A thick-film electric heater having thick-film layers applied directly on a thermally conductive non-flat substrate. Preferably, the substrate is cylindrically shaped. A dielectric layer is silk-screened on the substrate surface. A resistive layer is silk-screened on the dielectric layer to form a circuit for the generation of heat. The resistive layer has at least one resistive trace in a pattern that is discontinuous circumferentially. At least a pair of silk-screened contact pads are applied in electrical communication with the resistive layer for electrical connection to a power source. An insulation layer is applied over the resistive layer.

Thick film heater apparatus

An apparatus for heating a flowable material comprises a core having a passageway formed therein for the communication of the flowable material, and an electric element coiled in multiple turns against the core in a helical pattern. The electric element, in use, heats the core both resistively and inductively. The electric element has no auxiliary cooling capacity. The electric element may be installed against the outside of the core, with an optional ferromagnetic yoke installed over it, or it may be installed against the inside of the core, embedded in a wear-resistant liner. The yoke and liner may be metallic material deposited such as by hot-spray technology and finished smooth.

Apparatus for inductive and resistive heating of an object

An apparatus for retaining a heater on an injection molding nozzle comprises a retaining body configured to fit around the injection molding nozzle. The retaining body has two flanges extending inward. One is configured to be received in a groove in the injection molding nozzle; the other is configured to be received in a groove in the heater. An axial slot allows the retaining body to elastically spread outward. The retaining body also has at least one aperture that receives a thermocouple. The aperture is preferably an elongated hole having an axis parallel to a longitudinal axis of the retaining body. Preferably the heater is a thick-film heater and the thermocouple is installed adjacent one on the resistive elements of the thick-film heater. When the resistive elements produce different heat levels, the thermocouple is preferably installed adjacent the resistive element that produces the greatest heat.
