PETG '2079851475616104452 hot runner leakage
Problembeschreibung
The PETG hot runner system leaks melt at high temperature, and material overflows.
Ursachenanalyse
Hot runner sealing surfaces fit poorly, thermal expansion increases the gap, system pressure high, seals aged.
Lösung
Repair the sealing surface fit accuracy; consider thermal expansion and reserve pre-tightening force; reduce system pressure; use high-temperature resistant sealing materials.
Wichtigste Erkenntnis
PETG hot runner leakage needs prevention from mechanical precision and thermal management.
