EMA '2079851475616104452 Severe Flash
Sorun Belirtisi
EMA injection molded products have flash of 0.05-0.1mm and width >2mm at the parting line, requiring secondary trimming
Neden Analizi
Injection pressure too high >80MPa, melt overflows from the parting line; insufficient clamping force; mold parting surface fitting gap >0.02mm
Çözüm
1) Reduce injection pressure to 60-70MPa; 2) Increase clamping force or use a larger-tonnage '2079851475616104452 machine; 3) Mold fitting gap <0.02mm; 4) Increase melt viscosity to reduce mold penetration tendency
Temel Çıkarım
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fitting are key
