Product severe warpage deformation
문제 현상
The product bends, twists or dishes, and cannot be solved after multiple process adjustments
원인 분석
Fiber orientation causes anisotropic shrinkage (small longitudinally, large transversely); uneven mold cooling causes temperature gradient stress; asymmetric geometric structure constraints of the product
해결 방법
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
핵심 요약
LGFPP warpage is mainly caused by anisotropic shrinkage due to fiber orientation
