Abstract
A system for producing a core including a core profile for use in casting. The system comprises a cavity block including an upper portion, a lower portion, and a recessed cavity in each of the upper portion and the lower portion; an adapter insert including a first portion and a second portion, the adapter insert sized to fit within the recessed cavity in each of the upper portion and the lower portion of the cavity block; and a core die insert sized to fit and be positioned within the adapter insert. The core die insert includes a sacrificial material and a hollow internal profile, with the hollow profile of the core die insert corresponding to the core profile.
