  • Apparatus for momentarily heating the surface of a mold
    Patent number: 6638048
    Abstract: Disclosed herein is a system for momentarily heating the surface of a mold and system thereof. The system comprises a casting material feeder, upper and lower molds, an injection molding control, an air and gaseous fuel mixture and supply unit, an interface and a control panel. The casting material feeder serves to supply molten casting material. The upper and lower molds serve to form a predetermined shaped cast. The injection molding control serves to control the upper mold and the lower mold. The air and gaseous fuel mixture and supply, unit serves to supply compressed air and gaseous fuel simultaneously or selectively. The gaseous fuel mixture and supply control serves to control the operation of the air and gaseous fuel mixture and supply unit. The interface serves to interface the injection molding control and the gaseous fuel mixture and supply control. The control panel serves to visually display the control, condition and operation of the components of the system.
