Coperion: New twin screw extruder for Ensinger

The German company Ensinger GmbH has placed an order with Coperion GmbH, Stuttgart/Germany, formerly Werner & Pfleiderer, for a twin screw extruder of the new ZSK Mc18 series. The compounder is equipped with 45 mm diameter screws, two ZS-B side feeders and one ZS-EG twin screw side devolatilization unit.

Ensinger is specialized in the production of compounds, semi-finished products, profiles and finished products in high performance engineering plastics and will be using the new compounder at its main factory at Nufringen/Germany for the production of high-grade compounds reinforced, for example, with glass or carbon fibres.

Typical matrix materials are polyamide (PA), polyether ether ketone (PEEK) or polyethylene terephthalate (PET). The ordered ZSK 45 Mc18 is a high-temperature version capable of approximately 50% higher heating capacity, which means that the required high processing temperatures of more than 350 °C - especially for the processing of PEEK - can be reliably achieved and maintained with absolute precision, announced the manufacturer.
