Electroforming is an inverse process to chemical blanking, in which the metal is deposited inside a cast of conductive material, which reproduces in negative the image to be made. In this way it is possible to obtain a faithful reproduction of the original image through a metal deposit.
The advantages of electroforming
This technology offers the possibility of realizing very precise details, with tolerances of even a few microns, regardless of the complexity of the image. Furthermore, the details of the object do not have attachment points (as instead in photoengraving), they can be treated galvanically, and can be realized on several levels.
Technical details and materials
Electroforming is a more expensive and slower process than photoengraving, affected by the size and thickness of the detail, and is generally limited to the Nikel, hard or soft, in terms of materials.
