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

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

2. The transition part should be gradually and smoothly transitioned to prevent sharp corners;

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

4. The surface of the mold should be smooth and clean, with low roughness (preferably low 0.8);

5. Exhaust holes and grooves must be sufficient to discharge the air and gas in the melt in a timely manner;

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