Plastic pipe machines are specialized equipment designed for the extrusion, shaping, and cutting of plastic pipes. These machines use high-temperature, high-pressure processes to melt plastic granules and mold them into pipes of various diameters and lengths. There are different types of machines based on the material being used, such as polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP). Each of these materials has unique properties that make it suitable for specific applications, thus influencing the design and operation of the respective machines.
