TPE Thermocouple Calibration
Fenómeno do problema
Multiple machines with the same parameters have different quality
Análise das causas
Thermocouple deviation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry information and should be confirmed first during troubleshooting
Solução
Regular thermocouple calibration; replace if the deviation exceeds ±3℃; 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
Temperature measurement is unified; after confirming effectiveness, solidify 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
