ASA Demolding Mold Sticking
Fenómeno del problema
【Problem Phenomenon】ASA products stick to mold and get pulled damaged, ejection deformation
Análisis de la causa
Large shrink-fit force, insufficient draft angle, wrong cavity polishing direction or excessive holding pressure cause mold sticking; deep-cavity thin-walled parts high incidence; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solución
Check draft angle and polishing direction; reduce holding pressure; increase ejection area to balance ejection force; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
ASA mold sticking first check draft angle and polishing, excessive holding pressure also causes mold sticking; after confirming effectiveness, fix 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
