Cause Analysis
PA12 drying requirements are relatively mild but still need to meet standards; dew point monitoring is important.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solution
①Dehumidifying dryer; ②dew point monitoring; ③regular calibration; ④moisture content detection.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Drying equipment is the first gate of quality.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a troubleshooting reference for subsequent similar problems
