Abstract
A method for fabricating a liquid ink printhead orifice plate for use in a liquid ink printhead and printer. The liquid ink orifice plate is formed of a thermal plastic resin which is stamped between an orifice plate mandrel which includes the ink carrying features and a flat mandrel. Once the orifice plate has been stamped, excess material is removed from the orifice plate to reveal ink carrying features of the stamped orifice plate. The orifice plate mandrel is formed by electroforming a mandrel on an etched silicon wafer which defines a plurality of ink carrying channels and ink reservoirs. The electroform mandrel can be made of any number of metals which includes nickel.
