Process for the production of a porous pressed part
To improve the homogeneity of the porosity of a concave-convex pressed part with minimized mass, a pre-compressed pressed part with plane frontal surfaces is produced in a first process step. This part is then further compressed to produce a concave-convex sintered pressed part in a further process step. The pressed part can, however, also be produced in only one process step, if the requirements for homogeneous porosity distribution are less.
