A device producing a patterned plate includes a die and an electromagnetic actuator. The die includes a patterned surface with a pattern formed thereon and a fracturing part. The tubular work piece is disposed between the die and the electromagnetic actuator such that walls of the tubular work piece correspond to walls of the die. When the electromagnetic actuator is supplied with a current pulse, an eddy current is induced in the tubular work piece, generating a repulsive force between the electromagnetic actuator and the tubular work piece. Therefore, the tubular work piece impacts the die, and a forming surface of the tubular work piece is deformed against the patterned surface and the fracturing part, thus replicating the pattern of the patterned surface onto the forming surface. At the same time, the tubular work piece is fractured at the position corresponding to the fracturing part. |
