Abstract

L’invention concerne des procédés d’emboutissage ou de forgeage de pièces de métal réduites en poudre. Un exemple de procédé fait appel à une presse englobant une première tige, un premier coulisseau entourant la première tige, une filière présentant une cavité de filière, une seconde tige opposée à la première tige, et un second coulisseau entourant la seconde tige, la première tige et la seconde tige étant dimensionnées pour tenir dans le diamètre à l’intérieur de la pièce. Dans le procédé, la pièce est positionnée dans la cavité de filière, un élément parmi la première tige et la seconde tige est situé comme tige centrale dans le diamètre à l’intérieur de la pièce, et au moins l’un des éléments parmi le premier coulisseau et le second coulisseau se déplace vers l’autre élément parmi le premier coulisseau et le second coulisseau de telle sorte qu’à la fois le premier coulisseau et le second coulisseau se touchent puis estampent ou forgent la paroi de la pièce.
