Abstract: This invention provides a method for manufacturing decorated-parts of high design-quality and reliability, since the exposed surface of the base coat-layer is not bulged, and thus the color of said coat-layer is distinct. The method for manufacturing decorated-parts of this invention comprises a base coat-layer-forming process, a surface coat-layer-forming process and a laser-decorating process. In the base coat-layer-forming process, a resin-base material of a highly light color at a lightness-level of 70 or more or a clear and colorless resin base-material is formed. In the surface coat-layer forming process, the surface coat-layer of a less-bright color at a lightness-level of 20 or less is formed on the base coat-layer. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.

Abstract: A method for manufacturing a decorated-part comprises a first and second base coat-layer-forming process, a surface coat-layer-forming process and a laser-decorating process. In the first base coat-layer-forming process, the first base coat-layer colored in a highly light color at a lightness-level of 70 or more is formed on the surface of the resin base-material 12. In the second base coat-layer-forming process, the second base coat-layer 21C colored in a chromatic color is formed on the first base coat-layer. In the surface coat-layer-forming process, the surface coat-layer colored in a less-bright color at a lightness-level of 20 or less is formed on the second base coat-layer 21C. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the second base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.

Abstract: This invention provides a decorating device for vehicle-interior components, which can accurately provide gradation on the design of the surface of a resin component. The decorating device comprises a laser-irradiating device and a control device. The control device comprises a virtual-decorating surface 5a that is deformed so as to have a different curvature than the surface of the actual decorating surface 5, thus allowing for the drawing of designs thereon. The control device prepares laser-irradiating data based on the drawing-data, and it controls the laser-irradiating device based on the laser-irradiating data. The laser-irradiating device irradiates the laser L1 focused on the virtual-decorating surface 5a and conducts the laser processing on the actual decorating surface 5, with the focal point of the laser L1 having been shifted from the actual decorating surface 5.
