Abstract

Spray device as well as a method for manufacturing an spray device, comprises assembling at least one spray nozzle plate into a thermoplastic holder, while controlling the temperature of the spray nozzle plate and/or the holder and as a result at least locally plastically deforming the holder permanently. After the thermoplastic deformation of a seat of the holder, a diameter of the seat of the holder upstream of the spray nozzle plate exceeds a diameter of the seat of the holder downstream of the nozzle plate. The thermoplastic holder may have a tapered seat, where the smallest cross section of the tapered seat is smaller than the spray nozzle plate, wherein the method may comprise: - heating the spray nozzle plate; - pressing the spray nozzle plate into the tapered seat of the holder by bringing the nozzle plate towards a smallest side of the tapered seat, thereby thermoplastically deforming a wall of the tapered seat; and - forming a spray device from an assembly of the spray nozzle plate and the thermoplastic holder, whereas a widest side of the tapered seat is pointing towards a supply side of the liquid
