HDPE Dimensional Drift
문제 현상
HDPE product dimensions continue to change after storage
원인 분석
Post-crystallization and stress relaxation cause dimensions to change slowly; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Inspect products after aging; ensure sufficient crystallization by process; note the state on drawings; after adjustment, continuously sample 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
HDPE dimensions are based on inspection after aging; 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
