This invention relates generally to an apparatus for casting a portion of a tire or other article of manufacture, and, more specifically, to an apparatus that has a gate design, that has a plunging nozzle with a waste reservoir for separating off-ratio material before it enters the cavity that forms a portion of the tire or other article of manufacture. The design may further include a passage that connects the runner to the waste reservoir as-well as an air vent that allows trapped gas or air to exit the waste reservoir as it fills with waste material, a valve that is operative!'/associated with the passage for closing and opening the passage at appropriate times, and a nozzle constructed from two independently translating components for initially introducing material into the waste reservoir and subsequently into the runner.
