  • Polymeric mandrel for electroforming and method of electroforming
    Patent number: 4158612
    Abstract: An electroforming mandrel providing exceptional resistance to mask removal in highly corrosive electrolytes. The mandrel relies on a molecular bond between a non-conductive polymer mask and the electrically conductive polymer plating surface to avoid separation of these members and to allow multiple reuse. A metal core acts as a structural member and serves to uniformly distribute current to the electrically conductive polymer.
