Abstract:
An apparatus to be used in conjunction with an injection molding machine, the apparatus comprising:a cavity plate;a core plate disposed relative to the cavity plate so that the core plate and cavity plate together form a cavity space;a manifold having formed therein an inlet passage for receiving a flow of molten resin from a nozzle of the injection molding machine;a hot runner nozzle for directing the flow of molten resin from the manifold inlet passage to the cavity space;a mold gate for regulating the flow of molten resin from the hot runner nozzle to the cavity space, the mold gate together with the hot runner nozzle and the manifold inlet passage defining a melt channel for directing the flow of molten resin from the nozzle of the injection molding machine to the cavity space; andan active or passive thin film element directly deposited on a flexible substrate which is disposed along an inside of the melt channel upstream of the cavity space so as to contact the molten resin inside the channel.
