Large warpage deformation of POM products
Problem Phenomenon
POM products, especially those with holes or asymmetric shapes, warp severely.
Cause Analysis
POM has high crystallinity and large anisotropic shrinkage, plus uneven cooling, causing warpage.
Solution
Uniform mold temperature; optimize gate design to balance melt flow; use glass fiber reinforcement to reduce anisotropy.
Key Takeaway
POM warpage is a direct consequence of its crystalline characteristics.
