Premature Gate Freezing in CMC '2079851475616104452
문제 현상
In CMC injection molded products, the gate freezes within 0.5-1s in the holding stage, holding pressure cannot be transmitted, and product shrinkage is severe
원인 분석
Gate size is too small, diameter <1mm, causing rapid freezing; injection temperature is low; mold temperature is low, accelerating gate cooling
해결 방법
1)Increase gate diameter to 1.5-2mm; 2)Increase injection temperature to 20-25°C; 3)Increase mold temperature to 40-50°C to delay gate freezing; 4)Holding pressure decays in steps rather than being suddenly released
핵심 요약
Premature gate freezing is caused by small gate and low temperature; enlarging the gate and increasing temperature are fundamental measures
