A spray orifice particularly adapted for discharging a mixture of an atomized release agent entrained within a gas stream for coating a surface of a forming die. The orifice includes a body section having an internal cavity terminating in a ball-shaped cavity portion adjacent its outlet end. The outside surface of the body adjacent the outlet end has a shape complementary with the inside surface to provide a relatively uniform wall thickness. A laterally extending slot is cut into the end and has a maximum width at its center and tapers to a minimum width at its lateral ends. Such configuration reduces the likelihood of finely atomized liquids dispersed in the pressurized gas stream from recombining to form larger size droplets. The included angle of discharge from the slot is adjustable through a rotatable adjustment cap having diametrically opposite cam surfaces which selectively cover side portions of the slot. A lock nut is used to maintain the adjustment cap in a desired set position.
