Even better performance: Coperion's Kombiplast KP revised

The Kombiplast KP compounding system from Coperion, Stuttgart, Germany, is from now on 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.
These advantages range from the short and definable residence time profile of the material in the extruder process section to the rapid and easy cleaning of the system and the ready adaptation of the system to new tasks. Typical areas of application are the stable, energy-efficient compounding of flexible and rigid PVC, the production of special-purpose compounds such as halogen-free, self-extinguishing formulations for cables (HFFR) or elastomer-based compounds for the production of low, medium and high voltage cables.

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. The PVC compound is then injection-molded into valves for pipe system fittings.
