  • Publication number: 20170104200
    Abstract: Disclosed is a method of fabricating terminal plate materials according to an exemplary embodiment of the present invention. The method of fabricating terminal plate materials includes: a first drawing process of making a metal wire pass through a first die having a circular hole with a smaller diameter than the metal wire to generate a first metal drawing material having a cross-sectional shape, which corresponds to the circular hole; a rolling process of making the first metal drawing material generated by the first process pass between at least two rollers that rotate to generate a metal rolling material; and a second drawing process of making the metal rolling material pass through a second die having a predetermined cross-section to generate a second metal drawing material having a cross-sectional shape, which corresponds to the predetermined cross-section.
