Warpage deformation of PET injection molded parts
Sorun Belirtisi
PET injection molded products warp after demolding, with flatness exceeding the tolerance range.
Neden Analizi
Uneven mold temperature distribution causes inconsistent crystallinity and shrinkage rates in various areas; uneven wall thickness causes cooling differences; molecular orientation is asymmetric.
Çözüm
Equalize mold temperature (within ±3°C); design products with uniform wall thickness; optimize gate position; extend cooling time.
Temel Çıkarım
The root of PET warpage lies in uneven shrinkage.
