CA 2348429

The invention relates to a method for producing a sintered part (1) comprised of a powdery material, especially comprised of a sintered metallurgical powder. According to the inventive method, a green compact which forms an elementary shape of the part is firstly compression molded from the powder. The desired final shape of the part is produced by subjecting partial areas (3) of the elementary shape on the green compact to a successive non-- cutting shaping. Afterwards, said final shape is finished by sintering.

L'invention concerne un procédé pour la production d'une pièce frittée (1)constituée d'un matériau pulvérulent, notamment d'une poudre de métal frittée. Selon ce procédé, une ébauche est tout d'abord formée à partir de la poudre, ladite ébauche constituant la forme fondamentale de la pièce. Ensuite, la forme finale souhaitée est produite par au moins une opération de formage ultérieur de zones partielles (3) de la forme fondamentale de la pièce, sans enlèvement de matière, avant la réalisation du frittage.
