Title (EN) NOZZLE AND METHOD OF MAKING SAME
(FR) BUSE ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)Nozzle and a method of making the same are disclosed. The method includes (a) providing a microstructured mold pattern defining at least a portion of a mold and comprising a plurality of replica nozzle holes and replica planar control cavities; (b) molding a first material into a nozzle forming microstructured pattern using the microstructured mold pattern, with the nozzle forming microstructured pattern comprising a plurality of nozzle hole forming features and planar control cavity forming features; (c) forming a second material into a nozzle pre-form using the nozzle forming microstructured pattern, with the nozzle pre-form comprising a plurality of nozzle pre-form holes and sacrificial planar control cavities; and (d) forming a nozzle from the nozzle pre-form, said forming the nozzle comprising removing enough of the second material to remove the sacrificial planar control cavities so as to form a top surface of the nozzle pre-form into a planar top surface of the nozzle, and to form each of the nozzle pre-form holes into a nozzle through hole.
(FR)Le procédé consiste à (a) utiliser un motif de moule microstructuré définissant au moins une partie d'un moule et comprenant une pluralité de trous de buse répliqués et de cavités de commande planes répliquées; (b) mouler un premier matériau dans un motif microstructuré de formation de buse à l'aide du motif de moule microstructuré, le motif microstructuré de formation de buse comprenant une pluralité d'éléments de formation de trous de buse et d'éléments de formation de cavités de commande planes; (c) former un second matériau dans une préforme de buse à l'aide du motif microstructuré de formation de buse, la préforme de buse comprenant une pluralité de trous de préforme de buse et de cavités de commande planes sacrificielles; et (d) former une buse à partir de la préforme de buse, ladite formation de la buse comprenant le retrait de suffisamment de second matériau pour retirer les cavités de commande planes sacrificielles de façon à former une surface supérieure de la préforme de buse sous la forme d'une surface supérieure plane de la buse, et de façon à former chacun des trous de préforme de buse sous la forme d'un trou traversant de buse.
