ABSTRACT:
A hot plate with a base and a heater plate, both the heater plate and the base being hollow and filled with an expanded and voluminously enlarged foam epoxy encapsulating the lead and power wires and pressing the electric resistance heater ribbon firmly against the ceramic top deck and extruding around the closure plate to seal and secure the entire heating plate and base in single unitary units. The method disclosed includes the pouring of the foaming epoxy system wherein the epoxy expands and creates a pressure within the cavities or chambers of the hot plate and urges the resistance heater firmly against and in intimate engagement with the top deck of the ceramic panel by reason of the growth of the foaming epoxy which seals and insulates against heat migration.
