Discharge Method Comparison
| Feature | Screw Extrusion Discharge (This Model) | Tilting Discharge |
|---|---|---|
| Efficiency | Continuous and controlled output, especially for sticky or viscous materials | Batch discharge, may leave residues |
| Material Flow | Smooth extrusion through screw barrel | Relies on gravity, less control |
| Space Requirement | Compact design, no need for tilting clearance | Requires larger working area for tank rotation |
| Operator Effort | Easier operation, minimal manual handling | Requires more manual operation |
| Best for | High-viscosity materials like silicone rubber, adhesives | Medium-viscosity materials, easier to flow |
