摘要： The objective of the present invention is to provide a method for forming protrusions, a system for forming protrusions, and a method for manufacturing a metal component having the protrusions, in which the protrusions can be easily formed by press molding without making the metal plate thinner, or without deforming the metal rod or reducing the diameter thereof, in relation to metal plates or metal rods having protrusions to be used for components or current collecting terminals of various devices, and so on. Solid metal protrusions are formed by the method comprising: clamping and fixing the metal workpiece with a support die and a pressure die; pressing each cross section of an outer peripheral end parts of the metal workpiece fixed with the support die and the pressure die at a temperature lower than a softening point of a metal used as the metal workpiece from a direction perpendicular or oblique to an upright direction of the protrusions to be formed on one surface of the metal workpiece by press molding using a pressing die or a pressing jig; undergoing plastic flows of metal into through-holes formed as recessed parts that serve as female molds for forming the protrusions in at least one of the support die and the pressure die; and forming solid protrusions on the surface of the metal workpiece.
