Abnormal injection melt viscosity

Problembeschreibung

The melt flows with difficulty, the injection pressure is high, and the filling is incomplete

Ursachenanalyse

Temperature <210C causes insufficient plasticization, or >270C causes crosslinking

Lösung

Strict 220-260C segmented temperature control, empty the material after a 10min shutdown

Wichtigste Erkenntnis

The processing temperature window is narrow and the operation requirements are high
