We manufacture screws as individually as plastics. They are performance optimised, highly resistant to wear and tear and corrosion-proof. Our screw production can fulfil your requirements from 12 mm to 140 mm in diameter up to a length of 5000 mm. The manufacture of screws for plastic injection moulding machines sets increased demands on the production process as far as finishing precision and surface consistency is concerned, in order to minimise friction.
The screw has the task of drawing in the granular plastic, to continously convey, to compress and to perfectly homogenise in the output area.
Groche screws have an exact geometry, which is suited to the relevant demands and areas of application.
