MP '2079851475616104452 premature gate freeze
Sorun Belirtisi
MP injection molded product gate freezes within 0.5-1s in the holding stage, holding pressure cannot be transmitted, product shrinkage severe
Neden Analizi
gate size too small, diameter <1mm, causing fast freezing; injection temperature low; mold temperature low, accelerating gate cooling
Çözüm
1) increase gate diameter to 1.5-2mm; 2) raise injection temperature to 150-170°C; 3) raise mold temperature to 40-50°C to delay gate freezing; 4) stepwise decay of holding pressure rather than sudden release
Temel Çıkarım
premature gate freezing is caused by small gate and low temperature; enlarging the gate and raising temperature are fundamental measures
