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