PBT holding pressure management
문제 현상
Sink marks and unstable dimensions.
원인 분석
Improper holding pressure setting; the holding pressure window is important for crystalline materials.; when troubleshooting on site, 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 when troubleshooting
해결 방법
①Optimize holding pressure and time; ②set according to solidification time; ③segmented holding pressure; ④verify the effect.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Holding pressure is the core of PBT dimensional management.; 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 similar problems in the future
