ABSTRACT:
An electroforming process in which parts of complex configurations can be formed more effectively than with the processes available in the prior art. In particular, a heat shrinkable tube is positioned on a mandrel, the mandrel being of a shape different from the ultimate part to be formed but which will develop the desired shape for the part when shrink tubing is shrunk onto the mandrel. A layer of metal is then deposited over the tube and the mandrel is then removed. The tube is heated again, shrinking to a smaller size which enables it to be removed from the finished part.
