PE mold and PPR mold. PVC mold is the three most commonly used molds in various plastic pipe fittings. Each of these three molds has its own characteristics. PE mold, as a pipe fitting mold, has relatively stable physical properties and a relatively wide range of applications. PE mold has the following characteristics.
1: The consumption of pressure is small, and the output of PE mold is relatively high.
2: PE extrusion die can be used as inner and middle layer pipes, and can also be used as outer layer pipes for production. Pipes with different pressure requirements can also be used.
3: When a certain pipe melt temperature is reached, the PE extrusion die makes the melt flow speed reach the expected mechanical uniformity, which can achieve thermal uniformity.
4. The pipes directly used by PE extrusion fittings are various water supply pipes and gas pipes. The pipes produced by PE moulds have strong advantages in connection and connection performance. Due to their high efficiency of moulds, the price of relevant pipes is lower and the quality of products is more reliable.
5: It can realize the size control of multiple diameters in one model, which can save the production cost.
6: PE mold can also use heating thermostatic device in the design of caliber above 200. This thermostatic device mainly includes mold temperature machine and internal heating device, which can produce the best appearance.
PE pipes have developed well in various pipelines, and the sales of relevant PE moulds have also improved significantly.
