Information : Austempered Ductile Iron Minifactory
Rock Island Arsenal (RIA) has developed a unique, versatile Austempered Ductile Iron Minifactory with in-house expertise and production and test capabilities. The minifactory arose from a congressionally-mandated program to explore uses for American ductile iron and austempered ductile iron in defense-related applications.
Austempered Ductile Iron (ADI) is basically the same composition as ductile iron, but is heat treated to give it higher strength. Some of the advantages of ADI include competitive strength-to-weight ratios, suitability for thinner walled and complex castings, low machining costs, and better machinability. RIA's minifactory has the capability to import or develop 3D CAD/CAM part models, design and make the 3D casting model, verify the casting model using casting fill and solidification simulation, make rapid prototype or conventional patterns, mold and cast, heat treat, machine, test, evaluate, and report as required. In-house forging, plating, and welding services are also available to support the minifactory.
