Unbalanced multi-cavity filling in PVA '2079851475616104452
Sorun Belirtisi
PVA injection 8-cavity mold, filling amount of each cavity differs by ±15%, some cavities short shot and some flash
Neden Analizi
Unbalanced runner design, runner length and resistance of each cavity inconsistent; gate size of each cavity inconsistent
Çözüm
1) Adopt balanced runner design to ensure equal length and resistance of each cavity runner; 2) Gate size 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 runner and mold flow analysis are the key
