Abstract

A treatment chamber for heating and pressing workpieces and a heat insulating structure which covers the treatment chamber sideways and from above are provided within a high-pressure vessel. Below the treatment chamber are disposed a base heater for heating a pressure medium gas and a fan for supplying the pressure medium gas in a heated state into the treatment chamber and stirring the heated gas. The workpieces can be held on the heat insulating structure side, and the heat insulating structure and the workpieces can be taken out from the interior of the high-pressure vessel and can be conveyed together separately from a lower lid of the high-pressure vessel. A hot isostatic pressing apparatus is provided less expensively which can heat and press workpieces at a relatively low temperature of not higher than 600° C. Besides, it is possible to shorten the cycle time in HIP.
