From blocking hot runners to crashing extruder screws or breaking blades in shredders, metallic contaminants can cause many problems for plastics processing. We have the right contaminant detectors to prevent damage to machinery and production downtime.
The model of a circular economy presents the plastics processing industry with a compelling framework by which to close the plastics cycle. However, in using recyclate, plastics processors are often confronted with challenges in the form of contaminated materials.
In order to enable the large-scale use of recyclate, contaminants must be avoided and eliminated. The right process technology is critical in this regard. The use of contaminant detectors, flake sorting equipment, and material analysis systems from Sesotec are key to establishing an efficient, profitable circular economy.
Quality assurance is another important factor. Metal particles in the final product are not the only reason for compromised quality. Blockages and tool damage can also result in defects from too little or too much injection of the materials. Metal detectors ultimately help to detect bead wire breaks.

Metal particles made of iron, stainless steel or copper which are hidden among the plastic granules are the most common type of contamination in the plastics-processing industry. They can come from a variety of sources:
Common applications for metal detectors, flake sorting systems and material analysis systems include the following :
As you can see, we support you in all steps of the process. We would be happy to advise you personally to find the right solution for your need together.
How easy is it to install the metal detector in the production line – and

In our white paper, we provide a detailed
outline of the issues, their causes and the necessary countermeasures for
eliminating metal contamination in the plastics processing industry.
The Whitepaper explores the challenges that
metal contamination poses to compounding and masterbatch production and
considers the key features that metal separators must have to provide an
adequate solution.
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.
In the new Sesotec White Paper "Using recycled materials in plastics processing" you will learn about
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.
The quality requirements of the chemical industry are particularly high. Metal detectors play an essential role in the refinement of solids to ensure a consistently high product quality and safety. At the same time, the customers expect quick setup times to achieve high flexibility and efficiency.
Our client in northern Germany employs around 600 people and produces single and double-sided adhesive tapes on production facilities that are among the most advanced worldwide. Raw materials for adhesive tape production can contain tiny metal particles. Even the smallest foreign object that enters production poses a significant risk.
As Plastiques ZD grew, it became necessary to find an environmentally friendly and cost-effective solution for recycling defective parts and production waste. The company turned to the long-time Sesotec partner, MAT Technologic, for a solution.
Viet UC faced the challenge of eliminating metallic contaminants from masterbatch to prevent particles from entering plastic mixtures during production. These contaminants could not only compromise the quality of the final product but also lead to machine downtime and customer complaints.
