Abstract
PURPOSE:To prevent peeling of a contact point part from a base part in the stage of producing a composite electric contact point consisting of a Cu base and an Ag alloy contact, by restraining the abutting surfaces of both metals in a metal mold without exposing these to space and deforming these plastically. CONSTITUTION:In the stage of producing a composite electric contact point material consisting of a Cu base and an Ag of Ag alloy contact part, an Ag alloy short wire rod 9 for the contact part having a diameter approximately equal to the diameter of the inside wall 2 of a metal mold 1 and a Cu short wire rod 10 for the base part are put into the metal mold 1. A pin rod is advanced to press the rod 9 into a die cavity 6, and to press the leading end of the rod 10 simultaneously. Both short wire rods form the part in contact with the inside wall of the mold and the part not in contact therewith, respectively. At this time, the pin rod 5 is retreated, and the pin rod 4 is advanced to press both rods 9, 10, whereby the parts in contact with the inside wall of the mold are plastically deformed and the both short wire rods are cold press stuck on the abutting surfaces.
