An electromagnetic forming apparatus for forming an essentially planar metal plate into a dish having a three-dimensional pattern, is provided. The apparatus comprises a mould having a forming surface with a contour corresponding to said three-dimensional pattern; a forming coil device; and an electric discharge circuitry for discharging a short and intense electric current pulse through the forming coil device to yield a pulsed magnetic forming (PMF) force for deforming said plate.
