  • Patent number: 4398083
    Abstract: An electric heating apparatus for softening and molding fillet wax strips used in foundry molds and castings includes a housing supporting a plurality of electric radiant heaters, such as lamps, above a platform for holding strips of fillet wax during preheating. An electronic control circuit is provided in the housing for varying the heat output of the radiant heaters and includes a thermostat located between the heater and the platform for limiting the temperature to prevent melting of the wax strips. Electrically heat fillet-forming tools, supported in holder on the housing during non-use periods, are provided for forming the preheated wax strips after application thereof to a mold. The tools are provided with ball-shaped tips and the housing is provided with a separate adjustable electronic control circuits for each tool so that the heat output of each tool can be adjusted to a temperature appropriate to the particular wax being worked and the size of the ball-shaped tip.
