ABSTRACT:
A nozzle tip especially useful with airless sprayers is formed from a plurality of parts, all of which are fabricated from blanks of hard, wear-resistant materials such as ceramics or powdered metals. Exterior surface portions of the nozzle tip parts are final-formed during formation of the blanks, typically during a sintering operation. Mating interior surface portions of the nozzle tip parts, as well as a nozzle orifice portions, are formed quickly and inexpensively by machining. Principles of the invention are also applicable to spray nozzles of the electrostatic type. A thin, electrically conductive blade may be clamped between or among adjacent nozzle tip parts with a portion of the blade extending forwardly of the nozzle tip parts to charge liquid particles being sprayed.
