Example Embodiment

[0029] see figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the method for realizing single-color dual-gloss of the present invention.

[0030] In this embodiment, the method for realizing monochromatic dual gloss comprises the following steps:

[0031] S100, electroplating to form a non-conductive coating layer, the non-conductive coating layer is formed on the substrate.

[0032] The electroplating in this step can be carried out by water plating or NCVM process. In this embodiment, the NCVM process is used. The NCVM process can make a metal appearance effect and beautify the surface of the workpiece. The thickness is less than 0.3μm, such as 0.1μm or 0.2μm, the non-conductive coating layer has no conductivity. When the digital product receives or transmits a signal, the generated electromagnetic field is not accumulated by the coating layer, so it does not affect the digital product. Radio frequency performance and electrostatic discharge perfo...

Abstract

The invention discloses a method for realizing monochromatic double-luster, a plastic housing and a terminal. The method comprises the following steps: metallization is carried out to form a non-conductive coating which is formed on a base material; after the metallization step, an UV finish is sprayed to form an UV finish layer; laser etching is carried out on a part of areas of the UV finish layer so as to form a laser etching area; and spraying or covering operation is no longer carried out on the UV finish layer. Through the above mode, comparison between a shiny finish and a matt finish can be realized, and luster is no longer single. In addition, the laser etched UV finish layer is used as the outermost layer of the plastic housing, and spraying or covering operation is no longer carried out on the UV finish layer. Thus, the laser etching area is exposed to the surface of the product so as to make the comparison between the shiny finish and the matt finish of the plastic housing's surface to be more distinctive and make texture to be more excellent.

Description

technical field [0001] The invention relates to the field of plastic casing processing technology, in particular to a method for realizing single-color double-gloss, a plastic casing and a terminal. Background technique [0002] NCVM (Non conductive vacuum metalization), that is, vacuum non-conductive electroplating, also known as discontinuous coating technology, is a high-tech originating from ordinary vacuum electroplating. Vacuum electroplating, referred to as VM (vacuum metalization), refers to the organic conversion of metal materials under vacuum conditions by using specific means such as chemistry and physics, so that metals are converted into particles, deposited or adsorbed on the surface of plastic materials to form a film, that is, What we call coating. NCVM uses thin films such as metal and insulating compounds to be plated, and uses the discontinuous characteristics of each phase to obtain a metal texture in the final appearance without affecting the effect of...
