Abstract

An injection-molded product having a multilayer pattern, includes: a main layer formed on the injection-molded product, the main layer either protruding from or being recessed on a surface of the injection-molded layer, thereby forming a base pattern; a dual-level layer formed on the main layer, the dual-layer either protruding from or being recessed on the main layer, thereby providing a cubic effect and a gripping sense for the main layer; a deposition layer deposited on the surface of the injection-molded product so as to implement a color sense for the injection-molded product; and a clear coating applied to the deposition layer so as to protect the surface of the injection-molded product and the deposition layer

Claims

1. An injection-molded product having a multilayer pattern, comprising:

a main layer formed on the injection-molded product, the main layer either protruding from or being recessed on a surface of the injection-molded layer to form a base pattern;

a dual-level layer formed on the main layer, the dual-layer including at least one layer part either protruding from or being recessed on the main layer to provide a cubic effect and a gripping sense for the main layer;

a deposition layer deposited on the surface of the injection-molded product so as to implement a color sense for the injection-molded product; and

a clear coating applied to the deposition layer so as to protect the surface of the injection-molded product and the deposition layer.

2. The injection-molded product as claimed in claim 1, wherein the main layer is formed on the surface of the injection-molded surface using at least one of NC discharge, etching, laser, and sand paper.

3. The injection-molded product as claimed in claim 1, wherein the dual-level layer is formed on the top of the main layer using at least one of NC discharge, etching, laser, and sand paper.

4. The injection-molded product as claimed in claim 1, wherein the dual-level layer comprises:

a protrusion layer part including one or more protrusions protruding from the main layer; and

a recess layer part including one or more recesses recessed in different depths on the main layer.

5. The injection-molded product as claimed in claim 1, wherein the deposition layer is formed by a metal film which is formed by depositing a metal material containing at least one of tin, silicon, titanium, aluminum, chrome, and stainless steel, and wherein the metal film is deposited at a thickness in the range of 0.01 to 0.1 μ

m on the surface of the injection-molded product.

6. The injection-molded product as claimed in claim 1, wherein the clear coating is coated at a thickness in the range of 15 to 20 μ

m.

7. The injection-molded product as claimed in claim 1, wherein a base coating is coated at a thickness in the range of 5 to 15 μ

m between the deposition layer and the clear coating, the base coating increasing the luminescence of the deposition layer and providing a color sense for the deposition layer.

8. The injection-molded product as claimed in claim 1, wherein the surface of the injection-molded product is pre-processed prior to depositing the deposition layer, thereby providing a pre-processed surface part, and wherein one of nitrogen gas, oxygen gas and argon gas is used for pre-processing the surface of the injection-molded product.

9. The injection-molded product as claimed in claim 8, wherein a base coating is coated at a thickness in the range of 5 to 15 μ

m between the deposition layer and the clear coating, the base coating increasing the luminescence of the deposition layer and providing a color sense for the deposition layer.

10. A method for fabricating an injection-molded product having a multilayer pattern, comprising:

forming a main layer and a dual-level layer, the main layer either protruding from or being recessed on a surface of the injection-molded layer to form a base pattern, and the dual-level layer being formed on the top of the main layer in such a manner that the dual-level layer includes at least one layer part either protruding from or is recessed on the main layer, thereby providing a cubic effect and a gripping sense for the main layer;

forming a deposition layer by depositing a metal material on the surface of the injection-molded product; and

applying a clear coating to the top of the deposition layer, the clear coating being adapted to protect the surface of the injection-molded product and the deposition layer.

11. The method as claimed in claim 10, wherein the main layer is formed on the surface of the injection-molded surface using at least one of NC discharge, etching, laser, and sand paper, and wherein the dual-level layer is formed on the top of the main layer using at least one of NC discharge, etching, laser, and sand paper.

12. The method as claimed in claim 10, wherein the dual-level layer comprises:

a protrusion layer part including one or more protrusions protruding from the main layer; and

a recess layer part including one or more recesses recessed in different depths on the main layer.

13. The method as claimed in claim 10, wherein the deposition layer is formed by a metal film which is formed by depositing a metal material containing at least one of tin, silicon, titanium, aluminum, chrome, and stainless steel, and wherein the metal film is deposited at a thickness in the range of 0.01 to 0.1 μ

m on the surface of the injection-molded product.

14. The method as claimed in claim 10, wherein the clear coating is coated at a thickness in the range of 15 to 20 μ

m.

15. The method as claimed in claim 10, further comprising forming a base coating on the top of the deposition layer after depositing the deposition layer, the base coating increasing the luminescence of the deposition layer and providing a color sense for the deposition layer, wherein the base coating is coated at a thickness in the range of 5 to 10 μ

m between the deposition layer and the clear coating.

16. The method as claimed in claim 10, further comprising pre-processing the surface of the injection-molded product prior to depositing the deposition layer, thereby providing a pre-processed surface part, wherein one of nitrogen gas, oxygen gas and argon gas is used for pre-processing the surface of the injection-molded product.

17. The method as claimed in claim 16, further comprising forming a base coating on the top of the deposition layer after depositing the deposition layer, the base coating increasing the luminescence of the deposition layer, and providing a color sense for the deposition layer, wherein the base coating is coated at a thickness in the range of 5 to 10 μ

m between the deposition layer and the clear coating.
