PETG '2079851475616104452 machine clamping force calculation insufficient
Problembeschreibung
During mold closing, the mold is pushed open creating a gap and material overflows, producing product flash.
Ursachenanalyse
The clamping force calculation did not fully consider PETG flowability, and the clamping force is insufficient to resist cavity pressure.
Lösung
Recheck the clamping force requirement (cavity projected area * cavity pressure); increase the clamping force.
Wichtigste Erkenntnis
PETG insufficient clamping force directly causes flash.
