Problems solved by technology

[0002] With the development of science and technology, mobile phones are used more and more widely. Among them, the back cover of the mobile phone is one of the important parts of the mobile phone. The appearance effect is different according to the different production processes, and the traditional mobile phone back cover is generally made of plastic. Yes, various effects can be achieved by spraying various paints on the plastic shell, but the wear resistance of the plastic is poor and the strength is not enough, so that the outer surface of the plastic mobile phone back cover (the side of the mobile phone back cover facing the mobile phone motherboard is the inner surface, The side facing away from the main board of the mobile phone is the outer surface) is easy to be damaged or scratched. In order to improve the wear resistance and strength of the mobile phone back cover, it is also made of stainless steel, but this kind of stainless steel mobile phone back cover is too bulky to hold Therefore, there is a metal mobile phone back cover made of metal material on the market. Because aluminum has the advantages of light weight, high wear resistance, good hand feeling and high strength, the existing metal mobile phone back cover is generally Aluminum phone back cover
However, the metal characteristics of the aluminum mobile phone back cover will interfere with the signal, so that the battery cannot be charged wirelessly, and cannot be applied to the 5G network, and the back cover of the mobile phone will heat up after long-term use
And with the intensified competition in the processing of mobile phone back covers, the appearance requirements of mobile phone back covers are becoming more and more diverse, but the existing mobile phone back covers are generally a single solid color, the color is monotonous, and the appearance effect is poor, which cannot satisfy people. Requirements for mobile phone back covers that require a multi-color gradient appearance

Embodiment Construction

[0028] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0029] Examples, see attached Figure 1~Figure 2 , a 3D gradient mobile phone back cover molding process, which comprises the following steps:

[0030] 1. Cutting: use a glass cutting machine to cut the glass, and cut out a glass piece that matches the size of the back cover of the mobile phone when it is spread out. The thickness of the glass is 0.5-1.0mm;

[0031] 2. Hot bending forming: Use a glass hot bending machine to hot bend the glass sheet in step 1. When hot bending, put the glass sheet in step 1 at 80°C, 100°C, 200°C, 300°C, 400°C in sequence Heating and softening at lower temperature, followed by multiple downward hot pressing at 500°C for micro-deformation, and finally multiple downward hot pressing at 680°C to form a semi-finished glass back cover 1 whose shape matches the shape of the back cover o...

Abstract

The invention discloses a 3D gradient color mobile phone rear cover forming process and a mobile phone rear cover. The 3D gradient color mobile phone rear cover forming process comprises the followingsteps: cutting; hot bending forming; surface treatment; cutting is conducted; pattern processing; dip dyeing; electroplating is conducted; hardening treatment; punching and forming are conducted; merging molding. According to the 3D gradient color mobile phone rear cover, the glass rear cover and the PET film do not interfere with signals, so that the signals of a mobile phone are relatively strong, wireless charging can be realized, the 3D gradient color mobile phone rear cover is suitable for being applied to different networks, and the mobile phone rear cover has the effects of light weight, thinness, scratch resistance and heat dissipation, and is not easy to cause heating of the mobile phone. According to the 3D gradient color mobile phone rear cover forming process, the gradient color process is realized through dip dyeing; the mobile phone rear cover is provided with the gradient color layer, the dyed product is uniform in coloring and good in gradient effect, multiple colors can be dyed at the same time, the mobile phone rear cover has multiple colors, the appearance effect is more obvious, and the requirement of people for the mobile phone rear cover with the multi-colorgradient appearance is met.
