Abstract:
1. A method for manufacturing a tip of a micro nozzle for producing a spray with a homogenous spatial droplet distribution having an orifice with a diameter of up to 2 mm and an inner section extending to the orifice comprising the steps of: forming a central cavity within the tip having a smaller size in the orifice section than the finished orifice; and performing a shaping operation of the orifice and of at least a portion of the inner section extending to the orifice in the same setup, whereby a smooth transition between the orifice and the inner section extending to the orifice is obtained and the longitudinal axis of the orifice is substantially concentric with the longitudinal axis of said portion of the inner section extending to the orifice so that the error of concentricity is less than 0.02 mm.
