  • Publication number: 20110233378
    Abstract: An apparatus for casting material has a die for receiving a compressive force, the die having a shaped-opening for receiving a die insert. The die insert has an exterior shape that is adapted to cooperate with and be received in the opening such that compressive forces impinging upon the die are focused upon the die insert such that tensile forces within the die and impinging upon the die insert are minimized.

  • Patent number: 7882885
    Abstract: Systems and methods for reducing the potential for riser backfilling during investment casting are provided. In this regard, a representative method for performing investment casting includes: providing a mold having an opening communicating with an interior, the interior having a part cavity and a riser; providing an insert; and using the insert to form a physical barrier to reduce a potential for molten metal to backfill into the riser while the molten metal is introduced into the interior of the mold via the opening.

  • Patent number: 7866371
    Abstract: A method of forming a gating fixture for a lost wax casting process includes determining an optimal orientation of a gate in relation to a part, and forming a fixture that can repeatably be used to consistently locate the gate relative to the part. In one example, stereolithography is used to form the fixture.

  • Publication number: 20100084106
    Abstract: A molding process utilizes a seed with a columnar grain structure for defining a desired grain structure in a completed casting. The seed is received within a seed cavity of a mold. The molten material adopts the orientation of the columns defined within the seed during solidification to form a completed molded article having a desired columnar grain structure.

  • 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.

  • 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.
