We manufacture screws as individual as your plastics. They are performance optimised, highly resistant to wear and corrosion-proof. Our screw production can meet your requirements from Ø 12 – 200 mm, up to a length of 5000 mm. In order to minimise friction, the manufacture of screws for plastic processing machines sets a high standard on the production process as far as finishing precision and surface consistency is concerned.
The screw has the task of drawing in the granular plastic, to continously convey, to compress and to perfectly homogenise it in the output area. Groche screws have an exact geometry, which is suited to the relevant demands and areas of the application.
