MP '2079851475616104452 severe flash
Sorun Belirtisi
MP injection molded products have flash at the parting line 0.05-0.1mm, width >2mm, requiring secondary trimming
Neden Analizi
injection pressure too high >80MPa, melt overflows from the parting line; clamping force insufficient; mold parting line mating gap >0.02mm
Çözüm
1) reduce injection pressure to 60-70MPa; 2) increase clamping force or use a larger tonnage injection machine; 3) mold mating 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 mating are key
