Abstract

A method and a device for powder metallurgical manufacturing of an object, at which one or more thermoplastic films (3) are shaped against a die to a shaping barrier surface between a first fine particulate metallic or metallic and ceramic material, which after pressing and/or sintering is to constitute the shaped object, and a powder filling (12), consisting of a second fine particulate ceramic material or a mixture of a ceramic material and other materials, at which method the first fine particulate material (13) as well as the second fine particulate material (12) are placed in a tight container (8, 14, 16), said tight container (8, 14, 16) being heated to a temperature, at which the film or films (3, 11) are gasified, and the container (8, 14, 16) being evacuated so that the gasified film (3) is sucked out of the container. Preferably the first fine particulate material consists of substantially spherical and/or irregularly shaped particles.
