Based in Schwerte-Westhofen near Dortmund, the company will process materials that need a particularly inoffensive treatment such as PET, PA and PC films, non-wovens, filaments, fibres and other plastics. The end product is an agglomerate with excellent flow properties and a high bulk density which has been freed from fines by sifting and screening. The granule size of the end product can be varied according to a customer’s specifications.

Stricker PolyRec opted for the plastcompactor concept developed by Herbold Meckesheim, also of Germany. Due to a short residence time and the special slight sintering process preventing the material from melting, voluminous materials with poor flow properties can be turned into a 100% reusable resource.

In an example of the system’s capabilities, PET bottles are transformed into clean but poorly-flowing flat flakes after washing, separation and drying; but with the plastcompacting process, these flakes are turned into a material with excellent flow properties, appropriate for a trouble-free gravimetrical dosing for film production lines. In a single production step, PET is completely crystallised at the same time.

The Plastcompactor HV 70 at Stricker PolyRec features a 250 kW main drive as well as fully-automatic system control in order to guarantee consistent quality. In designing and developing this turnkey plant, Herbold put special emphasis on the universal application of the machine as well as on quick material change through easy access for cleaning.
