Many people buy injection molding machine When asked, what factors determine the molding of injection molding machines? Next, Liansheng Precision will introduce to you:

1、 For injection molding process, attention should be paid to the changes of pressure and temperature

(1) The injection pressure is too low, which is prone to short shots;

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

(3) When the temperature decreases, 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 molten material to fill the cavity;

(5) If the temperature is too high, the plastic is easy to degrade;

2、 Set pressure switching position

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

3、 Set melt temperature

Each plastic material corresponds to the corresponding melt temperature, and the specific value can be inquired from the material supplier.

4、 Set 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.
