Abstract (en)
[origin: US4389362A] A method for manufacturing an article to an intended near final shape and size with powder as the starting material. The powder is placed in a first capsule having the shape of the desired article and a size which allows for a suitable decrease in volume when pressing the powder into a solid body. This first capsule is placed in a second larger capsule and is surrounded on all its sides by a medium which is viscous at the compression temperature. The second outer capsule with its contents is heated, inserted into a press chamber, and surrounded by a readily deformable heat-insulating material such as talcum powder. A piston is inserted into the press chamber and acts to generate a pressure which compresses the material in the first capsule into a homogeneous, solid body.
