A mobile phone case with 3D structure and its processing technology

Abstract

The invention discloses a mobile phone shell with a 3D structure. The shell comprises a surface shell body and a bottom shell body. The surface shell body and the bottom shell body comprise sheet material layers which are made of a transparent material and possess outer transparent surfaces and inner transparent surfaces, hardening layers which form on the outer transparent surfaces and possess a predetermined thickness, local printing layers which form at any local positions of the inner transparent surfaces, texture transfer printing layers which form on the inner transparent surfaces and cover the local printing layers, vacuum electroplated layers and printing ink layers, wherein the vacuum electroplated layers and the printing ink layers are successively superimposed with the texture transfer printing layers. The invention also discloses a processing technology. By using the mobile phone shell with the 3D structure, on one hand, the shell possesses light transmittance performance which is similar to the light transmittance performance of glass, simultaneously can bear a large impact force and can not be fragmented so that a durability problem during a usage process is solved, and the shell accords with human engineering of a hand portion of a person and satisfies a customized demand of a consumer; on the other hand, through the above technology, mass production in industry is realized and production cost is reduced.

Description

technical field [0001] The invention relates to a mobile phone casing with a 3D structure and a processing technology thereof. Background technique [0002] With the development of mobile communication terminals, such as mobile phones, have become daily personal consumer electronic products. According to the market demand formed by the majority of users, the thinning and refinement of the appearance of mobile communication terminals such as mobile phones and appearance structural parts will gradually lead the development direction of current and future mobile communication devices. At present, in the production and processing of the 3D structure of the mobile phone cover and back cover, the realization methods include injection molding and glass high-pressure molding. Although the former is mature in technology, it has less effect in appearance design and is now in the mainstream design. The latter is a new process, although there is a large market demand, but because the p...

Problems solved by technology

At present, in the production and processing of the 3D structure of the mobile phone cover and back cover, the realization methods include injection molding and glass high-pressure molding. Although the former is mature in technology, it has less effect in appearance design and is now in the mainstream design. The latter is a new process, although there is a large market demand, but because the process is not mature enough, the yield rate is low, the cost is too high, and the product has a fragile safety problem

Therefore, it is difficult to popularize this process in the mass production of mobile phones, and it will take time to promote and apply it in the industry

[0003] The mobile phone shells that appear in the market usually use simple printed patterns to decorate the surface of the mobile phone shell, or use spraying technology to beautify the shell of the mobile phone. Seriously affect the appearance of the phone

[0004] At present, there is no simple and effective solution for the product quality problems and process cost problems in the production process of the 3D mobile phone cover and back cover.
