Omega offers customization of extrusion barrels made using different materials. For a single screw extruder, we offer whole extrusion barrels and barrel liners. Not only do we recommend the best barrel materials to meet different manufacturing conditions, but we are also excellent at manufacturing bimetal barrels with a higher wear resistance and longer working life.
The bimetal barrel has a basic body material with normal strength, but there are specific alloy layers on the surface of the bore in barrel. We can change the thickness and toughness of this layer, and make it wear resistant or corrosion resistant, or both wear resistant and corrosion resistant. The basic body material and corresponding alloy layer form a whole, called bimetal barrel.

Technique & Process Equipments for making Barrel
The chief leading member of our Shanghai Omega Group is the first creator in the bimetallic technology in the last century 80 's in China, researching and developing different kinds of alloy protective coatings for the bimetallic barrel and bimetallic screw. After years of constant exploration and improving, it’s proven that the bimetallic barrel and bimetallic screw protected by different kinds of wear-resistant and corrosion-resistant alloy feature excellent operation life and unmatched cost-performance. Our research and development is highly praised by the industry, and has made a significant contribution to the industry development.
