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.
