Abstract: In this paper, an effective method is presented to improve thickness uniformity in nickel electroforming process. In most electroforming, processes, thickness ratio of edge to center is 2.5 similar to 4 and the shape of the electroforming zone is naturally a concave. Dividing conductive zone of electroforming structure to redistribute current density was applied to improve electroforming uniformity. Theoretical analysis and experimental results verify that a proper dividing method can improve the electroforming uniformity effectively. In the experiment, the thickness ratio of edge to center decreases from 2.91 to 1.88.
