DEVICE AND METHOD FOR MOLDING METAL SEPARATOR

[Problem] To provide a device and method for molding a metal separator whereby distortions created during press molding are removed and the metal separator can be molded without any residual distortions. [ Solution ] A device (100) for molding a metal separator (91) by press-molding a thin plate-shaped base material (90) by means of a channel-processing upper die (31) (first die) and a channel-processing lower die (32) (second die) capable of moving towards and away from each other, the device having a first heating part (10) (heating part) for heating the thin plate-shaped base material, a channel-processing part (30) (processing part) for pressing the thin plate-shaped base material heated by the first heating part using the first die and the second die to form channels (90c) through which a medium flows, and a controller (180) for controlling the operations of the first heating part and the channel-processing part.
