MP screw slipping
문제 현상
during MP extrusion the screw slips, feed does not advance, output drops sharply
원인 분석
MP pellets melt too early in the feed section, forming a lubricating film causing screw slip; feed section temperature too high
해결 방법
1) lower feed section temperature 10-15°C to delay melting; 2) deepen the feed section flight to increase material grip; 3) dry the pellet surface to reduce lubrication
핵심 요약
screw slipping is caused by premature melting; lowering feed section temperature is key
