Abstract: Provided are methods and apparatuses for processing objects by applying different forces and/or pressure levels to different portions of surfaces of these objects. An apparatus may include a flexible wall and a contact member. In some embodiments, the flexible wall forms a bladder such that the contact member is disposed inside the bladder. During operation, the flexible wall may be pressed against an object using a pressure differential across the wall (e.g., by pressurizing the bladder). This creates a first force acting on a first portion of the object surface. Furthermore, the contact member may be forced against the flexible wall and apply a second force to a second portion of the object surface through the wall. The second portion of the object surface may be a subset of the first portion or an entirely different portion.

Abstract: While a workpiece is heated and pressed by one of a pair of high-pressure vessels, a workpiece being pressed by the other high-pressure vessel is placed in a heated state. In the reducing process after termination of heating and pressing treatment of the workpiece by one high-pressure vessel, both the high-pressure vessels are placed in communication, and the pressure medium gas released from one high-pressure vessel is poured into the other high-pressure vessel. After pressures of both the high-pressure vessels have assumed a nearly balanced state, the pressure medium gas is sucked out of one high-pressure vessel by a compressor and pressed, and is poured into the other high-pressure vessel, and the workpiece is heated and pressed by the other high-pressure vessel. By the method as described, considerable shortening of cycle time of HIP treatment is achieved, and the HIP treatment can be carried out with high efficiency.
