Parallel twin screw & barrel is widely used in plastic extrusion for producing PVC pipes, PE sheets, ABS profiles, and WPC products. Its parallel screw design provides a longer effective working length and stable compression ratio, which improves plasticizing performance, enhances material mixing, and ensures consistent extrusion pressure. This results in high output, uniform melting, and excellent surface quality of extruded products. Compared with conical types, the parallel twin screw barrel is better suited for large-capacity production lines requiring steady output and precise dimensional control. ZY manufactures parallel twin screw & barrel using advanced alloy steels, CNC machining, nitriding, and bimetallic coating. These features guarantee outstanding wear resistance, corrosion protection, and extended service life under demanding operating conditions, making it a reliable solution trusted by customers worldwide.
