Parallel twin screw & barrel is a widely used component in plastic extrusion, suitable for producing PVC, PE, 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, el 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.
Our products undergo strict quality control at every stage, from raw material inspection to final testing. With over 20 years of experience and international certifications including CE, TÜV, BSI, and UKAS, Intai provides customers with reliable extrusion solutions trusted in more than 20 countries.
