The production process of plastic pipe extrusion should be selected according to the type and size of plastic pipe. Generally, plastic extruders are used to extrude products. However, plastic materials and types of plastic pipes are different, so the principle of molding in production is different. ......
Read MorePE three-layer co-extrusion pipe equipment production line is a production and manufacturing line of plastic pipes using vacuum sizing technology. However, if the technology is not mature, the processing is rough, and the process is not refined, some unexpected failures may occur, such as no vacuum.......
Read MoreIn most extruders, the screw speed changes by adjusting the motor speed. The drive motor usually rotates at full speed of about 1750 rpm, which is too fast for an extruder screw. If it rotates at such a fast speed, too much friction heat will be generated, and the retention time of plastic is too sh......
Read MoreFeeding area of plastic extruder: the fixed groove depth of screw groove, which is responsible for preheating, plastic solid conveying and extrusion. It must be ensured that the plastic starts to melt at the end of the feeding section - that is, it must be preheated to the melting point. The general......
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......
