PA66 thermocouple calibration
Sorun Belirtisi
Multiple machines produce the same PA66 product, process parameters identical but quality performance differs
Neden Analizi
Thermocouple aging degrees differ among machines, displayed temperature the same while actual melt temperature differs, process parameters lose comparability; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Establish regular thermocouple calibration system, compare with a standard thermometer; replace when deviation exceeds ±5℃; check temperature controller synchronously during mold change; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Temperature measurement consistency is the premise of multi-machine process replication; after confirming effectiveness, fix 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
