EMA screw slippage
Fenómeno do problema
Screw slippage during EMA extrusion with feed not advancing and output dropping sharply
Análise das causas
EMA pellets melt too early in the feed section forming a lubricating film causing screw slippage; feed section temperature too high
Solução
1) Lower feed section temperature by 10-15°C to delay melting; 2) Deepen feed section flights to increase gripping force; 3) Dry pellet surface to reduce lubrication
Conclusão principal
Screw slippage is caused by premature melting; lowering feed section temperature is key
