A Design Study in Austempered Ductile Iron - Smith Foundry Drive Wheel

Quality Assurance

The Smith Foundry applies ISO-9000 quality management principles at each stage of the casting process to assure quality.

  • Precise testing and control of the alloy composition through emission spectrographic analysis of the furnace and ladle chemistry. 

Emission Spectrometer
  • Mechanical testing of heat-treated castings.

    • Tensile strength and Charpy pendulum impact testing of witness bars.

    • Brinell hardness testing on selected areas of the casting.

  • Dimensional checks on all critical features.

  • Soundness checks by radiography and sectioning on prototype castings.
