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

The Production Process 

The "as-cast" wheel is produced in a six step process.

1. The molten iron is poured into the mold and allowed to cool.

2. After cooling, the casting is removed from the sand mold by "shaking out" the sand.

3.  The runners and gating are cut off the casting.

4. The casting is shot-basted to remove residual sand on the surface.

5.  Flash lines and gating/riser stubs are ground off.

6.  The casting is abrasive shot-blasted for a finished appearance.
