Note: if any metal insert molding products, need to preheat insert: metal insert preheating temperature: 130 ~ 140 ℃, time: constant temperature for 1 hour

2. Injection molding process

Mold temperature: 120 ~ 150 ℃ (can be set according to the product structure situation)

Cylinder temperature:

The front:290~300℃

In the middle:300~320℃

The last period:310~330℃

Nozzle:310~330℃

Injection pressure:80~150MPa(70-95%)

Injection speed: medium speed ~ high speed.

Pressure holding pressure:30-70MPa(20-45%)

Meterthe residual amount is set 5-10mm.

Loose back: 3-5 mm

Screw rotation speed:50-120rpm
