A method for manufacturing pressed parts from hard metal, ceramic, sintered metal or likewise, in which a part of a charge of a powder-like or granular original material is filled into a pressing mould and is pressed with at least one pressing stamp against a counter surface, wherein the force and the distance of the pressing stamp are measured, and wherein there are the following method steps:

Method and device for manufacturing pressed parts from hard metal,

A method of monitoring maximum pressing forces of a pelletizing machine provided with a rotatable matrix disc and plungers, involves the steps of supplying values corresponding to pressing forces applied by plungers for evaluation in a computer so as to control a deviating device, detecting a position of the matrix disc continuously by an angle pulse transmitter and releasing pulses by the latter to supply the pulses to the computer, and coordinating the pulses with predetermined maximum pressing force values and supplying to evaluation. The pelletizing machine has a rotatable matrix disc, plungers whose maximum pressing forces are supplied for evaluation, a computer to which the maximum pressing forces of the plungers are supplied for evaluation, and an angle pulse transmitter supplying pulses released by the matrix disc during its rotation into the computer for an association to measured maximum pressing forces.
