The formation:
- bubbles appear in the molding process of the product. The air bubbles formed inside the pores or make the product does not fill completely.
Remedy:
- Product design has a thickness in the appropriate location.
- Reposition the injection port.
- 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 screw or reduced performance of the force applied by the deceleration
- If there are air bubbles, you need to put them in areas that can exhaust or add on to the exhaust into words.
