The casting process begins with melting the metal. A crucible is placed in the casting machine, and metal blanks are placed in the crucible. The machine’s inductor is a hollow metal spiral that surrounds the crucible. When the machine is started, the inductor generates high-frequency electromagnetic oscillations.
These oscillations create chaotic movement of the metal molecules inside the crucible. As a result, the metal becomes particularly fluid, and its temperature rises significantly. The heating is localized, unlike a muffle furnace, as the machine’s elements do not become heated. The inductor is cooled by water flowing inside it.
The technician visually determines when the metal has reached a sufficient casting temperature. He places the preheated mold into its designated slot. Then, by moving a lever, the technician activates the rapid rotation of the machine’s structure holding the crucible and mold.
Under the influence of centrifugal force, the liquid metal moves to the side wall of the crucible and then into the mold. Once the metal penetrates deeply enough into the mold to fill the internal cavities, the rotation stops. After the casting process is complete, the mold is removed from the machine.
