TPU Drying Records
Fenómeno do problema
When tracing a bubble problem, there is no drying data
Análise das causas
No records of drying operations; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solução
Establish drying records: temperature, time, dew point, moisture content; associate with batch number; 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
Conclusão principal
Drying records are the foundation of TPU traceability; 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 similar problems in the future
