Further, since the workpiece is directly heated or cooled by the pressurizing medium, the workpiece can be heated or cooled at a uniform temperature.

Further, by heating or cooling the workpiece in a state in which the pressure is maintained, it is possible to obtain a workpiece having a dense structure, thereby minimizing the defective rate of the workpiece.

A heat insulating material 300 is installed inside the inner vessel 110 and the outer vessel 120 to prevent heat from being transmitted to the inside of the inner vessel 110 and the outer vessel 120 to prevent breakage of the sealing member 130, Can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
