    摘要： A process for compacting powdered material to form a compact of a predetermined thickness and having at least one lateral oblique surface by means of a bore in a die bolster for receiving the powdered material and an upper ram and a lower ram, which are operable by means of a hydraulic power-exerting device and are positionable by means of a control device with respect to the die bolster, comprising the following steps: The deformations of the die bolster are measured or calculated for various compacting forces and the correlating values are filed as a table in a memory with the deformations forces being determined from the difference of the compacting forces of the two rams, and Deformation is determined during the compaction procedure by applying the deformation force measured to the table and the feed length of the upper and lower rams is corrected depending on deformation.
