Improper multi-stage speed settings produce jetting, weld lines or surface defects
ظاهرة المشكلة
Improper multi-stage speed settings produce jetting, weld lines or surface defects
تحليل الأسباب
Slow stage too long, filling time too long, surface condensation
Fast stage too fast producing jetting or excessive shear
Improper speed switchover point selection, unsmooth transition
Too many or too few stages set, control complex or not fine enough
Unreasonable speed proportion allocation of each stage
الحل
Initial slow speed to prevent jetting (5-15% of maximum speed)
Middle fast filling (60-80% of maximum speed)
Final stage deceleration to prevent flash (20-40% of maximum speed)
Reasonably set 3-5 speed stages
Adjust each stage proportion according to the cavity structure
الخلاصة الأساسية
Multi-stage speed needs optimization according to the cavity structure
