Injection Molding
2 views
Abnormal injection melt viscosity
Problem Phenomenon
The melt flows with difficulty, the injection pressure is high, and the filling is incomplete
Cause Analysis
Temperature <210C causes insufficient plasticization, or >270C causes crosslinking
Solution
Strict 220-260C segmented temperature control, empty the material after a 10min shutdown
Key Takeaway
The processing temperature window is narrow and the operation requirements are high
