CMC Screw Slippage
Fenómeno do problema
During CMC extrusion, the screw slips, feeding does not advance, and output drops sharply
Análise das causas
CMC particles melt too early in the feeding section, forming a lubricating film that causes screw slippage; feeding section temperature is too high
Solução
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
Conclusão principal
Screw slippage is caused by premature melting; cooling the feeding section is the key
