ABSTRACT:
A die casting method and a die casting machine of the invention is provided. The method comprises the steps of forming a casting sleeve comprising an inner cylinder and an outer cylinder, having a conductor material, and disposing an induction coil on the outer periphery of the outer cylinder. The conductor material may be in the form of a plurality of conductors uncontinuously disposed about the cylinder or it may be in the form of a single conducting material having a plurality of slits. A material to be cast in the casting sleeve may be heated, maintained a constant temperature and stirred by electromagnetic induction. The material may be substantially separated from the wall face of the casting sleeve by an electromagnetic force generated between the conductor and the material and the temperature drop of the material may be suppressed. The material being casted can efficiently be heated, maintained a constant temperature and electromagnetically stirred, while maintaining the machine accuracy of the casting sleeve.
