Clean the blocked exhaust holes.
Repair the leakage point.
Increase, expand, or adjust the position/density of the exhaust holes.
Polish and polish to improve demolding.
Minor modifications to the profile (such as reinforcing rib height and fillet size).
Adjust the cooling water circuit (if it affects the uniformity of cooling).
Sometimes it is necessary to modify process parameters (temperature, vacuum degree, time, etc.) to adapt the mold.
Repeated mold testing and repair: until a qualified and stable product is produced. This process may cycle multiple times.
