EAA screw slipping
Sorun Belirtisi
Screw slipping during EAA extrusion, feed not advancing, output dropping sharply
Neden Analizi
EAA granules melting too early in the feeding section forming a lubricating film causing screw slipping; feeding section temperature too high
Çözüm
1) Reduce feeding section temperature by 10-15°C to delay melting; 2) Deepen feeding section flights to increase material gripping force; 3) Dry granule surfaces to reduce lubrication
Temel Çıkarım
Screw slipping is caused by premature melting; lowering the feeding section temperature is key
