Abstract: A system and method for more consistent joule heating of a material blank to a desired temperature. An electrical terminal delivers a current to an end portion of the blank. The terminal has a heat sink effect which would otherwise prevent the end portion from reaching the desired temperature. An active thermal buffer element is interposed between the terminal and the end portion. The buffer element includes a first surface which abuts the end portion and a second surface which abuts the terminal. The buffer element is joule heated with the blank, and a temperature gradient is created across the buffer element such that the first surface is at the desired temperature and the second surface is at a lower temperature due to the heat sink effect of the terminal. The buffer element thereby compensates for the heat sink effect and allows the end portion to reach the desired temperature.
