Abstract

This invention broadly relates to the construction of cylindrical ohmic heating elements. In particular, this invention relates to the use of cylindrical ohmic heating elements to heat the nozzle of an injection mold hot runner. The proposed heater is to be made by weaving an insulated resistive element (made of NICHROME, or similar) wire in a cylindrical shape. (Sleeve) Woven tubes will be made from suitable resistance wire inter-woven with high temperature ceramic composites. An inherent characteristic of the woven tubular element is that it does not require any clamping means to hold it in place.
