  • Patent number: 7359144
    Abstract: In general, the invention is directed to techniques for forming a seal between parts of an overmold component. The overmold component includes a first part forming one or more thorough-holes and a second part overmolded to the first part. A through-hole may be, for example, a screw hole or an overmold material entrance hole. The through-holes formed by the first part are surrounded by an adhesive prior to overmolding the second part. After overmolding, the adhesive locally bonds the surface of the first part to the overmold part to make a seal around the through holes. For example, the overmold component may combine with a cover to form a housing of a disc drive or other electronic device defining an internal environment. In this example, the adhesive prevents external contaminants from entering the internal environment via the through-holes.
