The effects of some factors such as the thickness of mold wall, the resistivity of mold upside part, electrical frequency and coil current intensity to the penetration of magnetic field in two-stage mold were investigated. The magnetic flux density is decreased with the electrical frequency and thickness of mold increasing, but increased with the resistivity of upside mold and coil current intensity increasing. The order of factors affecting the penetration of magnetic field in two-stage mold is electrical frequency＞mold upside resistivity＞coil current intensity＞mold wall thickness. By dimensionless analysis, the relation equation between magnetic flux density and four parameters was given: B/(μ0I/d)= 4.36×109(ρ/If)0.89. Finally, the perfect parameters of two-stage mold used in EMCC are obtained: the thickness of mold wall is 5 mm，the resistivity of mold upside part is 8.8×10-7 Ω•m，coil current intensity is 2000 A, the supply frequency is above 2000 Hz.
