Abstract:
An electroforming method for making metal products having a pattern of openings separated by dykes using an electroforming mandrel in an electroplating bath, wherein metal from the electroplating bath is deposited on the mandrel, comprising:a.) providing the electroforming mandrel, including at least two electrically conducting regions electrically insulated from one another, said regions comprising at least one main pattern for product dykes to be formed, which main pattern is electrically insulated from at least one ancillary pattern for a reinforcement to be formed;b.) connecting the ancillary pattern to a current source;c.) electroforming to form a reinforcement on said ancillary pattern to effect an electrical connection between the ancillary pattern and the main pattern by grown metal; and,d.) continuing electroforming in order to thicken the reinforcement and to form product dykes.
