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