Análisis de la causa
Excessive holding pressure and large internal stress, insufficient draft angle, improper polishing; PC has strong rigid gripping force; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solución
Reduce the holding pressure; check the draft angle and polishing; balanced ejection; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Conclusión clave
For PC mold sticking, first reduce the holding pressure, then the draft angle and polishing; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
