Abstract
A method for taking a nozzle of a valve gated runner apparatus includes releasably attaching a valve pin to a movable part of an actuator for moving the valve pin between an open position and a closed position and detaching the valve pin from the actuator by moving the movable part of the actuator towards the open position when the valve pin is immobilized. The valve pin and the movable part valve pin may be releasably attached by a magnetic force. The step of detaching the valve pin from the actuator may be accomplished by overcoming the magnetic force. A valve pin plate can be provided for a plurality of valve pins to be releasably attached to the actuator.
