  • Electroforms with high dimensional stability
    Patent number: 5160421
    Abstract: An electroforming process is used to prepare an electroformed metal layer on the inside surface of a female mandrel to form an electroform with a hollow interior. A device may be positioned within the hollow interior of the electroform, and the interior is filled with a filling material. The electroform may then be separated from the mandrel by a force applied to the device positioned within the filling material.
