specific Embodiment approach 1

[0035] The manufacturing process of the electronic product casing, the present embodiment takes the manufacture of the back cover of the mobile phone as an example, including the following steps:

[0036] Step 1: Prepare the explosion-proof membrane, including:

[0037] (A) Process the basic explosion-proof film with OCA optical adhesive to obtain the required explosion-proof film, including:

[0038] (A1) UV drawing transfer printing on the basic explosion-proof film with OCA optical adhesive;

[0039] (A2) The non-OCA surface of the explosion-proof film obtained in A1 is placed on a UV wire drawing die covered with UV liquid, and the roller is pressed evenly, and the texture on the UV die is transferred to the explosion-proof film;

[0040] (A3) the anti-explosion film obtained in A2 is subjected to UV light irradiation and cured to form a stable texture;

[0041] (B) electroplating the explosion-proof film after UV transfer printing in A to form a coating layer;

Abstract

According to the electronic product shell manufacturing technology, compared with an existing product, the produced electronic product shell is small in electronic signal interference, good in impact resistance and low in price, and meanwhile various shapes and colors can be manufactured according to market requirements. According to the invention, the UV wiredrawing is adopted to transfer the texture, the coating layer is adopted, and the ground color is printed on the coating layer; and the three structural layers can realize the color effects of single color, darkness, gradient color, high-brightness dazzling color, high-brightness color, high-brightness gradient color and multiple colors including but not limited to partition colors in a manner of combining the three structural layers according to the required color effect. According to the method, laser etching of the explosion-proof film, attaching of the bearing film and CNC machining treatment are adopted, and the problem of a combination gap between the explosion-proof film and the electronic product shell after traditional attaching is solved. A series of problems in the manufacturing process of an existing electronic product shell are solved.

Description

technical field [0001] The invention relates to the field of glass thinning, in particular to a manufacturing process of an electronic product casing. Background technique [0002] At present, most electronic product casings in the market, (1) in terms of product structure, such as mobile phones, tablet computers, display screens and other casing products are metal casings, glass casings, injection molding single-product casings, ceramic casings, etc. (2) In terms of product design: At present, the injection molding 3D product drawings designed outside the market do not consider the post-manufacturing process, and the product design structure is single, which makes it impossible to carry out the combination of multiple processes such as curtain coating, lamination, printing, and CNC blanking. , The product performance is single, and the design use is limited. (3) In the production of compression injection molds: At present, the development of external molds, the design of m...
