Abstract
An approach for supporting a wax pattern during investment casting. The approach described herein forms a support structure to support the wax pattern during investment casting. The support structure has a capping structure with a geometry that can match a profile of a lower region of the wax pattern, and at least one support brace extending outward from the support capping structure. The support structure can be placed on a surface of the lower region. The support capping structure can form a defined envelope to enclose the lower region of the wax pattern. The support structure is connected to a base plate by the support brace(s). The capping structure and the support brace(s) secure the wax pattern to the base plate and distribute the load of the wax pattern to maximize strength while minimizing the risk of a discontinuity in the wax or shell that could affect the casting process.
