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. 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.
conveyor has the task of drawing in the granular plastic, to consistently
convey, to compress and to perfectly homogenise in the output area.
conveyors have an exact geometry, which is suited to the relevant demands and
areas of application.
3-zone standard screw
The standard screw has proven successful in processing most plastics.
We design optimum geometries for specialised applications. Our classic.
3-zone screw with diamond mixing element
This mixing screw ensures homogenous mixing of the molten mass when using Masterbatch or liquid paints.
3-zone screw with spiral mixing element
The spiral mixing element serves as barrier: it supports blending and homogenising the molten mass. Performance can be increased by up to 10%.
The double flight screw
The double flight screw conveyor can be used for processing most plastics. Performance can be increased by up to 15%.
Barrier screw with diamond mixing element
The barrier screw, combined with a mixing element, homogenises
and blends the molten mass with a performance increase up to 25%.
Barrier screw with spiral mixing elements
The barrier screw, combined with a mixing element, homogenises and blends the molten mass with a performance increase up to 25%.
The degassing screw consists of two 3-zone screws fitted one after the other. It serves to process thermoplastics that are still wet, but can never be used for PBT. Drying times can be decreased with this product.
The Thermoset screw works without compression, so that the mass can be heated without friction.
The LSR screw works like a dosing screw, but has a special geometry.
The PVC screw can be supplied with soft or rigid PVC geometry.
The dosing screw serves to transport various materials.
The elastomer screw can be used for injection moulding as well as extrusion.
The extrusion screw is made with different geometries according
to the application.
