Jetting
the reason:
1.Injection speed is too slow or too fast.
2.The injection pressure is too low.
3.The holding time is too long.
4.The mold cooling has been uneven.
5.The temperature near the mold gate is low.
6.The mold surface temperature is too low.
7.The mold gate size is too small.
8.Gate position design is not reasonable.
9.The gate flow is too long.
10.The melt temperature is too low.

Solution:

1.Reduce injection speed (multi-stage injection).
2 Increase the material temperature and increase the mold temperature.
3.Improve the depth of the gate
4.Use fan gate instead.
