What factors determine the injection molding process?

1. Injection molding process, you need to pay attention to the changes in pressure and temperature

(1) If the injection pressure is too low, short shots are likely to occur;

(2) If the injection pressure is too high, the product is likely to have flash.

(3) When the temperature drops, the pressure needs to be increased to ensure that the plastic is injected into the cavity;

(4) When the temperature is too low, it is difficult for the molten material to fill the cavity;

(5) When the temperature is too high, the plastic is easily degraded;

2. Set the pressure switching position

Please note that the pressure switching point determines the stroke of the piston.

3. Set the melt temperature

Each plastic material corresponds to a corresponding melt temperature. You can ask the material supplier for the specific value.

4. Set the mold temperature

Pay attention to ensure that the temperature difference between the front mold and the rear mold of the mold does not exceed 20℃ of the melt temperature.
