Equipment for Polymer Processing

The focus at the polymer processing plant lies on the processing of fiber-reinforced thermoplastics. Our equipment there includes twin screw extruders, a system for the production of UD Tapes, injection molding machines, as well as two Injection Molding Compounders. In the case of the last mentioned machines both work steps (injection molding and the compounding process) occur in one step. The facility’s throughput, tool size and degree of automation allow the serial production of components, for example for sampling purposes.
