Abstract
PURPOSE:To reduce the absolute quantity of a material of noble metal, and also to sufficiently compensate for thickness of a noble metal of a contact part, by seaming chips of constant length of a noble metallic wire and a base metallic wire whose diameter is larger than that of said wire, at the cut parts of both wires, and after that, working the header. CONSTITUTION:A noble metallic wire X such as white gold, gold, silver, etc., and a base metal wire Y of copper, etc. whose diameter is larger than that of said wire are cut to constant length. These chips Xa, Ya are butted at their cut parts and are hot-seamed. Subsequently, they are pressed by upper and lower metallic molds A, B for working the header, intermediate products Xb, Yb are formed and the final finished products Xc, Yc are formed by the second process. As a matter of course, these finished products Xc, Yc are larger than the outside diameters Sc, Rc of the worked products Xc, Yc, and also the outside diameter Rc is larger than the original outside diameter R. Also, when the ratio of wires X, Y is varied, the border line of both the wires can be varied.
