Abstract:
An improved hot runner system is provided. The hot runner system includes a hot drop having an inlet for receiving molten material, the inlet diverging into first and second channels that converge at a feeder tube for providing an even distribution of molten material in a mold cavity. The hot runner system further includes a valve pin adapted to reciprocate within the feeder tube for opening and closing the valve gate, the valve pin being moveable in response to activation of first and second linear actuators disposed exterior to the hot drop. The linear actuators are moveable in unison with each other and are joined to the valve pin via a cross-bar that extends through an interior portion of the hot drop between the first and second channels.
