Our Conical Twin Screw Barrel for WPC (Wood Plastic Composite) is specially designed for high-output and stable extrusion of WPC materials. Made from high-quality alloy steel such as 38CrMoAl, it is treated with nitriding or bimetallic coating for excellent wear and corrosion resistance.

The conical twin-screw structure ensures strong shear, efficient mixing, and uniform plasticizing of wood fiber and thermoplastics like PVC or PE. Ideal for decking, panels, and profile extrusion.

Custom dimensions and designs are available to fit your specific machine and production needs.
