Equipment configuration and main parameters
Expansion Control System (ECS)
Main improvements in this test
Improve the structure of the conditioner to increase the conditioning time and the uniformity of the conditioning.
Adjust the operating parameters of the conditioner to increase the conditioning time.
Adjust the operating parameters of the extruder.
Adjust the aspect ratio of the template.
Conditioner system
Adjust the paddles of the upper single-axis conditioner to increase the filling degree
The paddles of the discharge port (3 groups of 12 pieces) are changed from the original forward push to the reverse push of 45 degrees
The number of water adding nozzles is increased to 4 , improve the uniformity of water addition
The number of water addition nozzles is increased to 4, improving the uniformity of water addition
Before improvement: poor conditioning uniformity
After improvement: improved conditioning uniformity
Double-axis conditioner: through the adjustment of frequency conversion, increase the filling degree of materials and improve the conditioning time
The total conditioning time is increased by about 30s
Fill% of single conditioner is 25%
Fill% of DDC is 55%
The total conditioning time is increased from the original 120s to about 180s
The screw configuration has not changed
Mold: aspect ratio changed from 3 to 2.5

Suggestions for next improvement
This test mainly improves the conditioning time and conditioning uniformity, and the stability in water has been improved to a certain extent.
If you need to further improve the stability in water, it is recommended to replace the conditioner with a larger volume.
