HDPE injection molded product warpage — ejection-induced
문제 현상
The product deforms at the moment of ejection and sets as warpage after cooling.
원인 분석
The ejection force plastically deforms the product while it is still hot; insufficient cooling, uneven ejection.
해결 방법
①Extend cooling; ②balance ejection; ③lower the mold temperature; ④optimize the ejector pin layout to rigid areas.
핵심 요약
Ejection deformation = insufficient cooling + uneven ejection.
