Abstract

This invention relates to an electroforming device and a process used to electroform a metal layer on an inner surface of a female mandrel. The electrolytic solution flows only through an electrolytic solution passageway that defines the inner surface as the walls of the passageway. The mandrel may include more than one electrolytic solution passageway, or multiple mandrels may be used in a sequential order to mass produce the electroforms.
