON product inspection systems provide high-precision inline detection of many contaminants, e.g. magnetic and non-magnetic metals, glass, ceramics, stones, raw bones, and some types of plastics. This also is possible with the type of aluminium packing that is used here. Weight deviations (overweight and underweight) also can be detected. With the "Autolearn" function a new product can be learned in no time at all.

With the "Retrain Region" function the operator for example no longer has to manually make sensitivity settings in order to prevent incorrect separations e.g. due to spice clumps. Due to these and other automated functions machine operators no longer need any expert knowledge, and standstill times for calibration or retooling are reduced.

RAYCON X-ray systems are absolute state-of-the-art with respect to detection possibilities, radiation protection, and system safety. When properly used the X-ray scanner is non-hazardous for operators and products. Radiation levels are many times below the statutory limits. EU directive 1999/2/EC expressly allows X-ray systems for contaminant inspection even for organic food. Innovative X-ray technology offers comprehensive additional benefits for users, which puts the additional costs of purchase and operation into perspective  

Uli Hurzlmeier, Product Manager of Business Unit Food at Sesotec, says: "We were able to demonstrate to our customer a high level of know-how in the field of X-ray inspection, and we were able to prove that we can meet special design and documentation requirements in a very short time. Our expertise and our technical support are unique. And RAYCON also could convince with its price."

A well-attended FAKUMA 2017 is over, and also this year Sesotec convinced trade visitors with the metal separators presented at the trade fair. At the FAKUMA Sesotec not only maintained existing business relations with customers and partners but also was able to establish many new national and international contacts.  The trade fair presence with the new "Purity matters" corporate claim was a complete success. 

At the FAKUMA 2017 Sesotec presented metal separators of the PROTECTOR, RAPID PRO SENSE and GF series. These systems reliably detect and separate magnetic and non-magnetic metal particles even if they are enclosed in the granulate, and they thus ensure the quality of plastic products. Injection moulding machines, extruders, and blow moulding machines are protected against damage and clogging, the output is increased, and the amount of rejects is reduced. Metal separators contribute to the optimisation of processes, to the minimisation of time losses, and to cost savings.  

At this year's FAKUMA trade fair Sesotec for the first time presented OPC UA (Open Platform Communications Unified Architecture) which meets all the requirements concerning Industry 4.0 communications. OPC UA is increasingly being established as a standard. Additional advantages: The criteria of easy operation have been considered, intuitive user interfaces prevent user errors and thus increase process stability. The sequence of operation is safe and follows logical steps. Data and documentation in the system can be quickly accessed.

With respect to the number of visitors and their quality the interpack trade fair, held from 4 to 10 May in Düsseldorf, showed excellent results for Sesotec GmbH. Never before has Sesotec presented so many new and innovative products than at this year's interpack trade fair. RAYCON EX1 X-ray scanner, INTUITY metal detector, and CAPTURA FLOW sorting system demonstrated Sesotec's technology strong points in the competence fields of product inspection and food sorting. Sesotec thus presented itself as a reliable partner for product purity for customers from the food and packaging industry. 

With the new RAYCON EX1 Sesotec provides and easy-to-use entry-level system for the X-ray inspection of packed products, a product segment for which Sesotec before had no systems in its portfolio. Sesotec customers now can have a full-fledged X-ray system in German industry quality at a really fair price. 

The INTUITY metal detector is Sesotec's new flagship in metal detection. It simultaneously inspects food materials with several frequencies and thus reaches extremely high scanning sensitivities, and at the same time offers improved ease of operation with the new INTUITY Control operating panel. 

With its variable use of sensors the CAPTURA FLOW food sorting system offers the advantage of outstanding flexibility. Depending on the type of food that should be sorted the CAPTURA FLOW multi-sensor system can be adapted to the respective sorting requirements. The modular design allows sensor upgrades at any time, which for the customer means that the system is a safe investment for the future.

