Abstract

The invention discloses a press die for electrically assisted manufacturing performing plastic working at a relatively lower temperature than hot working by using an electroplasticity effect that a flow stress inside a material is reduced when a current is applied to the material, the press die for electrically assisted manufacturing including: an upper die and a lower die configured to be disposed at upper and lower portions, having the material disposed therebetween; and at least one electrode pair configured to be disposed in the upper die or the lower die, wherein the electrode pair is configured so that electrodes having different polarities in a width direction of the material face each other.
