The present invention relates to an isostatic press device which compression-molds a workpiece to be processed by applying isostatic pressure to the workpiece. The isostatic press device according to an embodiment of the present invention comprises: an inner vessel which is formed in a columnar shape and has a receiving groove for receiving a workpiece to be processed, the receiving groove being formed at a middle portion of the inner vessel and passing therethrough in the width direction; an outer vessel having an insert hole formed therein, into which the inner vessel is slidably inserted, to seal the part of the receiving groove of the inner vessel; a sealing member for sealing a portion between the inner and outer vessels; and a pressurizing medium providing mechanism that provides the receiving groove with a pressurizing medium for applying pressure to the workpiece received in the receiving groove. Therefore, isostatic press device has a relatively simple structure to reduce the manufacturing costs thereof, and obtains a workpiece having a dense texture by heating and cooling the pressurizing medium in a short time, thereby minimizing the defect rate of the workpiece. |
