EMA screw slippage
Sorun Belirtisi
Screw slippage during EMA extrusion with feed not advancing and output dropping sharply
Neden Analizi
EMA pellets melt too early in the feed section forming a lubricating film causing screw slippage; feed section temperature too high
Çözüm
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
Temel Çıkarım
Screw slippage is caused by premature melting; lowering feed section temperature is key
