PMMA Short Shot

문제 현상

Thin-wall long-flow material shortage.

원인 분석

PMMA melt viscosity is high and flow is slow; insufficient pressure and speed, low mold temperature.

해결 방법

①Increase the injection pressure (60~120MPa); ②Raise melt temperature and mold temperature; ③Large gate; ④Optimize the runner.

핵심 요약

PMMA short shot = the pressure account of high viscosity.

PMMA; short shot; viscosity; injection pressure; mold temperature
