Traditional methods of decorating injection molded parts have included painting, screen printing, pad printing, and hot stamping. These methods are all postmolding operations that require additional processing steps and environmental controls. In recent years alternate decoration methods have been developed. These decorating methods include in-mold foils, insert molding using polycarbonate film, and sublimation heat transfers. Bayer has developed materials and processes for insert molding polycarbonate-based films. This includes the development of water-based inks, forming methods and equipment for registering films in the mold, and most recently a high-heat polycarbonate printing. These materials and processes are designed to provide increased design flexibility, recycling, and lower total cost than traditional decoration methods.
