A method and apparatus for injection molding a plastic part using a film gate. The film gate is constructed of a pair of tenon members which retract into a mortise tooled into a mold section. Because the tenon members extend to release the dross formed in the runner, the film gate may be placed in the center of the mold section to decrease the pressure gradient in the curing plastic and to allow the gate to be located where aesthetic aberrations, from the removal of the dross, will not be a problem in the finished article.
