POM product melt temperature actual measurement deviation
Problem Phenomenon
Set at 210℃, actual measurement is higher.
Cause Analysis
Shear heat (high screw speed and back pressure); POM has zero tolerance for overheating.
Solution
①Reduce screw speed and back pressure; ②calibrate with actual melt temperature measurement; ③screw evaluation.
Key Takeaway
POM melt temperature must be actually measured.
