Forming process when an ingot is heated in an induction coil to the semi-solid state and then pressed into a preheated mold. Beskrivning The process The method belongs to the semi-solid metal casting type. An ingot [1] with a non-dendritic structure must first be heated to a temperature between the metal liquidus and solidus. The heating is by induction heating and gives a 30-65% solid metal in which the primary phase has a globular structure to achieve a low viscosity that is necessary for the processing to occur. The ingot is then placed in a chamber [2], a plunger [3] presses the ingot into a preheated mold. The ingot then assumes the shape of the mold chamber and when the ingot is partially cooled, the pressure is taken away and the casting process is completed. Thixocasting Process films
