MP insufficient flatness
문제 현상
MP flat products flatness >0.5mm/100mm, warpage
원인 분석
MP shrinkage large and anisotropic; mold cooling uneven; residual stress release causing continuous warpage
해결 방법
1) uniform mold temperature to reduce temperature difference; 2) increase holding pressure to reduce shrinkage difference; 3) annealing to release residual stress
핵심 요약
insufficient flatness is caused by shrinkage difference and stress; uniform cooling and annealing are key
