Colored plastic mobile phone front cover manufacturing process

Abstract

The invention discloses a colored plastic mobile phone front cover manufacturing process which is characterized in that compared with an existing colored plastic mobile phone front cover, a hole site (7) for mounting a camera is formed in the colored plastic mobile phone front cover (6), and fixedly connected reinforcing ribs (8) are arranged at four corners and four edges of the colored plastic mobile phone front cover (6); the reinforcing rib (8) and the colored plastic mobile phone front cover (6) are seamlessly and fixedly connected or integrally formed, the colored plastic mobile phone front cover (6) sequentially comprises a shading layer (5), a reflecting layer (4), a shell layer (1), a texture layer (2) and a functional coating (3), and according to actual requirements, L * a * b * values of the colored plastic mobile phone front cover (6) comprise a * and b * values of the shell layer (1) and L * values of the reflecting layer (4). A series of problems existing in the colored plastic mobile phone front cover manufactured by the mobile phone shell front cover manufacturing process are solved.

Description

technical field [0001] The invention relates to the field of manufacturing a colored plastic mobile phone front cover, in particular to a manufacturing process of a colored plastic mobile phone front cover. Background technique [0002] In the process of making the front cover of colored plastic mobile phones, the color difference formula of the color difference meter is commonly used in the industry: CIE L*a*b* color space, L*,*a,b* is the chromaticity value representing the color of the object , that is, the color space coordinates of the color, any color has a unique coordinate value; where L* represents light and shade (black and white), *a represents red and green, and b* represents yellow and blue; it is a modern color difference assessment according to the International Lighting Association. The standard color difference formula recommended by (CIE) and calculated by instruments and computers can be expressed by precise numbers. [0003] The color L*, a*, b* of the c...

Problems solved by technology

This will bring the following problems: (1) The more color layers of the coating layer, the more dispersed the color difference of the coating layer, which will lead to lower yield

(2) Because the coating layer needs to use high refractive index materials, but its thickness is generally only between 5-100nm, a slight change in its thickness will cause a large color difference, because the more coatings, the color levels displayed by the coating layer will result feel bad

(3) When the decorative film is pasted on the inner surface of the 3D plastic shell, the more layers are required, the thicker the coating layer is, and the easier the coating layer is to break in areas with greater stress and strain, resulting in poor appearance

(4) Moreover, there are no protective measures for the edge of the front cover of the colored plastic mobile phone and the camera, which is easy to damage the camera and the front cover during the installation process

(5) There are no protective measures for the four corners of the front cover of the mobile phone, which is prone to damage during the installation process

(6) The front cover and frame of the mobile phone are set separately, which is not conducive to the assembly of the mobile phone, and there are gaps after assembly
