POM water channel design
문제 현상
Uneven cooling of the POM mold causes warpage
원인 분석
The water channel layout is unreasonable, and cooling is inconsistent at various points of the cavity; 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 data and should be confirmed first during troubleshooting
해결 방법
Design water channels with equal length in parallel; control the temperature difference within 5°C; descale regularly; after adjustment, take continuous samples 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
Water channel balance is the design prerequisite for warpage prevention; after confirming effectiveness, fix 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
