PVC Drying Records
문제 현상
No drying data available when tracing the bubble problem
원인 분석
Drying operations were not recorded, so the state of the problem batch cannot be restored; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Establish drying records: temperature, time, batch association; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
핵심 요약
Drying records are the basis of traceability; 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 in the future
