<p>This invention relates to a hot-pressing method and a hot-pressing apparatus capable of quenching a workpiece at a sufficient cooling rate. In a hot-pressing step, a hot-pressing apparatus presses and cools a workpiece at the same time. The hot-pressing apparatus includes a lower die and an upper die whose forming surfaces face each other. A top surface of the lower die is provided with a plurality of beads so that a part of the workpiece difficult to come in contact with the forming surface of the lower die and the forming surface of the upper die positioned at the bottom dead center is formed into a stepped shape.</p> |
