High density reinforced orifice plate

摘要

A method for forming a high resolution reinforced polymer orifice plate with jet array for an ink jet begins by electroforming an array of cells onto a base forming a cell assembly. The base has a smooth reflective surface. The cell assembly is coated with a polymer forming a filled assembly. A photomask is applied to the filled assembly; the filled assembly is exposed to ultraviolet light; and the polymer is removed from the filled assembly forming a nozzle plate assembly. The nozzle plate assembly has nozzles respective to the array of cells electroformed onto the base. The nozzle plate assembly is heated and the base is removed from the nozzle plate assembly forming an orifice plate with a jet array. The orifice plate and the jet array are composed of the filled polymer forming a smooth surface.
