Poor plasticization due to low back pressure in PLA '2079851475616104452
Problem Phenomenon
When the back pressure is insufficient, PLA plasticization is incomplete.
Cause Analysis
The viscosity of PLA is high, and a certain back pressure is required to ensure plasticization and mixing.
Solution
Set the back pressure at 0.5-1.5MPa; observe the melt temperature and plasticization quality.
Key Takeaway
The PLA back pressure needs to match the melt characteristics.
