Stainless Steel Casting Equipment & Technology
TFG USA uses modern foundry equipment and process controls to maintain consistent casting quality and material properties.
- Induction Melting: Controlled melting systems support stainless steel alloy production and temperature control.
- Solidification Modeling: Casting simulation helps evaluate metal flow, solidification, gating, and potential defect areas.
- Metallurgical Analysis: Material analysis supports chemical composition and casting quality verification.
- Sand Testing: Controlled testing of molding materials helps maintain consistent mold and casting conditions.
Secondary Processes & Finishing
TFG USA can provide secondary operations to bring stainless steel castings to final dimensions, surface requirements, and functional specifications.
- CNC Machining: Milling, turning, drilling, tapping, and other operations for final dimensions and critical features.
- Heat Treatment: Controlled thermal processing to achieve specified mechanical properties.
- Grinding & Deburring: Removes excess material and improves surface condition.
- Passivation: Improves the corrosion resistance of stainless steel surfaces.
- Polishing: Provides improved surface finish for functional or appearance requirements.
- Inspection: Dimensional inspection and material documentation to verify customer specifications.
