ABSTRACT:
A method is disclosed for preparing orifice plates for ink jet printing apparatus from a set of orificed cylindrical jewels having substantially identical fluid flow rates therethrough. Several pairs of closely spaced thin wires are mounted transversely across a mold cavity. Each pair of wires is tensioned to support a cylindrical jewel without deflection. Two backing plates then are placed on the mold to position the jewels in precise alignment. The mold then is filled with a liquid resin to cover the jewels. The resin then is cured to a solid state. The cured structure is removed from the mold and the protruding wires are trimmed to form the finished orifice plate.
