Abstract

A method of fabricating a plastic part having a three-dimensional image and visual effect. A plastic part having a three-dimensional graphical surface and a flat plane is formed. Subsequently, a thin film layer is formed on the plastic part to provide three-dimensional image and visual effect to the plastic part, where the three-dimensional graphical surface provides the three-dimensional image and the thin film layer provides the visual effect.

Claims

1. A method of fabricating a plastic part having a three-dimensional image and visual effect, comprising:

fabricating a plastic part, the plastic part having a three-dimensional graphical surface and a flat plane; and

forming a thin film layer on the plastic part so that the plastic part has a three-dimensional image and a visual effect, the three-dimensional graphical surface of the plastic part providing the three-dimensional image, and the thin film layer providing the visual effect.

2. The method of claim 1, wherein the thin film layer is disposed on the three-dimensional graphical surface of the plastic part.

3. The method of claim 2, wherein the thin film layer is a thin metal film layer.

4. The method of claim 3, wherein the thin metal film the layer is fabricated by means of a physical vapor deposition process or a chemical vapor deposition process.

5. The method of claim 1, wherein the thin film layer is disposed on the flat plane of the plastic part.

6. The method of claim 5, wherein the thin film layer is a plastic thin film.

7. The method of claim 5, wherein the thin film layer is formed on the flat plane of the plastic part by means of attachment.

8. The method of claim 6, further comprising a step of forming an information layer on a surface of the thin film layer or on the flat plane of the plastic part, before the step of forming the thin film layer of the plastic part.

9. The method of claim 8, wherein the information layer is formed by means of a printing process or a plating process.

10. The method of claim 1, wherein the step of fabricating the plastic part comprises:

performing a Lithographie Ga Vanoformung Abformung like (LIGA-like) process to form a stamper, the stamper having a three-dimensional graphical surface that is complementary to the three-dimensional graphical surface of the plastic part; and

performing an injection molding process by utilizing the stamper, so as to fabricate the plastic part having the three-dimensional graphical surface.

11. The method of claim 1, wherein the plastic part is fabricated by means of a thermal compression process or a cold compression process.

12. The method of claim 1, wherein the plastic part is fabricated by means of a casting process.

13. The method of claim 1, wherein the plastic part is fabricated by means of a calendaring process.

14. A method of fabricating plastic thin film having three-dimensional image, comprising:

performing a Lithographie Ga Vanoformung Abformung like (LIGA-like) process to form a stamper; and

performing an injection molding process by utilizing the stamper, so as to fabricate a plastic thin film having a three-dimensional graphical surface.

15. A plastic part having a three-dimensional image and visual effect, comprising:

a plastic part, the plastic part having a three-dimensional graphical surface; and

a thin film layer, covering the three-dimensional graphical surface of the plastic part, thickness of the thin film layer being approximately uniform, the thin film layer rising and falling according to an outline of the three-dimensional graphical surface, the three-dimensional graphical surface providing the three-dimensional image, and the thin film layer providing the visual effect.

16. The plastic part of claim 15, wherein the thin film layer is a thin metal film layer.

17. A plastic part having three-dimensional image and visual effect, comprising:

a plastic part, the plastic part having a three-dimensional graphical surface and a flat plane; and

a thin film layer, covering the flat plane of plastic part;

wherein the three-dimensional graphical surface provides a three-dimensional image, and the thin film layer provides a visual effect.
