PA6 Drying Curve Record
문제 현상
The same dryer gives inconsistent drying effects across different shifts, and quality problems cannot be traced
원인 분석
Lacking drying process records, the actual drying temperature, time, and loading volume differ across shifts, and when quality problems occur, the specific state of the drying step cannot be traced back
해결 방법
Establish a drying record sheet, recording drying temperature, time, loading volume, dew point, and moisture content sampling results for each batch; the records are associated with product batches to facilitate quality traceability
핵심 요약
Data-based recording of the drying process is the foundation of quality traceability, and operation from memory cannot guarantee consistency; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
