Large current fluctuation of EEA extruder
Fenómeno do problema
During EEA extrusion the main motor current fluctuates ±15-20% affecting extrusion stability and product quality
Análise das causas
Unstable feeding amount; EEA melt viscosity sensitive to temperature, temperature fluctuation causing large viscosity change; unsuitable screw structure causing uneven melting
Solução
1) Gravimetric feeder for stable feeding; 2) Precision temperature control ±1°C; 3) Select a special screw; 4) Increase the screw mixing section to ensure uniform melting
Conclusão principal
Current fluctuation is caused by unstable feeding, poor temperature control and unsuitable screw; system optimization is the key
