High-efficiency conical twin-screw barrel for PVC, PE, PP pipe and profile extrusion. Excellent plasticizing, high torque, stable output.
Vanwell conical twin screw barrels are engineered for PVC pipe extrusion lines, featuring a tapered screw design that provides high torque transmission and superior plasticizing performance. The conical geometry ensures even material compression, uniform melt quality, and stable production output.
Available in a full range of sizes from small extrusion lines (Ø20/25mm) to large industrial pipes (Ø80/156mm). Suitable for PVC-U, PE, PP, and multi-layer composite pipes. Bimetal barrel lining and nitrided screws ensure long life even with highly abrasive PVC compounds.
Tapered screw geometry provides progressive compression and uniform melting.
Strong feeding section handles high viscosity PVC compounds efficiently.
Wear-resistant iron-based alloy lining extends barrel life in abrasive conditions.
Specifically designed for rigid PVC-U pipe with excellent thermal stability.
Fits Braess, Leistritz, Jinming, and other standard conical twin-screw lines.
Consistent melt pressure and flow rate for smooth pipe production.
Optimized screw clearance reduces motor load and energy consumption.
Also suitable for PE, PP, and multi-layer composite pipe production.
