Abstract

In the process a hot-press mould is filled with powder of a metallic or non-metallic composition for the production of a sintered body and is hermetically sealed. The hot-press mould and the powder are heated to a temperature at which the hot-press moulding material flows in a plastic manner and the powder fuses by sintering. Then an external pressure is exerted on the entire outer surface of the hot-press mould in order to exert a hydrostatic pressure on the powder in the mould cavity and to compact said powder to form a sintered body. The volume of the mould cavity must not be larger than the total volume of the hot-press moulding material, in order to form around the mould cavity walls of such thickness that the outer surface of the walls does not closely follow the contour of the mould cavity. A high precision of the press moulding is thus obtained and the finishing is less complicated than in sintered bodies produced by known processes. <IMAGE>
