Abstract (en)

[origin: WO2021116391A1] The invention relates to a sintered part (1) which is made of a metal material and is produced by compacting a particulate metal material in order to form a green body (2) and subsequently sintering same. The sintered part (1) has at least one base (3) with a first end face (5) which faces in a first axial direction (4) and a second end face (7) which faces in a second axial direction (6), said end faces being produced in a press (8) for producing the green body (2) by applying at least one punch (9) which can be moved along the axial directions (4, 6). The sintered part (1) has an elevation (12) which extends from the first end face (5) towards one end (10) at least in the axial direction (4, 6) over a first height (11), and the elevation (12) has a first width (14) which extends transversely to the axial direction (4, 6) in a radial direction (13) and at least some portions of which are smaller than 0.8 millimeters, wherein at least some portions of the sintered part (1) have a first density (15) along the first width (14), said density equaling at least 87% of the full material density.
