Insufficient mold filling flow length

문제 현상

Thin-wall or complex parts of PES products are incompletely filled

원인 분석

Barrel temperature too low <310°C causing high melt viscosity; mold temperature <120°C causes the melt front to cool rapidly

해결 방법

Increase the melt temperature to 340-370°C to reduce melt viscosity; increase the mold temperature to 140-160°C to extend the melt flow window

핵심 요약

PES requires higher processing temperature and mold temperature to assist filling
