A single-nozzle pneumatic valve gate for “zero-vestige” cosmetic surfaces is retrofittable to existing molds. The MS75SNVG nozzle from Polyshot Inc., West Henrietta, N.Y., has an internal piston assembly so no additional thickness is required on the top clamp plate of the mold. Like Polyshot’s manifold-mounted valve gates, it has a cylindrical rather than tapered valve pin. No O-rings are needed on the piston. The nozzle fits within a 4-in. diam. locating ring.
