Abstract

Producing pressed parts comprises pouring a predetermined amount of metal powder into a matrix bore (12) of a press; adjusting lower (16) and upper stamps (14) of the press in a predetermined first and/or second position; further adjusting the lower stamp and optionally the upper stamp and simultaneously measuring pressing force of the lower stamp; and stopping the adjusting movement of the lower stamp and optionally the upper stamp when a predetermined value for the pressing force is reached.
