PVC pipe fitting mould (high pressure and low pressure = water supply and drainage)
1. High pressure CPVC pipe fitting mould.
2. UPVC pipe fitting mould for drainage
3. PVC elbow fitting mold (foldable core with pressure water supply).
Power cable pipe mold, built-in all kinds of PVC pipe.
PVC pipe molding and PVC pipe mold manufacturing technology. PVC is a kind of special material which needs special injection molding process.
The basic characteristics of PVC materials are as follows
1. Low MFI of rigid PVC material
2. High corrosive PVC
3. Low temperature melting PVC
4. Easy to decompose
Due to the above basic characteristics, PVC material adopts special PVC molding process. The injection molding machine needs precise temperature control, and the material cannot be heated for a long time. We can say it's very temperature sensitive. Also because there is no PVC pipe mold can use hot runner system.
Due to the high corrosiveness of PVC material, the steel of PVC pipe fitting mould must be made of high quality stainless steel and hardened to HRC50. Due to the low MFI, when you make the runner and injection gate of PVC pipe mold, we need special design. For mass PVC injection molding, there was a time when we needed a very large runner and injection gate. But runners can't recycle. What should we do? I think the only way is to reduce runners' flow distance to reduce runners' waste.
