The technical solutions for PVC pipe fitting moulding and PVC pipe
fitting mould manufacturing.
PVC is a kind of special material which need special injection
molding process. The basic feature of PVC material:
1. Hard PVC material low MFI
2. PVC with high corrosive
3. PVC with low temperature melting
4. Easy decomposition
Because of above basic features, PVC material has special molding
process. The injection molding machine need precise temperature
controlling and the material can not be heated for a long time. We
can say it is very sensitive with the temperature. Also for this
reason, there is no PVC pipe fitting mould which can use hot runner
Because PVC material’s high corrosive, PVC pipe fitting mould must
need the steel be high quality stainless steel, and also deep
hardened to around HRC50. Since the low MFI, when you make the
runner and injection gate of a PVC pipe fitting mould, we need
special design. For the big volume PVC injection molding, some time
we need a very big runner and injection gate. But the runner can’t
be recycled, what should we do? I think the only way is to reduce
the runner flowing distance to reduce the runner waste.
