Abstract
A method and apparatus for ensuring consistency of color and cosmetic appearance of injection molded parts used in the fabrication of enclosures for information handling systems. A sample of polymer material having a texture and color in accordance with a predetermined specification is inspected by a spectrophotometer and the results of the measurements are stored in a cosmetic feature database of a manufacturing system. A plurality of enclosures for the information handling systems are then manufactured using information stored in the cosmetic feature database. Each of the enclosures has a molded feature that can be used to verify surface finish quality and color consistency of the injection molded parts used to fabricate the enclosure. In a production run for fabricating a plurality of enclosures, one of the enclosures can be removed from the production line and a molded feature can be inspected to determine whether the molded parts comply with predetermined standards for color and surface finish.
