DSTDP insufficient flatness
ظاهرة المشكلة
DSTDP flat plate product flatness >0.5mm/100mm, warpage
تحليل الأسباب
DSTDP shrinkage rate large and different in each direction; mold cooling uneven; residual stress release causing continuous warpage
الحل
1) Uniform mold temperature to reduce temperature difference; 2) increase holding pressure to reduce shrinkage difference; 3) annealing to release residual stress
الخلاصة الأساسية
Insufficient flatness is caused by shrinkage difference and stress; uniform cooling and annealing are key
