Poor plasticization due to low back pressure in PLA '2079851475616104452
ظاهرة المشكلة
When the back pressure is insufficient, PLA plasticization is incomplete.
تحليل الأسباب
The viscosity of PLA is high, and a certain back pressure is required to ensure plasticization and mixing.
الحل
Set the back pressure at 0.5-1.5MPa; observe the melt temperature and plasticization quality.
الخلاصة الأساسية
The PLA back pressure needs to match the melt characteristics.
