As one of the common plastic machines, the composite pipe production line needs regular maintenance, which should also be carried out according to certain procedures and corresponding requirements of equipment safety and technical performance. This is conducive to the operation of equipment and can ......
Read MorePipe cutting methods can be generally divided into two kinds: manual cutting and automatic cutting. When the diameter of pipe is small (within 50 mm), many manufacturers will use saw to cut by hand in many cases. But now, in order to improve the production efficiency and ensure the length accuracy o......
Read MorePlastic extruder will inevitably have some quality problems in the production of polyvinyl chloride (PVC) double wall corrugated pipe, in addition to the problems of equipment itself, there are still very cases of quality problems. We can ignore the problems caused by equipment, because generally, t......
Read MoreIn most extruders, the screw speed is changed by adjusting the motor speed. The drive motor usually rotates at a full speed of about 1750rpm, which is too fast for an extrusion screw. If it rotates at such a fast speed, too much friction heat will be generated, and the uniform and well stirred melt ......
Read MoreThe barrel includes a screw, which rotates in the barrel. When the screw rotates and the thread is pushed, the heat is transmitted to the material by heating outside the barrel. In addition, the volume of the thread is gradually reduced, so that the material is evenly mixed and plasticized into a mo......
Read MoreThe calibration sleeve is a component that assists the cooling and shaping of plastic pipes in the extrusion production of plastic pipes. It is installed at the front end of the vacuum calibration machine. After the pipe comes out of the mold, it enters the vacuum tank and spray cooling tank for fur......
