Our High Precision Screw Barrel for Extrusion Machine is engineered for superior performance, durability, and accuracy in plastic extrusion applications. Made from high-quality alloy steel (e.g., 38CrMoAl or bimetallic options), it undergoes precise heat treatment and surface nitriding to ensure excellent wear and corrosion resistance.

This screw barrel is suitable for a wide range of materials, including PVC, PE, PP, and more. With optimized design and tight machining tolerances, it ensures stable output, uniform plasticizing, and long service life.

Ideal for film, pipe, profile, and sheet extrusion lines. Custom sizes and designs are available to match your specific machine and processing needs.
