PP2R is a kind of thermoplastics. The main pipe processing method is Injection molding.
Processing PP2R pieces of the plasticinjection machine from 125G to 2500G differ.
Then point out some of the important information about PP2R processing.

PP2R Pipe Mould temperature control: Feeding section temperature: 180~200℃. Nozzle temperature: 200~220℃.

Ⅰ、Pressure control:
◆Injection pressure also divided into three levels.
◆Holding pressure: Because the product walls thicker, the product after the mold can keep not deformation.
The size of pressure and the press time is very important.
◆The pressure setting of the consideration of factors: ①according to mold poured crossing effective area size。
② should consideration of the temperature and other factors.
Ⅱ、PP2R Pipe Mould manufacturing:

● Gating system: consist of runner set, points of water, the import material composition.
● Core and Cavity: PP2R Fitting product appearance all use inferior smooth processing, in order to ensure that the product appearance.

● PP2R Fitting Mould is generally used to release the stripper.

● PP2R material ：The core general use of the steel material about 40Cr, P20, etc. Use life about 10-300000 model
