Abstract

The invention discloses a mobile phone and a manufacturing method of a surface decorative layer of an appearance piece thereof. The manufacturing method comprises the following steps of: applying a priming paint layer on the surface of the appearance piece of the mobile phone; making a metal coating with needed pattern on the surface of the priming paint; applying a middle paint layer on the surface of the metal coating and the surface of the priming paint at the periphery of the metal coating; and applying a finish layer on the surface of the middle paint. With the PPVD (Patterned Physical Vapor Deposition) technology, the NCVM (Non-conductive Vacuum Metallization), the screen printing film and the spraying technology are combined together, the manufactured decorative layer has stereo decorative effects with high metallic characteristics, the grade of the products is improved, and the decorative layer is free from limitation of the shape of products and can be manufactured on the surface of a curve appearance piece; in comparison with gold stamping, the manufacturing method can manufacture the complex patterns which have thin lines and are not prone to fracture, and the metal layer cannot be corrugated, cannot bubble and has strong adhesive force; in comparison with the laser etching, the decorative layer manufactured by the manufacturing method has no carving trail, and provides no handfeel when being touched; and moreover, the equipment cost is low, and the production efficiency is high.

Description

technical field

[0001] The invention relates to the field of manufacturing technology of surface decoration layers of appearance parts such as mobile phones and their front shells, middle shells, back shells or battery covers. A mobile phone with a high metallic three-dimensional decoration effect and a method for making a surface decoration layer of its exterior parts. Background technique

[0002] With the popularization of smart phones in the past two years, especially the emergence of tablet smart phones, the number of appearance parts of mobile phones has been greatly reduced, from the previous 6-9 parts to 2-3 parts, and the area of ​​the front shell It has also become very small, and only the battery cover part is still a large-area plane, so it is no longer possible to make various surface processing techniques like the previous mobile phone appearance parts.

[0003] In the past surface processing technology of mobile phone appearance parts, spraying, NCVM (Non-con...

Embodiment Construction

[0035] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.

[0036] In order to make the appearance of high-end products such as smart phones and tablet computers more high-end and more beautiful, the method for manufacturing the surface decoration layer of mobile phone appearance parts in the present invention combines three processes of NCVM, silk screen film and spraying, which is also called selective The process of vacuum plating is different from the traditional vacuum plating. The traditional vacuum plating is a whole piece of coating and cannot make a specific pattern. However, the present invention has a selective vacuum plating process combined with film to selectively retain the required coating. To remove unnecessa...
