The production of steel castings is dominated by room temperature molds, primarily in sand mold cavity-making processes. Castability Geometry for those mold types has been well-defined in episodes 3, 4, and 5. However, a very significant sub-set of steel castings are poured in hot ceramic shell investment molds. This episode 6 addresses the differences in OEM Castability Geometry choices in design AND producer manufacturing engineering principles for the three steel alloy sub-groups… when produced as investment castings in hot molds.
Steel casting producers in the hot ceramic shell process typically pour a wide variety of ferrous alloys. Process-Dominated Castability Geometry explains why. Design and manufacturing engineering principles for hot ceramic shell molds are illustrated in models and simulations.
