TPU product batch color difference
문제 현상
Inconsistent color between batches.
원인 분석
Masterbatch metering fluctuations or base material batch color difference; processing temperature differences also affect color development; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①stabilize masterbatch metering; ②control base material batches; ③stabilize processing temperature; ④color difference testing by batch; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Batch color difference relies on stable metering and temperature control; testing and release are the guarantee; 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
