EEA injection gate freezing too early
Sorun Belirtisi
EEA injection molded product gate freezes within 0.5-1s during the holding stage, holding pressure cannot be transmitted, severe product shrinkage
Neden Analizi
Gate size too small, diameter <1mm, causing rapid freezing; injection temperature too low; mold temperature too low accelerating gate cooling
Çözüm
1) Increase gate diameter to 1.5-2mm; 2) Increase injection temperature to 160-210°C; 3) Increase mold temperature to 40-50°C to delay gate freezing; 4) Holding pressure step decay instead of sudden release
Temel Çıkarım
Premature gate freezing is caused by small gate and low temperature; enlarging the gate and increasing temperature are the fundamental measures
