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. Intai 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.

Parallel twin screw & barrel is a widely used component in plastic extrusion, suitable for producing PVC, پیئ, ABS, and WPC products. With its parallel design, the screw offers strong feeding ability, stable plasticizing, and excellent mixing performance. These features ensure consistent extrusion pressure, high output, and reliable quality of finished products.

Compared with conical designs, the parallel twin screw barrel provides longer effective screw length and a more balanced structure. This design is ideal for applications requiring large capacity and uniform melting of raw materials. It helps manufacturers achieve efficient production while maintaining dimensional accuracy and surface quality of extruded pipes, sheets, and profiles.

Intai manufactures parallel twin screw barrels using alloy steels, CNC machining, and advanced surface treatments such as nitriding and bimetallic coating. These processes improve wear resistance and corrosion protection, extending the service life of the screw barrel under demanding extrusion conditions.
