Intended electric heating element because of technology

摘要

In order to create an electrical heating element for technical purposes, particularly for heating hot runner systems, hot runner distributors, hot runner nozzles, molds of injection molding machines, wherein a dielectric layer, onto which an electric resistance element comprising electrical connection contacts for the contact with an electric power source, is applied onto a surface of the heating element or of a heating element carrier, wherein the resistance element is covered by a protective layer, particularly a dielectric layer, said heating element being particularly easy, cost-effective and quick to produce in order to be able to supply high volumes at competitive prices, it is proposed to apply the resistance element by way of a functional printing process, wherein an emulsion or dispersion containing electrically conductive particles and a carrier or binding material is applied in drops onto the electric layer so as to form the electric resistance element.
