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.
Metals:
Aluminum, Zinc, Magnesium, and limited Brass. Stainless steel.
Size Range:
Not normally over 2 feet square. Some foundries capable of larger sizes.
Tolerances:
Al and Mg ± . 002"/in.
Zinc ± . 0015"/in.
Brass ± . 005"/in.
Add ± . 001" to ± . 015" across parting line depending on size.
Surface Finish:
32-63RMS
Minimum Draft Requirements:
Al & Mg: 1° To 3°
Zinc: 1/2° To 2°
Brass: 2° To 5°
Normal Minimum Section Thickness:
Al: . 03" Small Parts: . 06" Medium Parts
Mg: . 03" Small Parts: . 045" Medium Parts
Zinc: . 025" Small Parts: . 040" Medium Parts
Ordering Quantities:
Usually 2, 500 and up.
Normal Lead Time:
Samples: 12-20 weeks.
Production:
4-8 weeks A. S. A.
