Abstract: A hot runner nozzle having an electrical heating element includes a connector for producing an electrical connection to a connection line, terminal contacts for the heating element terminating in an insulation body for the connector that separates the terminal contacts from one another electrically. The connection line has contact elements that are electrically contactable with the terminal contacts of the heating element. The insulation body is arranged at least in part in a receiving sleeve of the connector, that the connection line may be fixed in or on the receiving sleeve such that the contact elements of the connection line electrically contact the terminal contacts of the heating element, and that a first end of the receiving sleeve that faces towards the heating element wraps around the insulation body and has on this first end two opposing feet that face outward and that are attached to the heating element.

Abstract: An injection-molding equipment includes at least two cavities and at least one needle valve nozzle, each fitted with one needle, per cavity. The needles are displaceable by an electromagnetic drive into an open and a closed position to respectively release and close a gate aperture subtended in the particular related cavity. Each electromagnetic drive has at least one electromagnet with each sealing needle axially held in place in the open and in the closed position by at least one permanent magnet. A control unit generates individual power pulses of which the duration is defined and saved in said control unit. An electromagnet of an electromagnetic drive is fed a power pulse and generates an electromagnetic field to displace the sealing needle from its closed into its open position and vice-versa, with the power pulses for at least two electromagnetic drives being transmitted in time-staggered manner to the drives.
