Product Description
Our twin screw barrel liners are designed to extend the working life of your extruder barrels
by providing exceptional wear and corrosion resistance. Made from advanced materials such as HIP alloy, tool steel, or bimetal composites, these liners are ideal for demanding processing environments with
abrasive or corrosive fillers, such as glass fiber, calcium carbonate, or flame retardants. Available for a wide range of extruder models—including Coperion,
Leistritz, and others—our liners feature tight machining tolerances and customized inner diameters from 15.6mm to 200mm. Whether you're processing engineering
plastics or recycling materials, our liners ensure long-lasting protection and reduced maintenance downtime.
We can satisfy your different material needs:
According to appearance design,Closed Barrel,Feeder Barrel,Side Feeder Barrel,Venting Barrel,Combi
Barrel.
According to Materical,
-For wear application:C liner;Cr26；Cr12MoV;W6Mo5Cr4V2;
-For corrosion application:Nonliner;
-For wear and corrosion application:Nickel based
alloy;WR13,SAM26etc.
Through the understanding of customers,recommend the most valuable
material.
