Wear protection for screw elements and barrels

Extruders and compounders from Coperion can be used highly productively even in difficult applications with aggressive products. A suitable wear protection is the prerequisite for a consistent high product quality.

Considering of the individual requirements and economics, our experts help to find exactly the material which ensures the longest possible life and reliability.

Your advantages
Extended lives of the parts due to wear-protected materials in highly corrosive and highly abrasive applications
Short delivery times for wear-protected elements by special production processes
Optional service
Removing elements from a screw shaft
Barrel bore measurement
Screw elements with high quality wear protection
