ABSTRACT:
Tubular needles have a reduced inner diameter tip portion that increases back pressure behind the tip portion. This constricted tip portion promotes improved atomization, particularly when the liquid passes through the needle at near-supercritical conditions. A preferred method for constricting the inner diameter of a needle tip is to dip the dip of the needle in an electroless plating solution, such as an electroless nickel solution.
