PMMA Material Changeover Cleaning
문제 현상
After PMMA material changeover, black specks and color mixing persist for a long time
원인 분석
PMMA melt has high viscosity, making residual material in dead spots difficult to clean; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
해결 방법
Thoroughly replace with purging compound during changeover; regularly disassemble and clean dead spots; schedule production from light to dark colors; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
핵심 요약
Material changeover of high-viscosity materials requires purging compound plus disassembly and cleaning; 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
