Coperion offers revised version of Kombiplast KP compounding system for PVC

摘要

STUTTGART — The Kombiplast KP compounding system from Coperion, Stuttgart, Germany, is now available in a revised version with considerably improved performance. More compact and more energy-efficient than its predecessor, this new model achieves even better product quality at an even higher throughput rate. The Kombiplast features gentle compounding of heat and shear sensitive plastics. This two-stage compounding system comprises a ZSK twin screw extruder equipped with a ZS-B twin screw side feeder and an ES-A downstream single screw discharge unit which gently builds up sufficient pressure for the subsequent pelletizing operation in the EGR eccentric pelletizer. In its search for a compounding system for PVC, the Italian fittings manufacturer Formatura Iniezione Polimeri S.p.A. (FIP) was very impressed by the performance of the Kombiplast. The first unit of the new, improved series-a KP 62 Mv PLUS/200-has already been put into operation at the FIP facility in Casella, Italy. Featuring a screw diameter of 62 mm, the extrusion system at FIP is being used for the compounding of tailor-made rigid PVC compounds at a throughput rate of up to 1,600 kg/hour.
