Our xing yin plastic manufacturing plant has a good reputation all over the world in terms of the quality of the PVC water supply pipes produced by our xing yin plastic manufacturing plant. Because we treat it with a rigorous attitude and careful operation during production, let me introduce you to pay attention to the production and operation of water pipes.
Operating instructions for the production of PVC water supply pipes
In order to ensure that the quality of the PVC water supply pipe fittings produced has no problems and can also improve the production efficiency, it is required that the extruder must be used correctly.
Because of the characteristics of the conical screw of the extruder, the feeding section has a larger diameter, and the heat transfer area and sheer speed of the material are relatively large, which is conducive to the plasticization of pipes and pipes. The small diameter of the screw in the metering section reduces the heat transfer area and The sheer speed of the melt enables the melt to be extruded at a lower temperature.
When the screw rotates in the barrel, it plasticizes the mixture of PVC-U water supply pipe fittings and faces the machine head, so as to achieve compaction, melting, mixing, and homogenization; and the purpose of exhausting and dewatering is completed. Feeding equipment and screw drive equipment adopt frequency conversion speed regulation, which can complete synchronous speed regulation;
The extrusion die head part is the key part of the molding of PVC water supply pipe fittings. It takes the compacted, melted and kneaded and homogenized PVC and the follow-up materials are passed through the screw to face the die, and the product is shaped and quality controlled.
