The invention relates to a process for determining pressing parameters for the pressing of compacts, whereby in one step a test compact is brought to the required density in order to achieve the nominal pressing force, and in order that consequently the machine is in a balanced deflected condition with regard to this nominal pressing force. In next step, in case a nominal height (hsi,Nominal) deviates from a height (hsi,Measure) measured on the test compact, there will be determined for the next pressing operation a required height (HPowderNew) of the material to be pressed in the pressing mold. By determining the density of the compact in a deflected condition of the pressing device, there can subsequently be calculated in a simple way the required difference in quantity of powder for achieving a desired height of the individual segments of the compact.
Process for determining pressing parameters for pressing of compacts from a basic material to be pressed, in which the height of a test compact is set only after a nominal density has been achieved.
Process for determining pressing parameters for pressing of compacts (9) from a basic material to be pressed, with the steps:
Process according to any preceding claim, wherein determination of the new height of pressing material (HPowderNew) is carried out after having achieved the nominal density (PNominal) as product of the height of pressing material (HPowderOld) used last time times the quotient of nominal height (hsi,Nominal) and measured height (hsi,Measure).
Process according to any preceding claim, wherein the comparative measurements, comparisons and new determinations for different segments (S1-S3) of compacts (9) of complex shape are carried out for each segment (S1-S3).
Device for automated determination of pressing parameters for pressing of compacts from a pressing material, comprising
Process or device according to any preceding claim, wherein the basic material to be pressed, respectively the pressing material, is a granulate or powdery material.
