>> When our customers ask us to develop a new product and the appropriate compounding system, it’s the greatest motivation one could have: Giving you exactly what is best for you.

Processing of engineering plastics

Toothbrushes, plastics panels for cars, anchor bolts, cable insulations, shoe soles, gaskets, window profiles, packagings – the list of ordinary everyday products whose raw materials were processed with Coperion machines or systems from Coperion, could be continued endlessly.

The co-rotating ZSK twin screw extruders from Coperion, formerly Werner & Pfleiderer, are the world’s most frequently used extruders for the production of engineering plastics. Every one of our systems features smoothly interacting process steps and gentle handling of the product with maximum productivity.

The quality of the end product is always the center of focus of our compounding plants: From dosing, through raw materials feeding, conveying, melting, dispersing, homogenizing, devolatilizing, pressure build-up, filtering and pelletizing, we adapt every process step exactly to the requirements of the plastic. This makes the processing plants constructed around the ZSK twin screw extruder the optimal solution for the production of engineering plastics – from simple coloring and alloying of base polymers to the mixing of organic and inorganic filling and reinforcement materials.
