CEF internal unmelted particles
Problem Phenomenon
Unmelted transparent or translucent particles appear inside the CEF product
Cause Analysis
The screw plasticizing capacity is insufficient and the temperature is low; the feeding amount is too large and exceeds the plasticizing capacity; the CEF melting temperature is high
Solution
1) Increase the processing temperature to ensure full melting; 2) Reduce the feeding amount to match the plasticizing capacity; 3) Increase the screw mixing section
Key Takeaway
Unmelted particles are caused by insufficient plasticization; increasing the temperature and reducing the feeding are the key
