However, there are currently two ways to mark the surface of a plastic body. The first type is to apply electroless plating on the surface of the plastic shell to form a coating, and then print the image on the surface of the coating. It is a smooth surface, so the printed image is easy to fall off and not fixed. The second way is to print the image before the surface of the article, and then apply a chemical coating on the surface of the plastic shell after the surface of the image is covered - (four) (such as a layer of ink), and then the spacer is washed away with the medicament. However, when cleaning the isolation layer, it is difficult to grasp the depth of cleaning, and it is easy to damage the printed layer and affect the quality of the printed image. Therefore, there are two ways to form a graphic on the four sides of the plastic casing. SUMMARY OF THE INVENTION In order to improve the quality of the printed image on the surface of the existing plastic casing, the quality of the image is not good. 4 200944393 The main purpose of the present invention is to provide a plastic casing which can fix the graphic and can display the marked graphic. Manufacturing method. Based on the above object, the main technical means of the present invention is to provide a method for manufacturing a plastic case having a surface and a graphic, the process comprising: a method for manufacturing a plastic case having a surface and a graphic, the process comprising: taking a plastic The shell is coated with a conductive layer on the surface of the plastic shell; printed on the surface of the conductive layer: a predetermined layer on the surface of the plastic shell forms a printed layer; electroplating: electroplating on the surface of the plastic shell, the metal ions are electrically conductive The surface of the layer is formed-plated, that is, after the above-mentioned technical means is exhibited on the surface of the plastic casing to reveal the printed layer and the thick layer of the ore layer, the specific benefit obtainable by the present invention is fixed on the surface of the plastic casing: The invention is printed on the surface of the plastic casing, and the basin m can be infiltrated into the conductive layer: 'the surface of the plastic casing is further electroplated in a region other than the printed layer: the plating layer, regardless of the printed layer, is shown in FIG. 4; Or print the outer layer of the logo on the horse, and then in the printing | then the layer formed in the layer of the map & 'all can achieve a clear 顚 _ + π J month " Graphic and the purpose of not falling off. 2. It can form a three-dimensional label graphic: The thickness of the plating layer and the printing layer can be controlled at the time of creation, and the image indicated by the 为 is a dog-like shape or a concave shape to form a three-dimensional labeling effect. [Embodiment] 5 200944393 Please refer to the manufacturing method of the plastic case with the surface provided by the present invention as shown in the first and third figures, the process of which includes: taking a plastic casing (10); (10) Surface coating a conductive layer (100): Since the plastic shell (10) is a non-conducting body, it is required to be electroplated after the crucible, so that the surface needs to be electrically conductive first, for example, by applying bronze treatment (Br〇nzjng). , Graphitization, Metallic paints or Metalizing, forming a conductive layer on the surface of the plastic casing (1〇)

In addition, according to this method, other forms of displaying the text can also be used. Please refer to _4 and 5, not in plastic. The surface of the casing (20) is covered with a conductive layer (200), and then printed to form a printed layer (21) outside the scope of the slave image. Therefore, 6 200944393 forms a hollow in the range of the printed layer (21). In the graphic part (2彳〇), since the conductive layer (2〇〇) is in the area of the graphic part (210), when the electroplating step is applied, a plating layer is formed in the hollowed-out image portion (21〇) ( 22), the plating layer (22) may also be between the surface of the printed layer (21) or lower than the printed layer (21) to cause a three-dimensional marking effect of protrusion or recession. In addition, the present invention can also pre-form a graphic groove (3〇〇) on the surface of the plastic casing (30) as shown in the sixth figure, and the groove (3〇〇) is composed of φ. After the surface of the plastic case (3G) is covered with a conductive layer (301), a layer of the printed layer () is printed on the surface of the groove (3〇〇) and then known to be electroplated. A plating layer (32) is formed around the printed layer (31). 'Because the printed layer (31) is disposed in the concave groove (300), it can prevent the stereoscopic effect of the concave graphic from being generated.
