PVC pipe fitting Mould ( for high pressure and low pressure = for water supplying and water discharging)
1. CPVC pipe fitting mould for high pressure.
2. UPVC pipe fitting mould for water drainage
3. PVC belling pipe fitting mould( with collapsible cores for pressure water supply).
4. Electricity cable pipe fitting mould, built in-wall various PVC pipe fittings.
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
The most essential points to be noted before selecting the right steel for these moulds are understanding the complexity of the part, material flow, doing the structural analysis and providing a suitable ejection system for the product. Many times it is important to do the mould flow analysis before mould designing and planning the assembly and functionality of the mould.
PVC pipe fitting Mould structure
Every industrial product mould needs to achieve the exact part dimensions and part weights hence it is important to consider the shrinkage of the material after moulding. For this the gating system, cooling lines, quality of hot runners play an important role in achieving a good end product.
Mould cooling time in pipe fitting moulds is the biggest factor to be considered for high end productions. Many mould makers use regular cooling designs for these product, however customized cooling systems need to be designed for every part separately. Optimization of cooling process can save many thousand dollars in the overall cycle period during production. Even cooling lines are considered as the backbone of the product function in many cases of industrial category especially in the cases of multi cavity complex moulds.
Hardness control & Quality
Parts made from PVC require steel such as 3Cr13 (type of a stainless steel) from China which helps the material flow well without sticking especially in cases of hollow products such as pipe fittings. This mould steel does not require chrome plating or polish and the hardness is strong enough to produce more than 0.5 millions shots.
