CMC Screw Slippage
문제 현상
During CMC extrusion, the screw slips, feeding does not advance, and output drops sharply
원인 분석
CMC particles melt too early in the feeding section, forming a lubricating film that causes screw slippage; feeding section temperature is too high
해결 방법
1)Lower feeding section temperature by 10-15°C to delay melting; 2)Deepen feeding section flights to increase material grip; 3)Dry particle surface to reduce lubrication
핵심 요약
Screw slippage is caused by premature melting; cooling the feeding section is the key
