Glass Fibre extruder large current fluctuation
Problembeschreibung
During Glass Fibre extrusion, main machine current fluctuates ±15-20%, affecting extrusion stability and product quality
Ursachenanalyse
Feed amount unstable; Glass Fibre melt viscosity sensitive to temperature, temperature fluctuation causes large viscosity change; screw structure unsuitable causes uneven melting
Lösung
1) Loss-in-weight feeder for stable feeding; 2) precision temperature control ±1°C; 3) select dedicated screw; 4) increase screw mixing section to ensure uniform melting
Wichtigste Erkenntnis
Current fluctuation is caused by unstable feeding, poor temperature control and unsuitable screw; system optimization is key