 

Premiere for slogan and key visual

Sesotec's new Corporate Design also was presented for the first time at the interpack. The new claim "Purity matters" and the key visual of the green diamonds demonstrate Sesotec's brand promises: Perfect purity, reliable quality, long-term partnership, inspiring products, and high sense of responsibility. With this new appearance Sesotec emphasises the company's further development towards a global specialist for solutions in contaminant detection and material sorting. 

Says Oliver Uhrmann, Head of Sales EMEA at Sesotec: "Our strong point is our large product portfolio that allows us to cover all the process steps. From incoming goods inspection through to production and up to packing and outgoing goods inspection, Sesotec provides reliable technologies for all these fields. Our objective is to ensure that our customers achieve highest product purity and quality. Because as our new slogan says: Purity matters."

<![CDATA[Reliable Sesotec sorting systems convince the Swiss]]> 2017-08-29 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/pet-recycling-sorting-of-pet-flakes-with-sorting-systems https://www.sesotec.com/emea/en/resources/blog/pet-recycling-sorting-of-pet-flakes-with-sorting-systems Case Studies About RecyPET

RecyPET AG, established in 1998 has operated Europe’s first bottle-to-bottle PET recycling plant in Fraunfeld, Switzerland, since September 2000. The plant operates with the URRC technology developed by the United Resource Recovery Corporation in the USA  together with Coca-Cola and has an input capacity of approx. 18,000 tonnes per year. A total of five plants in Europe now use this technology.

In Switzerland used beverage bottles are sorted, after collection, in five primary sorting plants by colour and quality, compressed into  bales and delivered to RecyPET AG, and other recycling operators, for processing. RecyPET’s goal is closed loop recycling for  PET beverage bottles. The recyclate produced is used to make a number of products including new PET bottles, food packaging films and other film.


Task

Sesotec supplied a PETMAG metal separator to RecyPET in 2001to separate metal contaminants from PET flakes. As colour sorting was also required, Sesotec, working closely with RecyPET, developed a colour sorter for PET flakes based on a unit originally used in the glass recycling industry. The result was the SPECTRUM range of colour sorters which with double-sided inspection can also separate flakes contaminated with glue residues.


Solution

During 2010 the PETMAG , which had proved a reliable and effective metal separator with minimal maintenance costs, was replaced with  the latest generation VARISORT COMPACT combining metal and colour sensors in the same unit.


Product Advantages

The vibratory feeder and fast inspection belt systems of the VARISORT COMPACT combine the  advantages of chutes and belt systems. For the  first time, for example, rubber pieces can be removed from the material stream which is not the case with chute technology due to friction variation. VARISORT COMPACT with its open construction has the additional benefits over channelled chute systems of being easy to clean and much less prone to blockages caused by larger flakes and irregular shaped product

Even for irregular product or materials which have differing  friction coefficients, the belt feeding system facilitates  pinpoint ejection in free fall at the end of the  feed belt, immediately after inspection. Following inspection, high-speed, precisely timed valves are activated to eject unwanted material from the main product flow into a separate zone for subsequent handling.

VARISORT COMPACT, as the name implies is  characterised by its small footprint  requiring minimum line space. Retrofitting to existing plants and the utilisation of existing chutes and handling systems is easily possible. Using high-resolution sensors and state-of-the-art signal processing technologies allows high detection accuracy and the analysis of up to 500,000 parts per second.  Ejecting product in freefall is precise and repeatable even with high percentages of impurities and individually controlled, closely spaced valves, operating at 500 switching cycles per second ensure effective and efficient operation.


Customer Feedback

For Kornel Büsser, production manager at RecyPET AG, the long-standing cooperation with Sesotec has proven its value: “The reliability and ease of maintenance of the Sesotec units convinced us, together with their performance, particularly in the separation of difficult contaminants.”

<![CDATA[Sesotec With New Managing Director in Italy]]> 2017-08-07 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/sesotec-with-new-managing-director-in-italy https://www.sesotec.com/emea/en/resources/blog/sesotec-with-new-managing-director-in-italy Company

With Andrea Festelli the Sesotec group with effect from 1 April 2017 has recruited a new managing director for the two Italian subsidiaries. The born Genoese studied electrical engineering at the university of Genoa. Before he changed to Sesotec, Festelli for seven years had worked for the Italian subsidiary of the GEA group, where he last held the position of managing director, and before that also was head of the service department. In the course of his professional career he held positions in international sales, marketing, and R&D departments.

