[0002] Plastic pipe polishing is a common surface treatment method used to improve the appearance and texture of plastic pipes. Usually, plastic pipes may have some unevenness, burrs or flaws during the manufacturing process, and polishing can effectively remove these problems and make the surface smoother and more uniform; polishing of plastic pipes can not only improve the appearance quality, but also reduce surface friction and increase its wear resistance. In addition, polished plastic pipes are easier to carry out subsequent painting, printing or other decoration processes, thereby meeting the needs of different application fields.
