PVC pipe manufacturing machine is a mechanical equipment used for producing PVC (polyvinyl chloride) pipes. PVC pipes are widely used in modern construction, water conservancy engineering, agricultural irrigation, and other fields. PVC pipe manufacturing machines usually consist of extruders, molds, cooling systems, traction machines, and cutting machines. The extruder is the core part of the PVC pipe manufacturing machine, and its main function is to heat PVC particles or powder to a molten state, and push them into the mold through the rotation of the screw.
