Unbalanced multi-cavity filling in EVA '2079851475616104452
Sorun Belirtisi
In EVA '2079851475616104452 8-cavity mold, filling amount differs ±15% between cavities with some cavities short shot and some flash
Neden Analizi
Unbalanced runner design with inconsistent runner length and resistance for each cavity; inconsistent gate size for each cavity
Çözüm
1) Adopt balanced runner design to ensure equal length and equal resistance for each cavity; 2) Gate size of each cavity precisely consistent within ±0.01mm; 3) Reduce injection speed to reduce resistance difference influence; 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 key
