Abstract
The present technique provides a system and method for improving atomization in a spray coating device. An exemplary spray coating device of the present technique has a fine finish tip with an atomization section comprising a first fluid impingement orifice, i.e., a pre-orifice, angled toward an expansion chamber and a subsequent second fluid impingement orifice. The fine finish tip is provided as a unitary assembly that may be applied to a spray gun and that provides a fixed relationship between the pre-orifice, the expansion chamber, and the second orifice, which results in refined spray characteristics, such as uniform particle distribution and uniform fan pattern shapes.
