  • Systems and Methods for Undercut Features on Injected Patterns
    Publication number: 20140284016
    Abstract: A method for creating undercut features in a wax pattern in an investment casting process is disclosed. The method comprises designing a tooling that includes a mold for an object with an aperture and a core corresponding in size and shape of the aperture. Then, the mold is used to injection mold a pattern for the object, wherein the pattern includes an opening corresponding to the aperture. Next, a plug from the core of the tooling is injection molded using the mold. The plug is press-fitted into the opening of the pattern and the opening of the pattern is sealed with the plug.
