| 摘要 | 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 circular runner and concentric channel or waste reservoir for separating off-ratio material before it enters the cavity that forms a portion of the fire or oilier 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 for initially introducing material into the waste reservoir and subsequently into runner. | ||||||
