Die Casting

Many of the engineering properties of steel can be realized with Ductile Iron Casting. It has the ability to be cast in heavier sections and can be used to produce larger castings than malleable iron. Ductile Iron Casting has replaced forgings, weldments and steel castings in an ever increasing number of applications.

Ductile Iron Casting is particularly well suited for:

  • Valves
  • Pump - Gears and Rollers
  • Spring Hangers
  • Suspension Parts
  • Wheel Hubs
  • Bearing Caps
  • Hardware
  • Universal Joints
  • Threadless Connectors and Flanges
  • Various Automotive and Agricultural Items.

Molten metal is injected, under pressure, into hardened steel dies, often water cooled. Dies are opened, and castings are ejected.
