An electronic casing and a method of manufacturing the same are provided. The method includes the following steps. Step (a): a metal laminate and a die of a predetermined shape are provided. The metal laminate comprises a metal top layer and a metal bottom layer that are bonded by interface atom diffusion. Step (b): the metal laminate is processed to form a casing blank by using the die, and the casing blank has at least one turning portion. Step (c): a profiler of a predetermined shape and an electromagnetic forming device are provided. Step (d): the casing blank is attached to the profiler, and the electromagnetic forming device is disposed at a position corresponding to the turning portion. Step (e): the electromagnetic forming device is activated, so that the casing blank has a shape corresponding to the predetermined shape of the profiler.

An electromagnetic forming device for a sheet of material is provided. The electromagnetic forming device includes a fixing base, a magnetic concentration block, an electromagnetic actuator, and a die. The fixing base has a groove. The magnetic concentration block is disposed in the groove of the fixing base, and has an accommodating space therein, which is in communication with a surface of the magnetic concentration block via a slit. The electromagnetic actuator, used to generate a magnetic field, is disposed in the accommodating space of the magnetic concentration block, but does not contact the magnetic concentration block. The die and the magnetic concentration block are separated by a gap, and a sheet of material can be disposed in the gap. As the magnetic concentration block is a block, eddy currents in the magnetic concentration block are distributed uniformly, so the generated magnetic field is also distributed uniformly, thus exerting a uniform forming force on the sheet of material.
