Choosing the right custom screw barrel manufacturer is important for stable plasticizing, consistent output and longer equipment service life. A properly designed screw and barrel should match the machine, plastic material and production requirements.

Why Choose a Custom Screw Barrel Manufacturer?

Different plastics require different screw geometries. PE, PP, PVC, PET, PA and recycled plastics have different melting, mixing and wear characteristics. Screw diameter, L/D ratio, compression ratio and flight design should therefore be selected according to the actual application.

Materials and Wear Resistance

For standard applications, 38CrMoAlA nitrided steel provides good hardness and durability. For recycled plastics, glass fiber or high CaCO3 compounds, a bimetallic barrel and wear-resistant alloy screw can significantly improve wear resistance and service life.

Information Needed for a Replacement Screw Barrel

For accurate manufacturing, please provide the machine model, screw diameter, total length, processed material and existing drawing if available. We can manufacture customized screw and barrel sets for extrusion and injection molding machines.
