Abstract: A housing for an electronic device includes a metal member combined with a plastic member. The combination molds the metal member to the plastic member but the plastic member is discontinuous and recesses and protrusions are cut into the metal member to enable molding and bonding with the plastic member in the manner of a dovetail joint.

The metal member and the plastic member are thus integrally formed and a thickness of a recess is less than a thickness of the plastic member. An electronic device and a method for making the housing are also provided.
