Cylinder temperature:

The front: 280 ~ 290 ℃

In the middle: 290 ~ 300 ℃

The last period: 300 ~ 310 ℃

Nozzle: 300 ~ 310 ℃

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

Injection speed: medium speed ~ high speed.

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

Meter: the residual amount is set 5-10mm.

Loose back: 3-5 mm

Screw rotation speed: 50-120rpm.

Back pressure: 0.2-5MPa.

Injection molding time: according to the size of the parts, when the mold is filled with mold, and the surface is basically cooling is good.

 

3. Post-processing technology: determined by the size of the parts.
