    摘要: An investment casting pattern is formed by forming a metallic first core element (50) including at least one recess (34). The first core element (50) is engaged to at least a mating one of an element (60) of a die and a second core element. The recess (34) serves to retain the first core element (50) relative to the mating one. The die is assembled and a sacrificial material is introduced to the die to at least partially embed the first core element. The recess (34) may be pre-formed prior to cutting the first core element (50) from a larger sheet of material.

    摘要: Pre-molding of wax or similar sacrificial material over one or more cores (20) facilitates a subsequent molding over a core assembly (110). Individual cores or groups thereof may be pre-molded in a wax body (90). One or more such wax bodies (90A, 90B, 90C) may be assembled with other bodies and/or other cores (110) to facilitate a main wax molding of such assembly in a die (112).
