ABSTRACT:
A casting method and an apparatus therefor are disclosed, in which a molten material in a retaining furnace is poured through a supplying conduit directly into a cavity of a mold at a low pressure. A portion of the conduit is provided with an electromagnetic induction pump while the furnace is provided movably therein with a level-detecting sensor for detecting a level of the molten material in the furnace and generating a signal which provides instructions of computing, commanding and controlling an excitation voltage of the electromagnetic induction pump, thereby to optimize the injection pressure and the amount of the molten material in the conduit when the molten material is poured into the cavity of the mold through the conduit.
