Abstract
A metallic overcoat is shown for use on the termination of a thick film heater. The invention is specifically useful for reducing overall wall thickness on thick film heaters used in the injection molding industry. The overcoat is placed over at least the termination point of the heating element with access holes for the termination. Thereafter, holes are drilled parallel to the heater axis for the insertion of power leads. The overcoat further provides insulation for better efficiency and mechanical protection for the heating element.
