Abstract
An injection molding apparatus includes a manifold for delivering a melt stream of moldable material to a nozzle melt channel of a nozzle. A valve pin extends through the nozzle melt channel and is axially movable to selectively open a gate to allow communication with a mold cavity. A sensor is coupled to a forward end of the valve pin. The sensor may be a pressure sensor and/or temperature sensor in direct contact with the melt stream to provide pressure and/or temperature information to a controller.
