PMMA Board Storage Temperature
문제 현상
PMMA boards warped and deformed after being stored in the warehouse in summer
원인 분석
The board creeps under the long-term action of temperature and its own weight; improper vertical placement or excessively high temperature accelerates deformation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Lay the boards flat or store them nearly vertically; control warehouse temperature; conduct regular inspections during long-term storage; 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
Board storage posture and temperature determine deformation risk; 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
