CA 2193157

An orifice plate is fabricated for use in an ink jet printer. Initially, a mandrel is provided, and a holder is aligned to the mandrel. The mandrel and the holder are maintained in intimate contact and at equal electrical potential. The mandrel and the holder are placed at cathodic polarity. A plating material is then applied to the combined mandrel and holder to cause the mandrel and holder to form a single orifice plate directly bonded to the holder. The mandrel is then removed from the orifice plate.

laque à orifice fabriquée pour utilisation dans une imprimante à jet d'encre. En premier lieu, un mandrin est fourni, et un support est aligné au mandrin. Le mandrin et le support sont maintenus en contact très étroit et à un potentiel électrique égal. Ils sont placés en polarité cathodique. Un matériau de plaquage est ensuite appliqué à la combinaison mandrin et support pour permettre à cette dernière de former une plaque à orifice unique directement liée au support. Le mandrin est alors retiré de la plaque à orifice.
