CEF flatness insufficient
ظاهرة المشكلة
The flatness of the CEF flat plate product is >0.5mm/100mm, warpage
تحليل الأسباب
The CEF shrinkage rate is large and anisotropic; the mold cooling is uneven; the release of residual stress causes continuous warpage
الحل
1) Uniform mold temperature to reduce temperature difference; 2) Increase the holding pressure to reduce shrinkage differences; 3) Annealing to release residual stress
الخلاصة الأساسية
Insufficient flatness is caused by shrinkage differences and stress; uniform cooling and annealing are the key
