Abstract
A method for producing a sintered component in the form of a workpiece having teeth, wherein crowning, with a central region and end regions, is formed in flanks of teeth, the tooth thickness being smaller in at least one of the end regions than in the central region of the flanks. In order to form the crowning, at least one pressing punch acts on the teeth, which are located in a die, along a first axis such that the teeth are sized at least to the central region by means of axial pressing.
