Abstract
First of all, an element determining the shape of the cavity is embedded in the powdered metal, the material of the element (37) having the property of being absorbable by the metal powder. The material of the element (3) is, furthermore, chosen in such a way that the element (3) maintains its shape during isostatic compaction at a pressure between 2000 and 8000 kg/cm<2>. Subsequent sintering is carried out in such a way that the wall of the cavity is saturated evenly and completely with the material of the element (3). The method can be used to manufacture a sintered product having cavities of any shape required, the walls of said cavities being leakproof. <IMAGE>
