Poor plasticization due to low back pressure in PLA '2079851475616104452
Problembeschreibung
When the back pressure is insufficient, PLA plasticization is incomplete.
Ursachenanalyse
The viscosity of PLA is high, and a certain back pressure is required to ensure plasticization and mixing.
Lösung
Set the back pressure at 0.5-1.5MPa; observe the melt temperature and plasticization quality.
Wichtigste Erkenntnis
The PLA back pressure needs to match the melt characteristics.
