CMC Screw Slippage
Problembeschreibung
During CMC extrusion, the screw slips, feeding does not advance, and output drops sharply
Ursachenanalyse
CMC particles melt too early in the feeding section, forming a lubricating film that causes screw slippage; feeding section temperature is too high
Lösung
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
Wichtigste Erkenntnis
Screw slippage is caused by premature melting; cooling the feeding section is the key
