PETG '2079851475616104452 improper back pressure setting, poor plasticization
ظاهرة المشكلة
Plasticization is uneven, with unmelted particles in the melt or insufficient mixing.
تحليل الأسباب
Back pressure too low, mixing and plasticization insufficient; back pressure too high increases shear heat and degradation risk.
الحل
Optimize back pressure setting to 0.5-1.5MPa; adjust according to plasticization quality and regrind condition.
الخلاصة الأساسية
PETG back pressure setting needs to balance plasticization quality and degradation risk.
