FAQ

 

Why is contaminant detection and removal important in the petrochemical industry?

When it comes to producing plastics – one of the most important areas in the petrochemical industry – product purity is a key quality factor. It is necessary above all to eliminate metal pieces and particles, which could otherwise cause damage to machinery when the plastic is processed and create quality issues. As a result, manufacturers of plastics should use machine-based contaminant detectors. It is the only way they can ensure that they are able to consistently deliver granules of perfect quality.

 

What kinds of contaminants could appear?

Metals such as iron, stainless steel and copper very often contaminate plastics. There is a wide range of reasons for this, including:

  • Abrasion and wear from conveyor lines (pipes)
  • Abrasion and wear from machines
  • Broken blades during hot or cold die-face pelletizing
  • Accidental contamination through openings in silos, for example due to staff losing hold of objects


Where do plastics manufacturers use our machines?

It varies. Some manufacturers inspect the granules during production, while others do so after the granules have passed through a screening machine. Other manufacturers use our machines to perform a quality check during the outgoing goods phase, for example directly before filling the granules into big bags, octabins or other similar containers. Contact us – together, we will find the right solution for the set-up of your processes.

White Paper

The circular economy: Challenges and opportunities for Recyclers and plastics processors

The plastics industry is under pressure. Between climate change, excessive consumption of finite resources, and vast amounts of plastic waste in the world’s oceans, plastics are coming to be seen in a different light by politicians, businesses, and consumers alike. Read in our e-book about the most important factors of a functioning circular economy, especially which challenges and opportunities exist for recyclers and plastics processors.

OPC UA for production without machine downtime

SITRAPLAS GmbH is a producer of high-performance engineering plastic compounds. Unplanned downtime is a nightmare for every company, but especially for continuous production facilities. When metal separators are networked with plastic processing machines, the flow of information between machines can be monitored.

Machine protection during PVC granulation

To avoid any metal in the powder, CIPSA wanted to inspect the PVC compounds before they enter the pelletizer. This was to protect the extruder screw from damage and avoid expensive production stops.

How a metal separator saved this plastics manufacturer 75% in maintenance costs and increased output by 20%
While processing virgin glass-filled material together with regrind, the same problem was coming up up over and over again. Metal inclusions were clogging the hot runners of the molds, leading to as many as 10 emergency stops and 2 to 3 costly repairs per month. After careful consideration of the production environment and manufacturing specifications, the metal detection system PROTECTOR 40 was installed along with the magnet system SAFEMAG at the feed hopper of the injection molding machine.
