Abstract:
A method for injection molding articles, which comprises the steps of:feeding at least one molten material from an injection nozzle via at least one nozzle outlet to a mold cavity space of an injection mold through a mold gate substantially in line with said at least one nozzle outlet; and eliminating waste of said molten material during molding by positioning a thin, movable valve gating means with an orifice therein between the mold gate and said at least one nozzle outlet, and moving said valve gating means between a first position wherein said orifice communicates with said at least one nozzle outlet and mold gate and permits the flow of molten material from said at least one outlet to said mold gate, and a second position blocking flow from said at least one nozzle outlet to said mold gate without said molten material being transferred by said thin, valve gating means, during movement of said valve gating means between said first and second positions.
