Abstract
A method of making a thermally-conductive casing for an optical head in a disc player is provided. The method involves molding a polymer composition comprising: i) about 20% to about 80% by weight of a polymer matrix such as polyphenylene sulfide, and ii) about 20% to about 80% by weight of a thermally-conductive material such as carbon graphite into a casing for the optical head. A reinforcing material, such as glass, and other additives, such as flame retardants, can be incorporated into the polymer composition.
