Insufficient filling of PLA '2079851475616104452 (short shot)
문제 현상
The cavity is not completely filled during PLA '2079851475616104452.
원인 분석
The PLA melt viscosity is relatively large and the fluidity is not as good as PP, etc.; the injection pressure and speed are insufficient; the melt temperature is low; the gate is too small.
해결 방법
Raise the melt temperature to 180-200°C; increase the injection pressure and speed; enlarge the gate; the mold temperature can be appropriately lowered.
핵심 요약
PLA fluidity is the main cause of short shots.
