Abstract:
A process for determining pressing parameters for pressing compacts from a basic material, comprising:pressing a basic material of a first height to form a first test compact; measuring a density of the first test compact; if the density of the first test compact is outside a predetermined tolerance value of a nominal density, pressing a basic material of a second adjusted height to form a second test compact; repeating said density measuring and pressing one or more additional times if the second or subsequent test compact density is outside said predetermined tolerance value of a nominal density to produce a test compact within said tolerance value of said nominal density; measuring a height of the test compact that has a density within the tolerance value; if a nominal height and the determined height do not coincide within a predetermined tolerance value of the nominal height, pressing a basic material of another adjusted height to form an additional test compact; and repeating said height measuring and pressing one or more additional times if the additional or subsequent test compact height is outside said predetermined tolerance value of a nominal height to produce a test compact within said tolerance value of said nominal height.
