Our products

Product category: Screws


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.

The screw-tip-set is the heart of the plasticizing unit.

Screw-tip-sets must close safely and should allow a constant mass cushion in order to guarantee reliable and even dosing.

There are no good or bad screw-tip-sets, but only suitable and unsuitable ones as far as manufacturing quality is concerned.

Screw-tip-sets by Groche aim to achieve minimal wear and a long service life.

We guarantee:

▪ agreed product solutions
▪ short delivery times
▪ reliable service

Product category: Barrels


We manufacture cylinders in high wear and corrosion resistance designs from 12 mm to 200 mm in diameter, up to a length of 5000 mm.

The cylinder’s tasks are static. It undergoes high levels of pressure and tension when thermally loaded. Borehole surfaces must resist wear and corrosion caused by the plastics.

The cylinder feeding zone can be optimised for each individual application.

Our product range comprises of thermoplastic, thermoset plastics, silicone and elastomer processing in the appropriate optimum qualities.
