SMMA Screw Speed
문제 현상
Improper SMMA screw speed, shear heat or insufficient plasticization, medium speed recommended.
원인 분석
SMMA screw speed recommended medium; too fast causes shear heat; too slow causes insufficient plasticization; coordinate with back pressure; melt quality.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
해결 방법
①Control screw speed at medium; ②coordinate with back pressure; ③melt quality monitoring; ④verify plasticization uniformity.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
SMMA screw medium speed is a balanced choice; coordinated management prevents extremes; verification keeps melt quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
