Disclosed is a method for producing substantially axially symmetrical workpieces by shaping a starting material (3) with the aid of a die (1) and a rotatable tool (2), the die (1) being provided with a bore (11) along the central axis thereof. The inventive method comprises the following steps: the starting material (3) is introduced through the bore (11) of the die (1); and the starting material (3) is pressed in between the die (1) and the rotating tool (2) such that the starting material (3) flows outward from the central axis according to the contour of the die (1).
L'invention concerne un procédé de production de pièces sensiblement à symétrie de rotation par formage d'une matière de base (3) à l'aide d'une matrice de façonnage (1) et d'un outil rotatif (2). La matrice (1) présente un orifice (11) le long de son axe central. Ce procédé consiste à introduire la matière de base (3) dans l'orifice (11) de la matrice (1), et à comprimer la matière de base (3) entre la matrice (1) et l'outil (2) qui tourne de telle façon que la matière de base (3) s'écoule vers l'extérieur à partir de l'axe central conformément aux contours de la matrice (1).
