This complex electronics sensor housing was designed as an investment casting due to its complexity and lower manufacturing cost compared to an alternative fabricated assembly of numerous machined components.
Manufactured by Uni-Cast, Inc. of Londonderry, NH, the 24″ x 22″ x l6″ aluminum casting is one of two winners in the military category of the Investment Casting Institutes’s 2012 casting contest.
The near net shape configuration minimizes machining requirements; the thin-walled construction with finned walls assure superior heat dissipation.
The one-piece thin-wall construction features three integral net shape card guide bays. The staggered fin design allows for taller fins spaced closer together for increased heat transfer.
With challenging profile tolerances required throughout, an elaborate inspection fixture was necessary to inspect critical features.
