Large warpage deformation of POM products
Fenómeno do problema
POM products, especially those with holes or asymmetric shapes, warp severely.
Análise das causas
POM has high crystallinity and large anisotropic shrinkage, plus uneven cooling, causing warpage.
Solução
Uniform mold temperature; optimize gate design to balance melt flow; use glass fiber reinforcement to reduce anisotropy.
Conclusão principal
POM warpage is a direct consequence of its crystalline characteristics.
