Insufficient filling of PAR '2079851475616104452 (short shot)
ظاهرة المشكلة
The cavity is not completely filled and the product is short of material.
تحليل الأسباب
The PAR melt viscosity is high, and the flowability is still limited at a processing temperature of around 300°C; the injection pressure and speed are insufficient.
الحل
Raise the melt temperature to 300-320°C; increase the injection pressure and speed; enlarge the gate and runner.
الخلاصة الأساسية
The high viscosity of PAR is the main cause of short shot.
