Method for producing a plastic vehicle part
A method for producing a plastic vehicle attachment part is described, wherein a polymeric film is laid in an injection mold, the polymeric film having an opaque or semi-opaque imprint or a color pigmentation. The polymeric film is back injected with a polymeric covering part, wherein the polymeric covering part is optically transparent. A polymeric carrier part is sprayed at least on a part of the surface of the polymeric covering part facing away from the polymeric film. A protective layer is applied at least on the polymeric film.
1. A method for producing a plastic vehicle attachment part comprising the steps of:
laying in an injection mold a polymeric film having an opaque or semi-opaque imprint or a color pigmentation,
back injecting the polymeric film with an optically transparent polymeric covering part,
spraying a polymeric carrier part on at least a part of a surface of the polymeric covering part that faces away from the polymeric film, and
applying a protective layer at least on the polymeric film.
2. The method according to claim 1 , wherein the protective layer is applied on all exposed surfaces of the plastic vehicle attachment part.
3. The method according to claim 1 , wherein the polymeric carrier part is opaque.
4. The method according to claim 1 , wherein the polymeric covering part is injection molded with a thickness from 1 mm to 10 mm.
5. The method according to claim 1 , wherein the polymeric carrier part is injection molded with a thickness from 0.5 mm to 10 mm.
6. The method according to claim 1 , wherein the polymeric covering part comprises polycarbonates (PC), polymethyl methacrylate (PMMA), styrene acrylonitrile (SAN), polyethylene terephthalate (PET), and/or copolymers or mixtures thereof.
7. The method according to claim 1 , wherein the polymeric carrier part comprises polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and/or copolymers or mixtures thereof.
8. The method according to claim 1 , wherein the protective layer comprises thermal-cured or UV-cured varnishes, and/or mixtures or copolymers thereof.
9. The method according to claim 1 , wherein the polymeric film contains polycarbonates (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate—polybutylene terephthalate (PBT/PC), styrene acrylonitrile (SAN), and/or copolymers or mixtures thereof.
10. The method according to claim 1 , wherein the polymeric film has a thickness from 0.1 mm to 3 mm.
11. The method according to claim 1 , wherein the polymeric film is pre-formed.
12. The method according to claim 1 , wherein the polymeric film extends over a region of 3% to 30% of an entire surface of the polymeric covering part.
13. The method according to claim 1 , wherein the polymeric film comprises a plurality of individual polymeric films, which respectively extend over a sub-region of the entire surface of the polymeric covering part.
14. A plastic vehicle attachment part comprising:
a polymeric film having an opaque or semi-opaque imprint or a color pigmentation, wherein the polymeric film is back injected with an optically transparent polymeric covering part,
an opaque polymeric carrier part sprayed at least onto a part of a surface of the optically transparent polymeric covering part, and
a protective layer applied at least on the polymeric film.
15. The plastic vehicle attachment part according to claim 14 , wherein the imprint contains organic pigments or inorganic pigments.
16. A method comprising:
using the plastic vehicle attachment part according to claim 14 as an exterior attachment part for a vehicle.
17. The method according to claim 4 , wherein the thickness is from 2 mm to 5 mm.
18. The method according to claim 5 , wherein the thickness is from 1 mm to 5 mm.
19. The method according to claim 1 , wherein the polymeric carrier part comprises acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene-polycarbonate (ABS/PC), PET/PC, PBT/PC, and/or copolymers or mixtures thereof.
20. The method according to claim 1 , wherein the protective layer contains polysiloxanes, polyacrylates, polymethacrylates, and/or mixtures or copolymers thereof.
