Coperion: New Compounding Test Center in Stuttgart
Following an intensive planning and construction phase, Coperion GmbH, Stuttgart, Germany, recently opened a new compounding test center. The test center is equipped with 20 different ZSK extruders with throughput rates ranging from 10 to 3,000 kg/hr. It replaces the existing test center and serves to provide customers with the optimum system design of a compounding line – under close–to-production conditions – and to carry out tests aimed at further developing processes and testing of new machine parts.
With a footprint of 2,700 m² and floorspace of 4,500 m² on three levels, the test center design permits the installation of trial set-ups corresponding exactly to actual production conditions. Quality control tests and analyses are carried out in the analytical laboratory located within the test center. The test center will accommodate up to 100 customer trials per year. Depending on the objective of the trial, the throughput rate ranges from laboratory requirement through to medium production runs.
Besides the new test center in Stuttgart, Coperion also has two other compounding test centers. One of them is located in Ramsey, NJ/USA, and is equipped with several ZSK extruders for customer trials. The newly built test center in Nanjing, China, is equipped with two STS compounders. The company also operates a bulk material test center in Weingarten,Germany. This test center network is the only one in the world which covers the entire process chain for the compounding of plastics.
