Ink Jet Nozzle

An ink jet nozzle or multijet nozzle plate may be formed by first forming a relatively large hole for each jet and then coating the interior with a layer of glass.

Specifically, a nozzle plate substrate 10 of suitable material (ceramic, glass or metal) may have an array of uniform holes 11 (e.g., 2 to 8 mil diameter) formed therein by known means, such as by E-beam or laser drilling or by etching.

A layer of glass 12 is then heated 13 and drawn into the hole 11 by capillary action. The glass fills in the walls of the hole 11 to form a nozzle 14 of significantly smaller diameter, which gives the resultant jet good directionality.
