manufacturers of vehicle tyres and other products made out of rubber, the
consequences of pieces of metal accidentally making their way into the
production process can quickly become costly. Damage and downtime are potential
risks, but we have the right metal detection systems to minimise them.
Different rubber formulations contain varying amounts of carbon black, oxides and activators. As a result, there are large variations in intrinsic conductivity. Other considerations that come into play include the operational environment featuring many different machines and the extremely slow conveyor speed in many cases. These factors make it difficult to reliably detect pieces of metal while avoiding false alarms.Sesotec metal detectors therefore feature state-of-the-art detection technology with the highest degree of scanning sensitivity. In addition, they can actively block ambient interference and compensate for the material’s intrinsic conductivity through saved settings for different rubber formulations. Multi-frequency technology makes it possible to easily inspect compound formulations with a high degree of intrinsic conductivity as well.
Metals of any kind are the contaminants most frequently found in the rubber and tyre industry. They can come from a variety of sources:
The most common applications include the following:

metal contamination poses to compounding and masterbatch production and

Separately purchased recyclate often contains various different polymers as well as metal contaminants such as aluminum, brass, and stainless steel. Learn in our Case Study how Sitraplas has solved this problem.
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.
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.
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.
