Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A microstructured pattern for forming a nozzle pre-form comprising a plurality of nozzle pre-form holes, sacrificial planar control cavities, with each nozzle pre-form hole having an outlet end and a sacrificial planar control cavity being disposed at the outlet end of each nozzle pre-form hole, said microstructured pattern comprising: a plurality of nozzle hole forming features that are substantially negative replicas of the nozzle pre-form holes, wit…
