Abstract

Provided is a method for the production of a nozzle piston for arrangement in a damping space of a damper, which contains a damping fluid, wherein the piston divides the damping space into a first fluid chamber and a second fluid chamber. Also provided is a production method with the method according to the invention for a damper. Also provided is a nozzle piston for arrangement in a damping space of a damper, which contains a damping fluid, wherein the nozzle piston can be obtained by means of ultra-short pulse lasering of the recess from a piston blank. Also provided is a damper having a nozzle piston according to the invention. Also provided is a production plant for the production of a damper having at least one ultra-short pulse laser station for machining a piston blank for the damper by ultra-short pulse lasering.
