Method for producing a piston and piston

A method for producing a piston, wherein the piston is attachable to a piston sliding unit, wherein the piston sliding unit is movable along its longitudinal axis in a cylinder, wherein the piston has a disc-shaped base body, wherein the piston is suitable and intended to seal two regions of the cylinder filled with a medium against each other, and wherein the piston comprises an annular piston collar,

• the method comprising the steps:
• a. producing the piston by pressing a material into a piston mold;
• b. pressing at least one flow path into the piston by an embossing tool which has a raised and rotationally symmetrical structure,
• wherein the raised and rotationally symmetrical structure of the embossing tool has at least one point of intersection with the annular piston collar when placed on the piston,
• wherein the raised and rotationally symmetrical structure of the embossing tool crosses the annular piston collar from a side facing a piston center to a side facing away from the annular piston center at the at least one point of intersection, and
• wherein the annular piston collar is at least partially pressure-formed into a flattened and/or recessed shape by pressing the raised and rotationally symmetrical structure into the piston at the at least one point of intersection.
