  • Investment casting cores and methods
    Patent number: 7673669
    Abstract: To manufacture a casting core, one or more recesses are formed in at least one face of metallic sheetstock. After the forming, a piece is cut from the metallic sheetstock. The piece is deformed to a non-flat configuration.
    Type: Grant

  • Investment casting cores and methods
    Patent number: 7278463
    Abstract: An investment casting pattern is formed by forming a metallic first core element including at least one recess. The first core element is engaged to at least a mating one of an element of the die and a second core element. The recess serves to retain the first core element 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 may be pre-formed prior to cutting the first core element from a larger sheet of material.

  • Investment casting core methods
    Patent number: 7270170
    Abstract: A sacrificial core is used for forming an interior space of a part and includes a ceramic core element and a first core element including a refractory metal element. The ceramic core element may be molded over the first core element or molded with assembly features permitting assembly with the first core element.

  • Investment casting
    Patent number: 7216689
    Abstract: Pre-molding of wax or similar sacrificial material over one or more cores facilitates a subsequent molding over a core assembly. Individual cores or groups thereof may be pre-molded in a wax body. One or more such wax bodies may be assembled with other bodies and/or other cores to facilitate a main wax molding of such assembly.

  • Methods for manufacturing investment casting shells
    Patent number: 6951239
    Abstract: An at least two step heating process is used to strengthen the shell of an investment casting mold including a refractory metal core. The first stage may occur under otherwise oxidizing conditions at a low enough temperature to avoid substantial core oxidation. The second stage may occur under essentially non-oxidizing conditions at a higher temperature.
