PC Silver Streak Multi-Cause Troubleshooting
문제 현상
[Problem Phenomenon] PC product silver streaks recur, and single machine adjustment cannot cure them
원인 분석
The main cause of PC silver streaks is moisture, but degradation from excessive melt temperature, shear overheating and material contamination also cause silver streaks; classify and locate by distribution position: random all-over distribution indicates moisture, fixed at the gate indicates shear
해결 방법
First verify the moisture content ≤0.02%; then check the melt temperature and shear; for gate-fixed silver streaks, reduce the speed and enlarge the gate; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
핵심 요약
PC silver streaks divide into three routes of moisture, heat and shear, and the distribution position points to the cause; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
