After the anode 1 of the nameplate i is anodized, various colors can be colored as needed, and various patterns can be formed. Due to the characteristics of the anodizing treatment, the pattern of the coloring or formation has a relatively strong force, a wear resistance, a surface hardness and a rice resistance, and has a better gloss without a break. Since the first frame 丨丨 and the second frame 16 are metal frames, they have a bright metallic luster, which has a better decorative effect and gives the user a pleasing feeling. The manufacturing method of the nameplate 1 of the present invention mainly comprises the following steps: (1) manufacturing a metal substrate, and applying a protective film on a part of the substrate; (2) anodizing the metal substrate; (3) metal The substrate is subjected to a film-removing treatment, and the protective film is removed to expose a part of the metal substrate. (4) The metal substrate is press-formed to form a nameplate. The metal substrate is preferably an aluminum plate. In the step (1), the aluminum plate is first opened according to the size of the nameplate 1, and subjected to mechanical polishing, degreasing cleaning, chemical polishing, water washing, drying, etc., and then in a part of the metal substrate (including the first The first frame 11 and the second frame j 6) shown in the figure are coated with a protective film. The method of applying the protective film may be a screen printing method in which an acid-resistant ink is printed in a predetermined coating zone and dried and hardened to protect the region from anodization in the next step. Since the surface of the aluminum plate which is not printed at this time (including the substrate 10 shown in the first figure) may be partially oxidized, the oxide film may be removed by chemical etching and washed and dried to facilitate the next anodic oxidation treatment. Forms I A0101 Page 6 / Total 16 Pages 0993209110-0 1329142 June 15th, 999 Nuclear Replacement Page [0014] In step (2), the anode treatment uses the above aluminum plate as the anode and lead as the cathode. 100~200g/L of sulfuric acid solution is passed through a direct current for anodic oxidation, wherein the DC voltage is 8~16V, and the current density is 100. 0~200. OA/m2, which can be formed by oxidation treatment after 30~50 minutes. It is an anodized film of 8~15"ιη; the anodized plate is washed into water and placed in a coloring tank. The coloring tank contains an organic dye solution with a concentration of 1~l〇g/L, and the aluminum plate is in the organic dye solution. After soaking for 5~20 minutes, remove and rinse the residual dye solution attached to the surface of the aluminum plate; then put the aluminum plate into boiling water to seal the anodized film, take it out after drying for about 30 minutes, and if the ink is not printed on the surface of the aforementioned nameplate A colored anodized film is formed on the region (including the substrate 10). The type of the organic dye may vary depending on the intended color, and the aluminum plate may be colored by a conventional inorganic dye coloring, electrolytic coloring or integral coloring method to form various colors on the surface of the aluminum plate. [0015] In the step (3), the film-removing treatment uses the printing ink of the coating zone in the conventional solvent cleaning step (1) to expose the substrate. [0016] In the step (4), the aluminum plate is stamped into the nameplate 1 shown in FIG. 2 by a conventional stamping process, that is, the first opening 12 and the second opening 14 are formed on the base 10, and A regular, bright metal frame, that is, a first frame 11 and a second frame 16 are formed around the base 10 and the first opening 12. [0017] In order to prevent oxidative discoloration of the metal frame, the method for manufacturing the nameplate 1 may further include the step of post-processing the gold eyebrow frame, such as plating the surface of the metal frame, thereby making the surface hardness and the durability of the metal frame surface. The weather resistance, oxidation resistance, etc. are improved, and the surface brightness is improved to have a better decorative effect. The chrome plating process can be physical vapor deposition 091133444 Form No. A0101 Page 7 / Total 16 Page 0993209110-0 1329142 On June 15, 099, according to the Physical Vapor Deposition (PVD) vacuum key chromium nitride process, In the vacuum coating machine, the first nameplate 1 is held in the vacuum chamber of the coating machine, and the vacuum is introduced into the vacuum chamber, such as argon gas, so that the pressure in the vacuum chamber is 7. 0x1 0_3~9x1 0_3 Pascal When the nameplate 1 is applied with a bias voltage of -950~-1100 volts, the argon gas is subjected to a neon discharge, and the argon ion bombards the surface of the metal frame of the nameplate 1 to perform ion cleaning thereof. After about 10 to 20 minutes, the vacuum chamber is adjusted. The air pressure is 4. 0 χ10_3~6χ1 (Γ3 Pascal, the metal frame surface is further cleaned by the chromium ions sputtered from the target. When the metal frame surface of the nameplate 1 is completely cleaned, the nitrogen gas is introduced into the vacuum chamber t, and the adjustment is applied to the nameplate. After the bias voltage of 1 is 0~-500 volts, nitrogen reacts with chromium ions to form CrN and deposits on the surface of the metal frame of the nameplate 1. The volume ratio of nitrogen to argon is higher than that of the CrN film produced. The effect, in order to reduce the deposition of pure Cr, partial reaction Cr, Cr2N, the volume ratio of argon to nitrogen should be less than 1, preferably in a pure nitrogen environment to deposit CrN film, the CrN film layer thickness of 1 ~ 9 microns. [0018] The chrome plating step may be performed before the metal substrate is coated with the protective film, and only part of the metal substrate (including the first frame 11 and the second frame 16 shown in the first figure) is chromed, and other regions ( The base body 10) shown in the first figure should be shielded and protected. After chrome plating, a protective film is applied on the surface of the chrome plating layer, and then formed into a nameplate by the above-mentioned anodizing, film-removing and stamping steps. After the above anodizing treatment, in this case, chrome plating is performed, and the anodized region (ie, the substrate 10 shown in the second figure) should be shielded to prevent the anodized region from being chrome-plated. [0019] The above-mentioned nameplate 1 may be made of a metal substrate such as Made of aluminum plate, it can also be molded out of plastic substrate 10, and then sputtered on the surface of the substrate 10 by sputtering or other conventional methods.

[0020] It can be understood that the above step (4) can be carried out in the step (1), that is, the metal substrate is first pressed by the nameplate 1 The size and contour are stamped into the base 10, and then processed by the steps (2) and (3) to form the nameplate 1.

The color anodized film and the metal frame on the surface of the nameplate 1 have a glamorous visual effect and are contrasted with the body of the mobile phone 2, so that the mobile phone 2 is elegant and elegant, and adds value. [0022] The nameplate 1 of the present invention can be used as a component of other devices, and can also be used as medals, medals, nameplates, signs, etc., and can be designed into different shapes according to their different uses. [0023] Compared with the prior art, since the nameplate of the present invention has a colored substrate and a metal frame which are oxidized by the male plate, the color of the nameplate is uniform, the color is rich, the gloss is bright, and the decorative effect is noble and elegant. The method for manufacturing the nameplate of the present invention is simple in steps and low in cost.
