Abstract: A method for producing a sintered part, having at least the following steps: a) providing a sintered part, said sintered part having a first end face, a second end face arranged at a distance from the first end face in an axial direction, and a circumferential surface between the end faces; b) arranging the sintered part in a tool; c) applying a first pressure force, which acts on the end faces at least in the axial direction, to the sintered part by means of the tool; and d) applying a second pressure force, which acts on the circumferential surface at least in a radial direction, to the sintered part, wherein the sintered part is reshaped at least by the second pressure force, or mechanically processing the sintered part. Steps c) and d) are carried out at least partly simultaneously.

Abstract: A sintered part has at least one base with a first end face which faces in a first axial direction and a second end face which faces in a second axial direction. The end faces are produced in a press for producing a green body (which is subsequently sintered to form the sintered part) by applying at least one punch which can be moved along the axial directions. The sintered part has an elevation extending from the first end face towards one end at least in the axial direction over a first height, and the elevation has a first width extending transversely to the axial direction in a radial direction and at least some portions of which are smaller than 0.8 millimeters, wherein at least some portions of the sintered part have a first density along the first width, said density equaling at least 87% of the full material density.

Abstract: The present invention relates to a punch unit of a powder press, wherein the punch unit is assembled from at least two parts, in this case comprising a headpiece as the first part and a widening region, adjoining the headpiece, as the second part, wherein the widening region flares to a diameter of a punch bolder which is directly attachable to an end, located away from the headpiece, of the widening region. Furthermore, punch units of a powder press that slide one inside another, a powder press itself and a method for operating a powder press are proposed.

Abstract: A powder press is proposed with a die construction which has a conical lower ram (UE) with lower rams which are nested inside one another, wherein each lower ram has a longitudinal extent, in particular a cylindrical longitudinal extent, which is guided by way of a template (M), wherein a conical widened portion adjoins preferably every longitudinal extent, wherein a respective cone angle of the lower ram preferably increases from the inside to the outside.
