Problembeschreibung

Large melt pressure decay in the runner causes insufficient cavity pressure.

Ursachenanalyse

Runner too long or too thin with large resistance, small gate size, melt temperature too low with high viscosity.

Lösung

Shorten the runner and increase cross-section; enlarge the gate; increase melt temperature.

Wichtigste Erkenntnis

PCTG pressure loss is related to runner and gate design.
