Definitions
- the present invention relates to a method for producing a component having at least two color layers for a motor vehicle, wherein the
- Color layers on a thin-walled, the geometry of the component at least partially defining support structure are applied, wherein the support structure consists of a transparent or translucent polymer material, wherein the support structure has a visible in the intended use outside and the outside opposite the back, wherein the at least two color layers be applied to the back of the support structure and as a result visible through the support structure on the outside at least partially visible or recognizable, wherein the support structure has a first region or first areas in which recognizable on the outside only a first color layer or only parts of a first color layer are, and wherein the support structure further comprises a second region or second regions in which on the outside only the at least one further color layer or only parts of the at least one white Teren color layer are recognizable.
- Umformungs- or deformation process a precise, and in particular
- a complex structure eg a color grid or parallel lines
- a masking template is therefore deposited on the carrier structure for application of the first color layer and then with a

- the use of an injection molding process for the coating and simultaneous masking of the first region makes it possible, in comparison with prior art processes, to apply a very precise masking with a high spatial resolution also on an already three-dimensionally preformed support structure.
- the back of the support structure of the component is also called "second-surface" or B-side.
- the support structure preferably has a three-dimensionally formed geometry with at least one space curvature, particularly preferably with at least two space curvatures.
- the application of the at least one further color layer to the second region or to the second regions on the rear side of the carrier structure can be effected by means of a coating process which differs from the injection molding process. Due to the fact that the first color layer applied by means of the injection molding process already forms the masking on the carrier structure, a coating method can be selected for the at least one further color layer, which is larger in comparison to the injection molding method
- Area performance ie painted area per time
- Area performance has. By combining the very precise injection molding process with a coating process with larger area performance, a process with high accuracy and high speed can be realized.
- the deviating coating method may include a spray painting method or a spray painting method or a paint coating or a dip painting or a roller painting or a plating method, in particular a PVD method or a CVD method, or a plating method.
- the curing and / or solidification of the first color layer can be accelerated at least partially by active cooling.
- the first color layer preferably has a layer thickness in the range of 0.1 mm to 5 mm.
- the first color layer may comprise at least one functional element projecting from the first color layer, which is formed integrally with the first color layer and together with the first color layer.
- the functional element becomes Consequently, at the same time produced together with the first ink layer by injection molding in the same injection molding tool.
- the at least one functional element can in particular be a connecting element for connecting the component to a further component.
- Connecting element can be an example of a part of a latching connection
- the functional element can also be a ribbing that stiffens the component.
- the second region or regions may or may be predetermined by local surface irregularity or by local surface irregularities on the outside and / or on the backside of the support structure.
- This surface irregularity or these surface irregularities can then additionally be visually emphasized by means of the at least one further color layer.
- the at least one further color layer exactly on the surface irregularity or surface irregularities
- the local surface irregularity may be formed by a depression or a bead or a groove or a lettering sunk in the material of the support structure or a satin finish or a raised pattern and / or a sunk in the material of the support structure pattern, or the local Surface irregularities may be due to beading and / or grooves and / or in the material of the support structure sunken lettering and / or satin and / or grain and / or raised pattern and / or in the material of
- Carrier structure submerged pattern be formed.
- manufacture or provision of the support structure can be carried out by means of a generative process (for example 3D printing) or by injection molding or by means of an injection molding process
- Thermoforming done In the case of production by injection molding, the production can be carried out in the same injection molding tool used to apply the first color coat. In this case one speaks of one
- the first color layer and / or the at least one further color layer may be built up or built up by a multiplicity of individual layers. That is, the first color layer and / or the at least one further color layer can in particular be composed of at least two or more individual layers.
- the at least one further color layer can be formed by a metal coating, in particular by a chromium coating. Consequently, the at least one further color layer does not necessarily mean a lacquer layer, but may also be a coating by a metal.
- a transparent or translucent protective lacquer layer can be applied.
- the component may be an exterior component of a motor vehicle, in particular a bumper cover or a radiator grille trim or a
- the component may be a component of an exterior component of a motor vehicle, in particular a component of a bumper cover or grille trim or fender trim or A-, B-, C- or D-pillar trim or spoiler skin or sill trim or door outer trim or door trim outer trim form.
- the transparent or translucent polymer material of the support structure may in particular comprise polycarbonate, polymethylmethacrylate, polystyrene (for example PS, ABS, ASA), thermoplastic polyester (for example PET, PBT) or a biopolymer (for example cellulose acetate, polyhydroxybutyrate, polylactic acid, polyhydroxyalkanoate).
- polycarbonate polymethylmethacrylate
- polystyrene for example PS, ABS, ASA
- thermoplastic polyester for example PET, PBT
- a biopolymer for example cellulose acetate, polyhydroxybutyrate, polylactic acid, polyhydroxyalkanoate
- Fig. 1 cross-sectional view of the support structure after the application of the first color layer and the at least one further color layer.
- FIG. 1 shows a component comprising at least two color layers 1, 2 for a motor vehicle, the color layers 1, 2 being applied to a thin-walled carrier structure 3 which at least partially defines the geometry of the component.

- the claimed method for producing a component having at least two color layers 1, 2 for a motor vehicle has the following sequence of steps:
- the application of the at least one further color layer 2 to the second region 8 or to the second regions 8 the back B of the support structure 3 is effected by means of a different from the injection molding process coating method.
- the differing coating method comprises a spray painting process or a spray painting process or a paint coating or a dip coating or a roller painting or a plating process, in particular a PVD process or a CVD process, or a galvanic deposition process.
- the carrier structure 3 already has a three-dimensionally formed geometry with at least one space curvature before the application of the first color layer 1.
