Eric Ehrhardt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12594597
    Abstract: A method for manufacturing an alloy component includes forming a mold including a first mold portion and a second mold portion defining a mold cavity therebetween. At least one of the first and second mold portions comprise one or more inserts disposed through an outside surface of a respective mold portion and extending through the respective mold portion proximate to the mold cavity. The method can include delivering a molten alloy into the mold cavity and supporting by the one or more inserts, the molten metal as the molten metal cools to form a part. The one or more inserts can comprise a plurality of hollow tubes extending therethrough, and can enable cooling and/or heating of the molten alloy and/or alloy part through the plurality of hollow tubes.
    Type: Grant

  • Publication number: 20250229325
    Abstract: A configurable end-effector is provided for a robotic system used in a casting process. The end-effector can have one or more ablate and/or cooling modules that can apply an ablating material and/or cooling fluid to a mold for the solidification or the solid to solid transformation of the metal component of the part to be cast or formed in the mold or tooling. The end-effector may incorporate one or more air push or vacuum modules that can be used to remove or move the ablate material phase state change and/or the cooling fluid after the ablate material and/or cooling fluid absorbs heat from the part. The end-effector can include one or more energy modules that can be used to introduce heat to the mold and/or tooling and the formed component part so that additional processes can be performed on the component part.
