DSTDP severe internal stress concentration
ظاهرة المشكلة
DSTDP product internal stress >15MPa, causing cracking during storage
تحليل الأسباب
Injection speed too fast, orientation stress large; uneven cooling freezes thermal stress; improper gate position, flow orientation concentrated
الحل
1) Reduce injection speed to reduce orientation; 2) uniform mold temperature to reduce thermal stress; 3) anneal 80°C/4h to release stress; 4) optimize gate position
الخلاصة الأساسية
Internal stress is caused by fast injection and uneven cooling; reducing speed, uniform cooling and annealing are key
