PURPOSE: A method for manufacturing a shield frame for shielding an electromagnetic wave is provided to form an orthogonally bent part by completely preventing a spring back phenomenon at the bent part. CONSTITUTION: A top mold(110) vertically moves toward a bottom mold(120). The top mold includes a top base plate(111), a combination plate(112), and an adhesion plate(113). The bottom mold includes a bottom base plate(122) and a work table(121) fixed to the upper side of the bottom base plate. A punch step(131) is formed on the side of a punch(130) toward a disk receiving unit(121a). A punch step unit applies pressure to an area near a pair of bent parts.
