Improvement measures
The following is for reference:
1. Except for the slight water mark near the gate, the other parts have water marks throughout, and the mold temperature may not meet the requirements as a whole.
Check whether the material head is too dry (you can cut the material head to see if the material is over enough)
2. There are many reasons why the mold temperature cannot be reached:
The master of the machine is too slow to open a few modes in a minute
Without the cooling water of the sprue sleeve, it can’t be fast
It is a cold mold product
3. Suggestion
Continue to increase the mold temperature and see product changes
Properly elongated gate
Re-opening the mold can consider entering at one end (and multiple out at one time)
Tips
About watermark:
The water lines are large and small.
If it is a local water mark, consider the adjustment of the runner or slag bag for improvement;
But if it is a large area of water lines, it means that the overall mold temperature is insufficient or the mold temperature fluctuates too much (see the yield of water lines in detail).
