POM Short Shot
문제 현상
Short shot at the filling end of POM thin-walled parts
원인 분석
POM freezes quickly; during end filling the melt front has already cooled, and poor venting aggravates short shot; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Open vent grooves at the end; increase injection speed; take the upper limit for melt and mold temperature; 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
Short shots of fast-freezing materials require coordination of speed, temperature, and venting; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
