What problems should be paid attention to in the process of plastic injection mold design?

1The wall thickness should be as uniform as possible, and the draft angle should be large;

2The transition part should be gradual and smooth transition;

3The gate and runner are as wide as possible, thick and short, and the gate position should be set according to shorten the condensation process, and if necessary, a cold well should be added;

4The surface of the mold should be bright, with low roughness (preferably lower than 0.8;

5There must be enough vent holes and vent slots to discharge the air and gas in the melt in time;

6Except for PET, the wall thickness should not be too thin, generally not less than 1mm.