One of the major tasks of Andrea Festelli (47) will be to merge the two Italian companies  Sesotec Italy, business segment product inspection, and ASM, business segment food sorting. Says the new managing director about his objectives: "Sesotec successfully develops top technology for contaminant detection and material sorting and is globally present on all the important markets. In the last years Sesotec has achieved remarkable growth, and I am really happy to now be part of this growth. What is particularly interesting for me is the possibility to develop the potential of ASM optical sorters in the product portfolio of the Sesotec group, because with respect to quality and functionality this definitely is a unique offer for our customers. And vice versa we now also can provide ASM customers in Italy with Sesotec product inspection technologies combined with excellent service. A unique opportunity from which both we and our customers will benefit."

Xaver Auer (46), CEO of the Sesotec group: "We really are pleased to now have Andrea Festelli in our group. He has both industry expertise and relevant management experience. The complete merging and integration of our Italian subsidiaries will result in synergies, and the combination of product inspection and material sorting systems offers many advantages for our customers. For us this means that we will move forward even faster on our already successful course in Italy."

<![CDATA[PET Flake Sorting Station Completely Provided by Sesotec]]> 2017-08-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/pet-flake-sorting-station-completely-provided-by-sesotec https://www.sesotec.com/emea/en/resources/blog/pet-flake-sorting-station-completely-provided-by-sesotec Recycling At the Drinktec 2017 trade fair that will be held in Munich from 11 to 15 September 2017, Sesotec GmbH in hall A4, stand 306, for the first time presents itself as a supplier of complete sorting stations for  PET flake recycling. Target customers are recycling companies that are looking for a profitable solution for PET flake recycling and wish to have all the components - from air separator through to sorting machine - from one source. The revised FLAKE PURIFIER+ multi-sensor sorting system will be the trade fair highlight.

Sesotec has more than 20 years of experience in the development and production of sorting machines for PET flake recycling, and based on many corresponding inquiries from customers Sesotec now also offers complete PET flake sorting stations. A complete PET flake sorting line from Sesotec offers many advantages, for example less interfaces and contact persons, and uniform operation of all the line components. Mechanical sorting is perfectly matched to sensor sorting, and both ensure optimal performance.

The FLAKE PURIFIER+ multi-sensor sorting system presented at the trade fair was comprehensively modified and features optimised material infeeding for a more evenly distributed material flow and increased material throughput.  It also allows easier maintenance and integration.  The system's dust-proof design and integrated dust and label extraction connections provide increased efficiency in the recycling process. All Sesotec multi-sensor sorting systems - and of course also the new FLAKE PURIFIER+ - are available with all sensor combinations and in various working widths.

Says Michael Perl, Head of BU Sorting Recycling at Sesotec, about the complete station concept and the new FLAKE PURIFIER+: "Since we received more and more inquiries from customers who wanted to know whether Sesotec also provides complete sorting stations, we decided to satisfy this customer wish. The advantages for customers are obvious: The amount of time and money needed for the coordination of a project is considerably reduced, and the PET flake sorting station operates with maximum profitability. In the modification of the FLAKE PURIFIER multi-sensor sorting system into the new-generation FLAKE PURIFIER+ the wishes of our customers for easier operation and higher material throughput were the decisive factors."

<![CDATA[Sesotec Innovations Benefiting Customers]]> 2017-08-01 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/sesotec-innovations-benefiting-customers https://www.sesotec.com/emea/en/resources/blog/sesotec-innovations-benefiting-customers Company With machines and systems for contaminant detection and material sorting Sesotec GmbH in Schönberg has made it and ranks among the most innovative companies in Germany. In Essen, on 23 June 2017,  Ranga Yogeshwar awarded the TOP 100 seal* to Sesotec.  

