Abstract: In a method for producing a spray nozzle device, in particular for spraying a casting strand during casting of metallic products, the spray nozzle device includes a basic body with an air inlet, a water inlet and a nozzle body with a mixing chamber for producing an air/water mixture which emerges through at least one nozzle outlet. The air inlet is formed by at least one air inlet nozzle, with a nozzle tip projecting into the mixing chamber, and has at least one air outlet hole. The water inlet opens into the mixing chamber close to the nozzle tip of the air inlet through at least one water outlet hole oriented transversely to a longitudinal axis of the mixing chamber. At least one part region of the spray nozzle device is produced by a generative production process, preferably operating as a 3D printing process.
