PETG '2079851475616104452 in-mold pressure too high
ظاهرة المشكلة
During PETG '2079851475616104452, the cavity pressure is too high, causing flash, mold deformation or equipment alarm.
تحليل الأسباب
Injection pressure too high, melt viscosity too low (processing temperature too high), insufficient venting back pressure, wall thickness too thin and filling resistance large.
الحل
Appropriately reduce injection pressure and speed; lower the barrel temperature to 230-250°C; improve venting; increase wall thickness or enlarge the gate.
الخلاصة الأساسية
PETG in-mold pressure abnormality requires comprehensive adjustment of pressure, temperature and venting.