What is Sesotec's drive for innovation? First and foremost the customers from the food industry, plastics industry, and recycling industry, who are under a continuously growing pressure to produce their products in highest quality with maximum output and to avoid any waste of resources.  For more than 40 years Sesotec has been developing innovative solutions that contribute to the fulfilling of such requirements.  The company's management actively promotes an innovation-friendly environment: "We listen to our customers, our employees exchange ideas with them on partnership basis, and in the end the result often is a new product idea", says COO Axel Vornhagen. 

In addition to this customer focus, Sesotec also has always been open for new ideas. And this results in innovative products (X-ray systems, metal detectors, metal separators, magnets, and sorting systems) that are characterised by highest detection accuracy and outstanding ease of operation, operate reliably for many years, and are easy to clean and maintain. 

"Our systematic innovation management, from the idea to its practice-relevant checking through to its implementation, is a decisive competitive factor for us", explains Axel Vornhagen. "We invest a lot of time and money in the development of innovations, and we combine the input coming from various sides, from customers and markets as well as from politics and science, with the competence of our employees. We are highly pleased to receive this Top 100 award in recognition of our work."

<![CDATA[Food-PET or Non-Food-PET, that is the Question]]> 2017-02-28 00:00:00 UTC https://www.sesotec.com/emea/en/resources/blog/food-pet-or-non-food-pet-that-is-the-question https://www.sesotec.com/emea/en/resources/blog/food-pet-or-non-food-pet-that-is-the-question Recycling
The Polymark sorting machine made by Sesotec with Polymark detector unit for the detection of UV fluorescence markers on PET bottles.

The "Final Consortium Meeting" of the Polymark project was held at Sesotec GmbH in Schönberg on 7th and 8th February 2017. Polymark was a three-year research project funded by the European Commission that focused on a new technology for the identification and sorting of plastics, particularly PET. The correct detection of plastics and the generation of high-quality secondary raw materials should be further improved. The project involved participants from the complete PET value creation chain. 

The objective of the Polymark project was to increase the level of food-contact-approved recyclate from the PET recycling process by differentiating between PET bottles that were used for food (food bottles) and bottles that did not contain food (non-food bottles). On the one hand marker substances were developed for this purpose that make it possible in the recycling process to efficiently differentiate food-PET bottles from non-food PET bottles. These marker substances are used to encode information about the properties and structure of the PET bottles. 

On the other hand the Polymark project also developed a sensor-based identification system that detects the markers and decodes the information. In a next step the plastic packings are separated in a mechanical sorting process. Sensor technology and mechanical components are integrated in a sorting machine. 

How does a marker substance work?

For the differentiation between food-PET and non-food-PET a bottle type is coated with an invisible UV fluorescence marker. This marking substance is applied to the outside of the bottle or is printed onto the label or the envelope and fluoresces when it is excited by UV light. 

How does sorting work?

In an industrial PET recycling process the bottles usually pass through automated sorting machines that separate the PET flow by colour and plastic type. In the Polymark project this approach was used for the development of a prototype sorting machine that is able to sort food and non-food bottles using a UV fluorescence sensor. Sesotec played a leading role in the development of this sorting system.  

"Our research partners have successfully developed a complete technology package", explains Patrick Peuch of Petcore Europa. "The sorting technology was developed in parallel to the marking technology, and test runs have demonstrated that the markers can be detected by the sorting machine and that the respective bottles can be separated. Economically efficient and profitable high-speed sorting with the result of pure food-PET for bottle-to-bottle recycling thus has become possible." 

The list of Polymark partners includes: Petcore Europa, European Federation of Bottled Waters (EFBW), European Association of Plastics Recycling and Recovery Organisations (EPRO), Plastics Recyclers Europe, UK Health and Environmental Research Institute (HERI), Fraunhofer Institut für Photonische Mikrosysteme (IPMS), Sesotec GmbH, 4PET Recycling BV, Mikrolin Hungary Kft.  and Colormatrix Europe Ltd .
