The PVC pipe making machine is one of the most widely used production systems in the plastic processing industry. It is designed to produce pipes for water supply, drainage, and electrical conduit applications. Langbo Machinery provides complete PVC pipe extrusion lines that focus on stable operation, consistent quality, and long-term reliability.
A standard PVC pipe production line consists of several major components: twin screw extruder, die head, vacuum calibration tank, cooling tank, haul-off machine, cutting unit, and belling machine. Each unit plays an important role in maintaining product accuracy and production efficiency.
During the extrusion process, PVC powder is first mixed with additives and then fed into the twin screw extruder. Inside the extruder, the material is melted and homogenized under precise temperature and screw speed control. The melt passes through the die head to form a continuous pipe, which is immediately cooled and shaped in the vacuum calibration tank.
The haul-off machine ensures stable traction and uniform pipe wall thickness, while the cutting unit provides precise pipe length. The final step, belling, shapes one end of the pipe for easy connection during installation. Optional equipment such as a laser printer can be integrated for pipe marking and traceability.
Langbo Machinery continues to develop extrusion technologies that enhance automation, energy efficiency, and process stability. Through continuous technical improvement, the company supports the global plastic industry with reliable equipment for modern pipe production.
