Method for manufacturing a nozzle piston, production method for a damper, nozzle piston, damper, production plant for producing a damper

A method for producing a damper, the method comprising at least the following steps:

• a. producing a piston blank,
• b. introducing at least one recess into the piston blank by ultrashort pulse lasering, wherein the at least one recess, upon arrangement of a nozzle piston in a damper chamber, defines a nozzle for a damping fluid for adapting the flow impedance for the damping fluid between a first fluid chamber and a second fluid chamber,
• c. installing the nozzle piston in the damper chamber of the damper, wherein the nozzle piston is guided along a longitudinal axis of the damper chamber and divides the damper chamber into the first fluid chamber and the second fluid chamber,
• d. testing the nozzle piston, with respect to a force-velocity characteristic of the damper containing the nozzle piston, and
• e. controlling the step of introducing the at least one recess into a subsequently produced piston blank based on a result of the step of testing of the nozzle piston.
