PVC single screw barrel is a professional core component designed for PVC plastic processing. Adopting advanced nitrided and bimetallic technology, it features excellent corrosion resistance and wear resistance, effectively avoiding PVC decomposition, carbonization and material sticking during processing. Precisely matched with single screw extruders, it ensures stable plasticization, uniform melting and high production efficiency, suitable for global PVC processing manufacturers.

Application

The PVC single screw barrel is widely applied in plastic extrusion machine for PVC processing, including PVC pipe, profile, sheet, pipe fitting extrusion and PVC granulation, meeting the needs of construction, decoration and packaging industries.
