EEA Screw Slipping
Fenómeno do problema
During EEA extrusion, the screw slips, feed does not advance, output drops sharply
Análise das causas
EEA pellets melt too early in the feeding section, forming a lubricating film causing screw slip; feeding section temperature too high
Solução
1) Lower the feeding section temperature by 10-15°C to delay melting; 2) Deepen the feeding section flight to increase material grip; 3) Dry the pellet surface to reduce lubrication
Conclusão principal
Screw slipping is caused by premature melting; cooling the feeding section is key
