Problems solved by technology

The back cover of the mobile phone in the prior art is generally made of plastic materials. Due to the limitation of the plastic material, although the back cover of the mobile phone made of it has good toughness and can prevent falling, the appearance effect is poor.
Based on this, some mobile phone back covers are made of glass to improve the appearance, but the cost of glass is high and it is easy to break
[0003] At present, the back covers of mobile phones manufactured in the prior art either have performance problems, such as strength, hardness, etc., or have appearance problems, such as light transmittance, rainbow marks, etc.
And as users have higher and higher requirements for mobile phones, the existing mobile phone back cover cannot meet the demand

Embodiment 1

[0042] The first embodiment provides a method for manufacturing a mobile phone back cover.

[0043] Please refer to figure 1 , the method includes the following steps:

[0044] S100, adding polymethyl methacrylate material to the injection mold, and obtaining the material after injection molding;

[0045] S200, cleaning the above materials;

[0046] S300, hardening the cleaned material;

[0047] S400. Finishing the hardened material to obtain the basic profile;

[0048] S500, automatic spraying line for the inner surface of the basic profile for coloring.

[0049] In the above-mentioned production method, since polymethyl methacrylate is used as a raw material for production, polymethyl methacrylate has better performances, including physical properties, light transmission properties and chemical properties, etc., for example, physical properties have The advantages of light weight, high mechanical strength, good light transmission performance, stable chemical properties,...

Embodiment 2

[0074] The second embodiment provides a method for manufacturing the back cover of the mobile phone.

[0075] Please refer to figure 2 , the production method includes the following steps:

[0076] S1000, processing the polymethyl methacrylate material to form a basic profile;

[0077] S2000. Take a polyethylene terephthalate diaphragm, and color the polyethylene terephthalate diaphragm by optical plating;

[0078] S3000, cutting and hot-pressing the colored polyethylene terephthalate film to form a sheet.

[0079] S4000. Paste the sheet on the inner surface of the basic profile.

[0080] Thus, in this embodiment, since polymethyl methacrylate is used as raw material for production, since polymethyl methacrylate has better performances, including physical properties, light transmission properties and chemical properties, etc., such as physical properties It has the advantages of light weight, high mechanical strength, good light transmission performance, stable chemical p...

Embodiment 3

[0095] This embodiment provides a method for manufacturing a mobile phone back cover.

[0096] Please refer to image 3 , the production method includes the following steps:

[0097] S100, adding polymethyl methacrylate material to the injection mold, and obtaining the material after injection molding;

[0098] S200, cleaning the above materials;

[0099] S300, hardening the cleaned material;

[0100] S400. Finishing the hardened material to obtain the basic profile;

[0101] S600. In a vacuum environment, use optical plating to process the inner surface of the basic profile for coloring.

[0102] In this way, due to the use of polymethyl methacrylate as raw material for production, due to the better performance of polymethyl methacrylate, including physical properties, light transmission properties and chemical properties, such as physical properties such as light weight and mechanical strength High advantages, good light transmission performance, stable chemical propert...

Abstract

The invention discloses a mobile phone rear cover manufacturing method and a mobile phone rear cover. The manufacturing method includes: processing a polymethyl methacrylate material to form a base profile; taking a polyethylene glycol terephthalate diaphragm, and coloring the polyethylene glycol terephthalate diaphragm by an optical coating method; subjecting the colored polyethylene glycol terephthalate diaphragm to cutting and hot press molding to form a sheet; laminating the sheet onto the inner surface of the base profile. The mobile phone rear cover manufacturing method has the advantages that the manufactured mobile phone rear cover is resistant to drop and wear, an appearance effect can be improved, and manufacturing cost is reduced as compared with that of a manufacturing method using glass.

Description

technical field [0001] The invention relates to the technical field of mobile phone accessories, in particular to a method for manufacturing a mobile phone back cover and the mobile phone back cover. Background technique [0002] The back cover of the mobile phone is used as the back accessory of the mobile phone. On the one hand, it can protect other parts inside the mobile phone, and on the other hand, it can also improve the appearance of the mobile phone. The mobile phone back cover in the prior art is generally made of plastic material. Due to the limitation of the plastic material, although the mobile phone back cover made by it has good toughness and can be anti-drop, the appearance effect is poor. Based on this, some mobile phone rear covers are made of glass to improve the appearance effect, but the cost of glass is relatively high and it is easy to break. [0003] At present, the mobile phone back covers manufactured in the prior art either have performance proble...
