Abstract:
The invention relates to a process for producing a molding, comprising a disk-like or plate-like basic body -5- having a large number of knob-like and/or web-like elevations -4-3- which merge into the basic body -5- with inclined side surfaces, by means of pressing and sintering powdery raw materials close to the final shape.According to the invention, the pressing is carried out in a two-stage pressing operation. In the first stage the boundary surfaces of the basic body -5- are pressed to at least the approximate final shape as far as the transition regions of the elevations -3-4- and, at the same time, the elevations -3-4- are pressed to an oversize. The projection h′ of the elevations -3-4- from the basic body -5- is greater by 10%-150% as compared with the projection h from the basic body -5- in the finally pressed state. Their side surfaces form an angle of inclination α′ in the range from 90°-150° with the respectively adjacent boundary surface of the basic body -5-. In the second stage, the elevations -3-4- are pressed to at least approximately the final shape, the angle of inclination α′ being enlarged to a value α which lies in the range from 95°-170°.
