<p>A press device according to an embodiment of the present invention comprises a first chamber at a press surface side and a second chamber at the other side, which are separated by a flexible sheet, and a pressure control system for controlling an inner pressure difference between the first and second chambers, and lowers an inner pressure of the first chamber to be relatively lower than that of the second chamber, such that a workpiece to be processed is inserted between the press surface and the flexible sheet, and press-formed. The pressure control system includes an exhaust pipe for discharging air from at least one among the first chamber and the second chamber, and an air supply pipe for supplying air to at least one among the first and second chambers.</p> |
