The Electromagnetic Confinement and Shaping (EMCS) process is a crucibleless melting and mouldless shaping technology by alternating magnetic field. In this paper, stability of the shaping, effect factors of the electromagnetic force and the temperature field and the procedure of the EMCS process are systemically analyzed. The Results indicate that a good coupling of the temperature field and the electromagnetic force is important to stably shape for liquid metal, and the gravity force of liquid metal is more sensitive to change of the temperature (or the current through the inductor) than the electromagnetic force does above the melting point of the sample. Several stainless steel samples were obtained by EMCS process.
