PC/ABS color matching color difference
Fenómeno do problema
Color deviates from the standard sample.
Análise das causas
Color masterbatch compatibility or metering problem; temperature affects color development.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
①Select compatible color masterbatch; ②stabilize metering; ③control temperature; ④test by batch.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record the parameter changes, to facilitate locating the effective measures
Conclusão principal
Color difference relies on color masterbatch and temperature control management.; 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 similar problems later
