LCP Sticking to Mold and Demolding Difficulty
Fenómeno do problema
【Problem Phenomenon】LCP thin-wall products locally adhere to the cavity, with whitening, ejector puncture or deformation during ejection
Análise das causas
For thin-wall deep-cavity products with large gripping force, insufficient draft angle or wrong polishing direction, plus local vacuum adhesion and unbalanced ejection, cause mold sticking; Celanese troubleshooting lists a special item on mold sticking
Solução
Increase the draft angle and polish along the demolding direction; increase the number of ejector pins to balance the ejection force; check cavity vacuum adhesion and provide air intake; appropriately extend cooling to reduce gripping force
Conclusão principal
Mold sticking of LCP thin-wall parts is mainly caused by mold draft angle, polishing and ejection balance; 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
