A single screw PVC pipe machine is a widely used plastic extrusion machine designed specifically for manufacturing PVC pipes. It features a single rotating screw housed inside a heated barrel, which plays a crucial role in melting, mixing, and pushing the raw PVC material forward through a shaping die. The raw PVC granules or powder are fed into the machine’s hopper, where the screw rotates to convey the material along the barrel. Heat generated from friction and external heaters melts the plastic, which is then mixed uniformly and forced through a die to form pipes of various sizes and shapes.

This machine operates on the principle of single screw extrusion, which is valued for its simplicity, cost-effectiveness, and ability to produce continuous pipe profiles efficiently. Key components include the feed hopper, barrel, screw, and die. The single screw PVC pipe machine is ideal for producing water supply pipes, drainage pipes, and other industrial plastic pipes. Its design ensures consistent melting and precise shaping, resulting in durable, high-quality PVC pipes.
