    • The invention relates to a method for producing a moulded part from a disk-shaped or plate-shaped base body (5) comprising a plurality of knot-shaped and/or ridge-shaped elevations (4, 3) which merge into the base body (5) with inclined lateral surfaces, by pressing and sintering powdery starting materials into a shape that is close to the end shape. According to the invention, the pressing takes place in a two-step pressing process. In the first pressing step, the defining surfaces of the base body (5) are pressed up to the elevations (3, 4), in order to form an at least approximate end shape, and the elevations (3, 4) are simultaneously pressed with overdimension. The projection h of the elevations (3, 4) in relation to the base body (5) is 10 % to 150 % higher than the projection h' in the finished pressed state. The lateral surfaces form an angle of inclination alpha ' between 90 DEG and 150 DEG with the respectively adjacent defining surface of the base body (5). In the second pressing step, the elevations (3, 4) are pressed to form an at least approximate end shape, the angle of inclination
