원인 분석
POM has large crystallization shrinkage and tightly grips the core; too low mold temperature causes faster shrinkage and tighter grip; insufficient draft.
해결 방법
①Increase mold temperature; ②check and increase draft; ③reduce holding pressure; ④polish the core.
핵심 요약
POM mold sticking = crystallization gripping force, and increasing mold temperature is the key.
