Abstract (en)

Hot isostatic pressing apparatus wherein a material to be processed such as preliminarily shaped metal powder is charged into a high pressure vessel (1027) provided with a heater (1029) and the material to be pressed by superhigh pressure of fluid or gas sealed into the vessel and heating by a heater. The apparatus comprises a main station (1026) including a high pressure vessel (1027), a movable cover (1033), a member for moving the material to be processed; one or more auxiliary stations including an inserting station, a prehating station, a removing station, all joined to a sealed tank (1001); and transfer means for the material to be processed. The apparatus also includes a seal leakage detector.

A continuous hot isostatic pressing appts. has a main station with a hot isostatic pressing and forming high pressure vessel with a movable cover, an inserting station and a removing station for material to be processed, and a sealed tank which communicates with the vessel and operating chambers of the stations.
