WEBER extrusion
Wear protection packages

WEBER basic

Screw and barrel nitrided


Technical Support

Screws and barrels for standard applications made of nitrided steel. High surface hardnesses can be achieved by the choice of nitriding steel. We recommend post-nitriding for regeneration above a certain wear limit to increase the service life of the screw and barrel.

Recommended for the following applications: Tubes and profiles with low filler contents. Low protection against wear.

WEBER advanced

Screw and barrel hardened & nitrided


Technical Support

Screws and barrels made of high quality hot working steel. For maximum hardening depth, screws and barrels are hardened and then nitrided. Compared to nitrided steel, a higher surface hardness with good corrosion resistance can be achieved through the choice of base material. We recommend post-nitriding for regeneration above a certain wear limit in order to increase the service life of the screw and barrel.

Recommended for the following applications: Window profiles with high titanium dioxide content, pipes with higher filler contents or regranulate. For profiles with abrasive fillers.

WEBER premium

Screw armoured & nitrided, WC-bimetallic barrel


Technical Support

A combination of armoured screw and tungsten carbide bimetallic barrel for maximum wear protection. By selecting the right filler material, a particularly well-matched friction pairing can be achieved. The outer diameter of the screw is thus protected against high abrasion wear. Above a certain wear limit, we recommend regeneration by means of multi-layer build-up welding and subsequent re-nitriding.

Recommended for the following applications: Our premium solution for high demands, suitable for sheets (LVT), window profiles with regenerated granulate as well as extrudates with abrasive fillers.

WEBER special

Screw armoured & WC-coated, WC-bimetallic barrel 


Technical Support

A combination of armoured screw and tungsten carbide bimetallic barrel for maximum wear protection. By choosing the right hardfacing material, a particularly well-matched friction pairing can be achieved. The flight surface of the screw is thus protected against high abrasion wear. In addition, maximum wear protection is achieved on the screw flank and core. The tungsten carbide coating can be used over the entire screw length or only in certain areas. Above a certain wear limit, we recommend regeneration by multi-layer build-up welding and subsequent recoating.

Recommended for the following applications: For special applications such as wood plastic compounds. Suitable for extrudates with a very high content of abrasive fillers, for example for the extrusion of pencils.
