Abstract
A piston and a method for producing a piston which can be secured to a piston sliding unit is provided. The piston sliding unit can be moved along its longitudinal axis in a cylinder. The piston includes a disc-shaped base body, wherein the piston is suitable and intended to seal two regions of the cylinder filled with a medium against one another. The method includes the following steps: a) producing the piston by pressing a material into a piston mold; b) smoothing the surface of the piston and/or pressing at least one flow path into the piston, by an embossing tool, which has a raised and rotationally symmetrical structure.
