Electroforming

Electroforming is the process by which articles or shapes can be exactly reproduced by electrodeposition on a mandrel or form that is later removed, leaving a precise duplicate of the original. This article discusses electroforming applications, and explains electroforming of nickel, cobalt, iron, and copper, providing information on mandrel design and selection, electroforming solutions and operating variables. It discusses the significant aspects of electroforming that demand special considerations, such as metal distribution, internal deposit stress, roughness, and treeing. The article concludes with an overview of alloy electroforming.
