Product severe warpage deformation
ظاهرة المشكلة
The product bends, twists or dishes, and cannot be solved after multiple process adjustments
تحليل الأسباب
Fiber orientation causes anisotropic shrinkage (small longitudinally, large transversely); uneven mold cooling causes temperature gradient stress; asymmetric geometric structure constraints of the product
الحل
Use mold temperature control to achieve uniform cooling; reduce injection and holding pressure to reduce orientation; anneal the product after demolding to release internal stress
الخلاصة الأساسية
LGFPP warpage is mainly caused by anisotropic shrinkage due to fiber orientation
