Abstract

Pressing powder material into a blank of prescribed thickness comprises measuring or calculating the deformation of the die plate for different pressing forces and tabulating the correlating value in a computer; and acquiring the deformation during pressing using the measured deformation forces on the table and correcting the adjusting path of the upper and lower stamp according to the measure of the deformation. Preferred Features: The deformation force is continuously acquired during the pressing process.
