METHOD AND DEVICE FOR PRESSING WORKPIECE

摘要

PURPOSE: A method and device for pressing a workpiece is provided to apply equal pressure over the workpiece regardless of the flatness of a press surface and to efficiently heat the workpiece. CONSTITUTION: A pressing device(100) including a platen(116) for pressing a workpiece has a pressing plate mounted between the platen and the workpiece to press the workpiece instead of the platen when the platen is moved toward the workpiece, and a liquid layer formed between the pressing plate and the platen to transfer force for pressing the workpiece with a required pressure to the pressing plate from the platen through the liquid layer. The platen is a heating platen heated to a temperature sufficient to heat the workpiece to a temperature required for pressing and the liquid layer is filled with heat transfer oil. The pressing plate is a metal plate with a mirror-finished surface.
