Abstract
A device for producing a pattern onto a work piece includes a die, an electromagnetic actuator and a base. The die includes a patterned surface, and the patterned surface includes a pattern. The electromagnetic actuator includes an plate body, a convex part and a strip unit connected to the plate body. The electromagnetic actuator is disposed in the base. When the electromagnetic actuator is activated while a work piece is being positioned between the patterned surface and the electromagnetic actuator, an inductive current is generated on the work piece by the electromagnetic actuator, and then a repulsive force is generated between the electromagnetic actuator and the work piece. The repulsive force causes the work piece to adhere to the patterned surface, forcing the work piece to deform against the patterned surface and to take on the shape of the pattern.
