Problem Phenomenon
Trapped air problems.
Cause Analysis
Poor venting; fast crystallization and fast filling require more venting.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Improve venting; ②focus on the end; ③regular cleaning; ④reduce speed to assist.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Venting is a mandatory item in mold design.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a troubleshooting reference for subsequent similar problems
