[0002] As companies need to build their brands, more and more products are designing iconic LOGO patterns to showcase their product value. People strengthen their purchasing power through their recognition of the brand, thus generating huge benefits for the companies.

[0003] Most of the existing product LOGO patterns are printed on the product surface, and then attached with simple ordinary ink, which results in a relatively single color of the product, and the surface of the product LOGO pattern generally does not have a metallic luster, making the product LOGO pattern too ordinary and not conspicuous enough. Or by customizing metal products and then assembling them on the product, but there is a problem that the LOGO pattern will oxidize or fall off the product over time. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a method for making a metallic LOGO pattern on a product surface and a plastic product so that the LOGO pattern on the surface of the plastic product presents a metallic luster.

[0007] S2: spraying primer on the surface of the plastic product and performing UV curing;

[0008] S3: performing NCVM coating on the primer of the plastic product and spraying protective paint on the coating surface;

[0009] S4: removing the protective paint and the coating film in the area other than the LOGO pattern on the surface of the plastic product by laser engraving;

[0010] S5: removing the residual coating from the area outside the LOGO pattern;

[0011] S6: spraying topcoat on the surface of the LOGO pattern of the plastic product and performing UV curing.

[0012] Further, in step S2, spraying the primer includes spraying white paint as a first layer of primer, spraying a first intermediate paint on the surface of the white paint as a second layer of primer, and then performing UV curing.

[0013] Furthermore, baking is required after spraying the white paint and spraying the first intermediate paint.

[0014] Further, in step S3, the coating material is pure indium, and the coating method is evaporation.

[0015] Furthermore, in step S3, a first varnish is sprayed on the coating as a protective varnish.

[0016] Furthermore, UV curing is performed after spraying varnish.

[0017] Furthermore, in step S5, the residual plating film is removed by a stripping solvent, and the stripping solvent is composed of a mixed solution of alcohol, hydrochloric acid and water.

[0018] Further, in step S6, spraying the topcoat includes spraying a second intermediate paint as a first topcoat, spraying a second varnish on the surface of the second intermediate paint as a second topcoat, and then performing UV curing.

[0019] Furthermore, baking is required after spraying the second intermediate paint and spraying the second varnish.

[0020] The present invention further provides a plastic product, the surface of which has a LOGO pattern with a metallic texture, and the LOGO pattern with a metallic texture is manufactured by using the above-mentioned method for manufacturing a LOGO pattern with a metallic texture on the surface of a product.
