Abstract (en)
[origin: WO2005079115A1] The invention relates to an electric heating body in the form of a compressed heating element which heats the cylindrical component on the exterior thereof, preferably, in the form of a spiral-tube element, on the injection nozzle of injection moulding or die casting tools or similar heatable cylindrical components. Said electric heating body consists of a metallic cover wherein an MgO- ceramic is arranged and a heat conductor spiral is embedded therein. The material of the metallic cover has a tensile strength Rm at 500 DEG C of > 650 N/mm<2> and a yield strength Rp0,2 at 500 DEG C which is approximately the same size, in order to obtain a permanent radial contact pressure of the spiral-tube element on the component which is to be heated based on the spring properties thereof.
