A mobile phone includes a phone core with operative components thereof in a one piece phone housing that is directly molded to the phone core. Operative components that require exterior access from the housing, e.g., ear speaker, microphone, loudspeaker, SIM card reader, display, and keypad, may be shielded from molding material during the molding process by shielding boxes integrally molded into the housing and/or by shielding cores in the mold of a plastic injection molding machine. A plastic injection molding machine with shielding cores may form the phone housing as an integral structure directly to and about the phone core. A method of making a mobile phone includes plastic injection molding using insert molding technique.
