Extrusion output below design capacity
Problem Phenomenon
Extrusion output below design capacity, production efficiency not up to standard
Cause Analysis
Screw design not suitable for cellulose acetate butyrate
Improper extrusion temperature setting, low plasticization efficiency
Screen pack resistance too large
Screw speed low
Raw material fluidity insufficient
Solution
Select a screw design suitable for cellulose acetate butyrate
Reasonably set extrusion temperature at 170-230°C
Appropriately reduce the number of screen pack layers
Appropriately increase screw speed
Check raw material quality and fluidity
Key Takeaway
Extrusion output requires optimizing screw and temperature
