EVOH injection flash is severe
문제 현상
EVOH injection molded product parting line flash 0.05-0.1mm, width >2mm, requiring secondary trimming
원인 분석
Injection pressure too high >80MPa with melt overflowing from the parting line; insufficient clamping force; mold parting line fit gap >0.02mm
해결 방법
1) Reduce injection pressure to 60-70MPa; 2) Increase clamping force or use a larger tonnage '2079851475616104452 machine; 3) Mold fit gap <0.02mm; 4) Increase melt viscosity to reduce mold penetration tendency
핵심 요약
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fit are key
