PPSU holding pressure management
문제 현상
PPSU holding pressure pressure and time; sink mark and stress balance.
원인 분석
PPSU holding pressure compensates shrinkage; time according to wall thickness; stress influence; gate freezing; weight optimization.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
해결 방법
①Holding pressure optimization; ②time according to wall thickness; ③stress balance; ④weight monitoring; ⑤standardization execution.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
PPSU holding pressure is a balance of quality and stress; optimization is based on testing; standardization ensures consistency.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
