Abstract:
The invention relates to a method for producing a sintered part having a highly precise molded part height, the sintered part being produced from a first sintered joining part that has a first joining surface and a second sintered joining part that has at least a second joining surface. The method comprises at least the following steps: joining the first sintered joining part and the second sintered joining part, the first joining surface being oriented such that it faces the second joining surface; pressing the first sintered joining part and the second sintered joining part against each other under axial compression pressure exerted by a pressing tool, the highly precise molded part height being brought about by pressing the parts against each other; removing the sintered part from the pressing tool as a sintered part having a highly precise molded part height. The invention also relates to a parts set of sintered joining parts.
