Abstract:
1. An isostatic press comprising: a heat insulator that forms a working zone which contains a workpiece, said heat insulator including a communication hole formed through a top portion of said heat insulator; a high pressure vessel that covers said heat insulator to form a space therebetween, wherein a pressure medium introducing space communicates with said working zone, and can introduce a pressure medium, said pressure medium introducing space is provided in a space between said heat insulator and said high pressure vessel; a heating unit that heats said high pressure vessel from outside of a body of said high pressure vessel, the heating unit includes a jacket which is provided on an outer periphery of said high pressure vessel, whereby heat from said jacket is transferred to said pressure medium introducing space through the body of said high pressure vessel; a pressure medium supplying device connected for supplying high pressure medium directly to the pressure medium introducing space, without directly supplying the high pressure medium to the working zone, wherein the pressure medium in said pressure medium introducing space communicates with said working zone by flowing through the communication hole, and said pressure medium supplying device communicates with said pressure medium introducing space via a pressure medium introducing opening formed on a bottom portion of said high pressure vessel.
