TVJ ElectroformingA division of Dover Industrial Chrome, inc |
| TVJ Electroforming, a division of Dover Industrial Chrome, Inc. since 1989, was also founded in 1945. Three men, using their first initials, founded their company as the T. V. Jay Company. When purchased by Dover, the divisional name was chosen to emphasize the principal type of work performed. Electroforming, done primarily in nickel and in copper, is also done in silver, lead, tin, and even gold. Electroforming is essentially like electroplating continued to a thickness such that the plated metal can support itself when removed from the base substrate or mandrel. Electroforming is a means of manufacturing highly complex shapes that would be impossible or impractical to create by other means. The form is entirely dependent upon the shape of the substrate or mandrel as it is often called. Mandrels may be made of wax, plastic, rubber, aluminum, or passivated stainless steel, with separation being made by melting, dissolving or physical force. Optical chambers and mirrors; ducts, often with varying diameter and sometimes with multiple ports; molds for rotational molding or mold inserts for injection molding; works of art --- are examples of typical electroformed products.
