Abstract
Method for producing a spray wall drilled with a network of holes for the pressurised fluid substance to pass through so as to be sprayed in fine droplets. The method includes the steps of (a) moulding a nozzle having a front wall integrally formed with an assembly wall, the assembly wall surrounding the front wall, the front wall having a curved initial configuration upon removal from the mould; (b) drilling the curved front wall with a network of holes having a defined initial orientation; and (c) deforming the drilled curved front wall into a final spray configuration defining a spray wall, the defined initial orientation of the holes being subsequently modified.

A method of manufacturing a spray wall that is drilled with holes through which the pressurised fluid product passes so as to be sprayed in small droplets, the method comprising the following steps:
- a—moulding a comprising a front wall and an assembly wall that are integrally formed, the assembly wall surrounding the front wall, the front wall having a curved initial configuration upon removal from the mould,
- b—drilling the curved front wall with a network of holes having a defined initial orientation,
- c—deforming the drilled curved front wall into a final spray configuration defining a spray wall, the defined initial orientation of the holes being subsequently modified.
A nozzle comprising a spray wall and a assembly wall integrally formed, the assembly wall surrounding the spray wall, the spray wall being obtained from an initially curved front wall that has been drilled with a network of holes, and then deformed into a final spray configuration that defines a spray wall, the initial orientation of the holes being subsequently modified,
- wherein the spray wall has a thickness in the range from 0.01 mm to 1 mm, advantageously from 0.05 mm to 0.2 mm.
