Abstract
A single or multi-orifice metal nozzle structure suitable for use in an ink jet printing system. The metallic nozzle member has at least one orifice extending therethrough, the orifice including a cylindrical portion, adjacent the outlet face of said nozzle, having a height ranging from 0.25 to 5 times its diameter and at least one frustoconical section divergent toward the face opposite the outlet face and communicating with the cylindrical portion. Where the metal nozzle is a multi-orifice metal nozzle, each frustoconical section communicates with a groove disposed in the face opposite the outlet face. The multi-orifice metal nozzle is prepared by grooving a metal plate with at least one groove, punching a plurality of frustoconical sections into the groove member and then forming a cylindrical portion into each frustoconical section and through the plate member.
