  • Method of manufacturing electroformed components
    Patent number: 10370769
    Abstract: In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.
