21 Extrusion International 5/2020 Keeping Plastic Compounds Free of Metallic Contaminants When it comes toplastics compounding andmasterbatchpro- duction, a certain degree of machine wear and tear is part of doing business. On a semi-regular basis, machines must be re- placed, parts changed out, and facilities retrofitted. While some machine downtime is unavoidable, materials harboringmetallic contaminants can lead to frequent, unplanned stops that incur costly repairs and quality assurance issues. Metal separators play a key role in keeping metallic contaminants out of product streams. Granulate manufacturers and compounders have special re- quirements when it comes to protection against metallic con- taminants. Not only must metal separators in this branch oper- ate with high detection accuracy, but they must also guarantee short cleaning times. Reliable metal separators can increase line availability, ensure product quality, and prevent customer com- plaints. Particularly for compounding and masterbatch produc- tion lines, metal separators can improve profitability. The Whitepaper “Keeping metallic contaminants out of plastic compounds” explores the challenges that metal contamination poses to compoundingandmasterbatchproductionand consid- ers the key features that metal separators must have to provide an adequate solution. TheWhitepaper covers the following topics: • Common sources of metal contaminants in compounding and masterbatch production • The problems caused by metal contaminants • Preventative measures against metallic contaminants •What compounders expect from a metal separator Sesotec GmbH www.sesotec.com The RAPID PRO-SENSE 6 from Sesotec is a metal separator developed with the specific challenges of granulate, compound, and masterbatch producers in mind (Image: Sesotec GmbH) WE DRIVE THE CIRCULAR ECONOMY. Whether it is inhouse, post- consumer or bottle recycling: you can only close loops in a precise and profitable way if machines are perfectly tuned for the respective application. Count on the number 1 technology from EREMA when doing so: over 6000 of our machines and systems produce around 14.5 million tonnes of high-quality pellets like this every year – in a highly efficient and energy-saving way.
