Introduce the forming of PPR pipe fittings

Plasticization is the core technology in the processing of PPR pipes, which will affect the quality of products. In the process of equipment, we must grasp the technical methods.

In order to improve the fluidity and prevent the occurrence of bubbles, plastics can be dry in advance, the casting system of the mould should be short and thick, the section of the gate should be large, there should be no dead angle, and the mould should be cooled. Because of the corrosiveness and fluidity of PPR pipe fittings, it is better to select special equipment and die. All products are required to participate in different kinds and quantities of additives as required. It should be noted that it is easier to differentiate with steel and copper at 200 C temperature, and the scale of escaping corrosive stimulus gas forming temperature is small. When choosing the nozzle of screw injection machine, the aperture should be large to prevent dead angle stagnation, without inserts, and if there are inserts, preheat them.

When installing PPR pipe fittings, pipe cards should be set according to different pipe diameters and requirements, the direction should be correct, the burial should be smooth, the touch between pipe cards and pipes should be tight, but the appearance should not be harmed.
