ظاهرة المشكلة
The cavity is not completely filled during PLA '2079851475616104452.
تحليل الأسباب
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.
الحل
Raise the melt temperature to 180-200°C; increase the injection pressure and speed; enlarge the gate; the mold temperature can be appropriately lowered.
الخلاصة الأساسية
PLA fluidity is the main cause of short shots.
