ABSTRACT:
Apparatus for coating one surface of a molded article that consists of a pair of relatively movable die members which when closed form a cavity for molding the article in a desired configuration. One of the die members has a chamber formed therein into which a predetermined amount of liquid coating material is supplied through an injector device which is selectively movable into and out of engagement with an inlet port formed in the die member that communicates with the chamber. After the chamber is charged with the coating material, a plunger forces the material into the cavity to coat the outer surface of the article while the die members are closed.
