The study provides adequate evidence that volume production of automotive turbine wheels investment cast in nickel base alloys is both feasible and within the current state of the art. The study has generated a logical process for mass producing investment cast turbine wheels and also provides the necessary capitalization requirement to support such a manufacturing capability. The cost analysis supports the original premise of an 80%-20% material to labor ratio. In addition the capitalization, manloading and resultant overhead considerations are well within automobile industry standards. The O.E.M. selling price per turbine wheel mass produced at the projected study levels would be approximately $10.04 to $12.15 each dependent on alloy selection. The capitalization of a facility to investment cast 2,000,000 turbine wheels per year would cost approximately $12,000,000 to $15,000,000, dependent on alloy selection.
