Electroforming can be defined as a process that employs technology similar to that used for electroplating but which is used for manufacturing metallic articles, rather than as a means of producing surface coatings. The principles of the electroforming process are demonstrated in Fig.1. this shows a Suitable metal, such as nickel, being electrodeposited onto the surface of a conical mandrel (the term mandrel is used to describe the former onto which an electroform is grown). When the deposit has attained a sufficient thickness it is then separated form t he mandrel to become a metallic product with a totally independent existence.
