Large warpage deformation of POM products
Fenómeno del problema
POM products, especially those with holes or asymmetric shapes, warp severely.
Análisis de la causa
POM has high crystallinity and large anisotropic shrinkage, plus uneven cooling, causing warpage.
Solución
Uniform mold temperature; optimize gate design to balance melt flow; use glass fiber reinforcement to reduce anisotropy.
Conclusión clave
POM warpage is a direct consequence of its crystalline characteristics.
