Abstract
An injection molding apparatus includes an inlet component, a plurality of nozzles, and a plurality of hoses, each of which is not heated. The hoses are connected between outlets of the inlet component and respective molding material inlets of the nozzles for conveying molding material from the inlet component to the nozzles. Hoses may also be connected between a rail plate and the nozzles for delivering cooling fluid or actuation fluid for an actuator to and from the nozzles. The nozzles may be fastened to a mold plate of the injection molding apparatus, such as by a threaded bushing. A heated insert may at least partially define the mold cavity to heat molding material in the mold cavity.
