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.
