PESU Screw Compression Ratio
Problem Phenomenon
Improper PESU screw compression ratio; plasticizing quality and shear heat problems.
Cause Analysis
PESU screw compression ratio of 2.0:1 is recommended; too high causes shear heat; too low causes insufficient plasticizing; wear influence; long-term stability.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Configure screw compression ratio at 2.0:1; ②plasticizing quality monitoring; ③wear check; ④actual temperature measurement.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
The 2.0:1 of PESU screws is a clear standard; configuration and maintenance are equally important; monitoring ensures plasticizing quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
