Solución
①Appropriately increase mold temperature; ②increase draft angle; ③polish the cavity; ④balanced ejection.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Solve mold sticking from both the gripping and structure ends.; 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 similar problems in the future
