ABSTRACT:
An apparatus for manufacturing a sintered body with high density comprises: a table having an object to be processed laid thereon; a pressure vessel accommodating a heat element heating the object around and a heat-insulating mantle surrounding the heat element; supply device for supplying to the pressure vessel an extractant which extracts a binder or a dispersion medium contained in the object, exhaust device for exhausting the extractant and an extracted substance from the pressure vessel; pressure device for raising a pressure in the pressure vessel, and vacuum means for evacuating the pressure vessel. The apparatus enables carrying out the three steps of drying or degreasing, sintering and hot isostatic pressing of the object once put in the pressure vessel without handling the object outside the vessel. The object is formed as a compact in the preprocess in advance of being put in the apparatus.
