The electrical heating for a cylindrical body, e.g. plastics injection jets and the like, has a tube heating body (1) around the cylindrical component, with its heating conductor embedded in a highly compressed magnesium oxide core within a metal mantle. The heating tube is in a serpentine or coil layout. The heating tube is pressed into the cylindrical inner surface of the body (5) with its complete cross section. |
