PETG '2079851475616104452 machine clamping force calculation insufficient
ظاهرة المشكلة
During mold closing, the mold is pushed open creating a gap and material overflows, producing product flash.
تحليل الأسباب
The clamping force calculation did not fully consider PETG flowability, and the clamping force is insufficient to resist cavity pressure.
الحل
Recheck the clamping force requirement (cavity projected area * cavity pressure); increase the clamping force.
الخلاصة الأساسية
PETG insufficient clamping force directly causes flash.
