LDPE Injection Molded Product Deformation - Ejection Type
Problem Phenomenon
The product is pulled and deformed during ejection.
Cause Analysis
LDPE is soft, and ejection with insufficient cooling easily causes plastic deformation.
Solution
①Extend cooling; ②enlarge ejection area; ③lower mold temperature; ④slow down ejection speed.
Key Takeaway
Soft material ejection needs 'fully cooled + large area'.
