Common injection molding product defects and solutions-4

shrink

the reason
1.The holding pressure is too low.
2.The holding time is too short.
3.Injection speed is too fast or too slow.
4.The mold surface temperature is too high.
5.The water size is too small.
6.The flow path design process is too long.
7.The bone thickness of the product is too thick.
8.The melt temperature is too high.

Solution:

1.Improve the filling and holding pressure.
2.Increase the holding time.
3. Reduce the mold temperature.
4.Appropriate injection speed.
5.Reduce the material temperature.
6.Check if the pad is sufficient.

7.Measure the mold surface temperature.
