Rubber Processing Screw Barrel Injection Molding Or Extrusion

Rubber Processing Screw Barrel Injection Molding or Extrusion

 

Rubber processing screw barrel sets are designed to withstand the high temperatures and pressures involved in the processing of these materials. They are typically made from high-quality alloy steel and coated with wear-resistant materials such as tungsten carbide or ceramic to ensure durability and long-term use.

 

Ningbo DW Plastics Machinery manufactures bimetallic masticating barrels and liners for all types of rubber injection molding, cold and hot feed rubber twin and single screw extrusion machinery. Our products are found worldwide operating in mild to severe abrasion and corrosion wear environments.
