BFN 6828 MOLDED ORIFICE PLATE ASSEMBLY FOR AN INK JET RECORDER AND METHOD OF MANUFACTURE Abstract of the Disclosure An orifice plate (10) for use in an ink jet recorder is integrally cast with an orifice plate holder (12), The orifice plate is formed having a flat, tapered bottom portion containing at least one row of orifices and has sidewalls extending outwardly from the bottom portion at acute angles from horizontal. The orifice plate holder (12) is formed from a castable plastic material which serves as a damping material. The holder is cast over and around the sidewalls (11) of the orifice plate to define, with the bottom portion of the orifice plate, a portion of an ink supply manifold. The damping action of the holder isolates the orifice plate (10) from spurious vibrations which could adversely affect the quality of printing from the ink jet recorder. Only the desired vibration from the stimulation transducer reaches the orifice plate. The mass and rigidity of the holder confines the traveling wave induced by the transducer to the orifice plate.
