TPE Product Color Difference
Problem Phenomenon
Product color does not match the standard sample.
Cause Analysis
Poor color masterbatch compatibility or inaccurate metering; processing temperature affects color development.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Select compatible color masterbatch; ②stabilize metering; ③control the processing temperature; ④color difference test by batch.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Color difference management relies on color masterbatch and temperature control; batch testing before release.; 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
