Patent abstract
A method and apparatus for improving the quality of molded parts in a molding system having a valve stem and a valve gate. The valve stem is movable between a fully retracted position where the gate is fully open to a fully forward position where the gate is fully closed and into an intermediate position where the gate remains closed but the valve stem is displaced from the gate so heat transfer through the valve stem and into the gate region is minimized.
