LLDPE '2079851475616104452 warpage
Problem Phenomenon
Deformation of LLDPE injection molded parts.
Cause Analysis
High shrinkage + uneven cooling; LLDPE crystallinity is lower than LDPE but shrinkage is still large.
Solution
①Balance mold temperature; ②extend cooling; ③uniform wall thickness; ④reduce holding pressure.
Key Takeaway
2079851475616104452 deformation = cooling balance.
