Supersand: Redefining Efficiency in Foundry Facing Sands
In metal casting, facing sand serves as the critical interface between molten metal and mold surfaces. Supersand elevates this component through engineered mineral blends, achieving 40% higher thermal stability than industry averages. Foundries leveraging this material report 18% fewer casting defects and a 22% reduction in sand replacement cycles, directly lowering operational downtime.
Engineering Superiority in Thermal Management
Traditional silica-based sands begin degrading at 1450°C, while Supersand maintains structural integrity up to 1680°C. This 15.8% temperature threshold increase enables longer pour times for complex geometries. Its low-clay formulation (2.8% binder content vs. typical 6-8%) minimizes gas evolution during casting, reducing porosity issues by 31% across aluminum and iron applications.
| Parameter | Supersand | Competitor A | Competitor B |
|---|---|---|---|
| Compressive Strength (MPa) | 4.2 | 3.1 | 2.8 |
| Permeability Number | 142 | 98 | 87 |
| Reclamation Rate (%) | 92 | 74 | 68 |
