A method of manufacturing a driving drum includes: molding a first cylindrical member including first large- and small-diameter parts, a diameter of an outer circumferential surface of the first small-diameter part being smaller than that of the first large-diameter part; molding a second cylindrical member having second large- and small-diameter parts, a diameter of an inner circumferential surface of the second large-diameter part corresponding to the diameter of the outer circumferential surface of the first small-diameter part, a diameter of an inner circumferential surface of the second small-diameter part corresponding to that of the first small-diameter part, and the diameter of the inner circumferential surface of the second small-diameter part being smaller than that of the second large-diameter part; and forming a first cam groove between the first and second small-diameter parts and forming a second cam groove between the first and second large-diameter parts.

A punching device for punching a workpiece includes a punching part and a broaching part. The punching part has a punching cutting edge that limits a punching cutting area, the punching part being intended to pierce the workpiece. The broaching part is intended to tear the workpiece later than the punching part, and includes at least a broaching tooth with a cutting edge that limits a cutting area which is greater than the punching cutting area.

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.
