- Product design has a thickness in the appropriate location.
- Reposition the gate.
- Reduce injection speed, because if sprayed at high speed, the air bubbles do not escape.
- However, we must first optimize exhaust system, then consider lowering the injection speed.
- reduce the pressure loss of the screw or reduced pressure by reducing the speed (especially when gas bubbles are formed near the gate).
- If there are air bubbles, you need to put them in areas that can exhaust or add on to the exhaust into words.
