Unbalanced Multi-Cavity Filling in CMC '2079851475616104452
Sorun Belirtisi
In CMC '2079851475616104452 with an 8-cavity mold, the filling amount of each cavity differs by ±15%, with short shots in some cavities and flash in others
Neden Analizi
Runner design is unbalanced and the runner lengths and resistances of each cavity are inconsistent; gate sizes of each cavity are inconsistent
Çözüm
1)Adopt balanced runner design to ensure equal length and equal resistance of each cavity runner; 2)Gate sizes of each cavity precisely consistent ±0.01mm; 3)Reduce injection speed to reduce the influence of resistance differences; 4)Use mold flow analysis software to optimize runner design
Temel Çıkarım
Unbalanced multi-cavity filling is caused by runner design; balanced runners and mold flow analysis are the key
