원인 분석
The melt viscosity of PC is high and sensitive to temperature; the injection pressure is insufficient; the gate and runner resistance is large; the mold temperature is low.
해결 방법
Increase the melt temperature to 290-310°C; increase the injection pressure; enlarge the gate and runner; mold temperature 90-120°C.
핵심 요약
The high viscosity of PC is the main cause of short shot due to poor fluidity.
