PPR Pipe Fitting Mould

The classification of PPR pipe fitting mould

PPR pipe fitting is especially for water supplying piping system, the connection of the fitting with the pipe has 3 different types:

1. glueing type

2. welding type

3. screwing type

Based on the function, we divided the PPR pipe fitting mould into 4 different types:

1. Normal PPR pipe fitting mould

2. Self welding PPR pipe fitting mould

3. PPR pipe fitting mould unscrewing ejection

4. PPR metal over-moulding pipe fitting mould

The technical points for PPR pipe fitting moulds

1. How to avoid the shrinkage marks on the fitting?

2. How to increasing the injection molding speed?

3. How to realize the cavities and cores interchangeable?

4. If there are metal bolt or nuts inserts, how realized the automatic feeding of the metal parts?

5. The injection parameters’ controlling, this is also very important, because of the thick wall of PPR pipe fitting, the pressure holding time, injection pressure, and injection speed… all these affect the dimensions of the ID and OD.
