POM drying equipment selection
Problem Phenomenon
POM consumption is small; is it necessary to equip a dehumidifying dryer
Cause Analysis
POM's drying requirements are not high, but drying opened material still requires reliable means; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
For small consumption, an insulated oven at 80-100°C can be used for drying; for large consumption, a dehumidifying dryer is more stable; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
POM drying equipment is matched to consumption, and the accuracy requirement is not high; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
