    • A die-casting method capable of solving problems such as air entrainment and misruns during injection into a die cavity so that defect-free good castings can be efficiently produced, and castings obtained by such a die-casting method. The method comprises flowing molten metal into a casting sleeve (2) from a molten metal supply unit via a mouthpiece (7) and a molten metal supply opening (4) until the molten metal reaches a predetermined level and thereafter a plunger chip (5) rises in the casting sleeve (2) and stops in a position where its side blocks the molten metal supply opening (4). The molten metal thus flowed into the casting sleeve (2) is cooled by a cooling medium in a passage (2b) bored in the casting sleeve (2), and forms primary crystals, which are then time being electromagnetically stirred by a high-frequency coil (6) to be fluidized and soaked. At this moment, the temperature of the molten metal is detected by a sensor and, when the solidus rate is considered to have reached any desired value between 10 and 60 %, the plunger chip (5) is raised to pour the molten metal in a half-solidified state into a die cavity (1).

The casting material, which can be liquid metal, semi-solid metal or metal-matrix composite, in the shot chamber (12) of a die-casting machine (10), is driven to flow with high shear rate to mix homogeneously by the electromotive force induced with at least one low-frequency shifting electromagnetic field. The temperature and the microstructure of the casting material near the shot chamber (12) are further controlled and perturbed by at least one high-frequency electromagnetic field to minimize the temperature difference or the growth of dendritic microstructure. To ensure the efficiency of the electromagnetic fields, the shot chamber (12) is made of non-magnetic material and its wall thickness is less than three times the penetration depth of the electromagnetic fields. The shot chamber (12) is surrounded by at least one solenoid coil (24), a conducting shield (26), and at least one electric motor stator (20). The conducting shield (26), which only allows the low-frequency electromagnetic field to penetrate, protects the stator (20) from being overheated by the high-frequency electromagnetic field.
