Molds & Tooling
2 views
Severe warpage deformation of products
Problem Phenomenon
Products warp after demolding and the flatness is out of tolerance
Cause Analysis
Uneven mold temperature, insufficient holding pressure, and asymmetric gates
Solution
Multi-channel mold temperature machines for uniform temperature control, optimize holding pressure, and adjust the gates
Key Takeaway
Warpage control of semi-crystalline materials is difficult
