PAEK insufficient mold filling flow
문제 현상
Thin-wall cavity underfilled
원인 분석
Processing temperature <350°C, near the melting point the melt viscosity is extremely high; mold temperature low and the melt solidifies quickly
해결 방법
Increase the melt temperature to 370-390°C; keep the mold temperature at 180-200°C
핵심 요약
PAEK requires a processing temperature sufficiently above Tm to ensure flowability
