We manufacture screw conveyors 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.
Groche Technik manufactures the central components for your plasticizing unit.
We make various nozzles, covers, mixing elements and specialised nozzles for you and the special demands of processing plastics.
The HVOF method is a process for refinement of screw conveyors. The screw conveyors made of tool steel are roughened to start. A gas mix is now ignited with a special gun, which causes the metallic powder particles to melt, and they are shot onto the screw conveyor at a speed of 750m/s.
