Severe flash in EAA '2079851475616104452
Sorun Belirtisi
The parting line flash of EAA injection molded products is 0.05-0.1mm, width >2mm, requiring secondary trimming
Neden Analizi
Injection pressure too high >80MPa, melt overflows from the parting line; insufficient clamping force; mold parting line fitting gap >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 mold penetration tendency
Temel Çıkarım
Flash is caused by high-pressure injection and mold gaps; reducing pressure and improving mold fitting are the key
