PURPOSE: A low-pressure casting machine is provided to prevent burn of an operator by reducing the radiation of heat and minimizing heat loss. CONSTITUTION: A low-pressure casting machine comprises a mold(30), a bottom-supporting plate(20), a warming furnace(10), four fixing posts, an upper support plate, a mounting bracket, a drive motor for high speed input, a drive motor for high load input, a drive unit, four lifting rods, a ball screw shaft, a ball screw shaft support unit, and a horizontal moving unit. The warming furnace comprises a container(11), a first insulation layer(12), a second insulation layer(13), a first iron casing(14), an outer sectional layer(15), and a second iron casing(16). A heating source is installed inside the container. The first insulation layer covers the surface of the container. The second insulation layer covers the surface of the first insulation layer. The first iron casing covers the surface of the second insulation layer.
