Conical Twin Screw Barrel

Conical Twin Screw Barrel

The Conical Twin Screw Barrel is a high-performance solution tailored for advanced compounding and extrusion tasks where superior mixing and consistent dispersion are critical. Its conical geometry and specialised mixing zones deliver enhanced shear control and excellent devolatilisation, making it particularly effective for PVC processing and materials that require precise melt homogeneity. Built from durable materials with surface treatments to resist abrasion and corrosion, this barrel maintains steady throughput and reduces material degradation over long runs. Ideal for manufacturers producing PVC pipe, profiles, WPC and CPVC, the conical twin configuration improves heat transfer and process stability while offering flexibility to match various line capacities and formulations.
