Abstract:
1. A valve-gated injection molding system comprising: a nozzle body having an inlet, an outlet, and a melt channel extending from said inlet to said outlet, the melt channel having an end portion located adjacent to said outlet, the nozzle body having an offset body portion located between said inlet and said end portion and being laterally offset relative to a first axis; an actuator external to and positioned laterally to only one side of said offset body portion relative to said first axis, the actuator having a housing and a piston disposed entirely within the housing and slidable in the housing co-axially with said first axis; and a valve pin extending along said first axis, the valve pin being connected to the piston and having a tip portion positioned in said end portion and movable under the influence of the piston between a first position in which the tip portion does not stop the flow of melt through the melt channel in said end portion and a second position in which the tip portion stops the flow of melt though said end portion.
