Abstract
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 mould.
Claims4
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.
