Preparation process of injection-molded mobile phone shell

Abstract

The invention discloses a preparation process of an injection-molded mobile phone shell. The preparation process mainly comprises the steps of preparing a colored explosion-proof film, preparing the injection-molded mobile phone shell, carrying out 3D vacuum lamination on the colored explosion-proof film and the injection-molded mobile phone shell, carrying out CNC processing and the like. According to a preparation process for the colored explosion-proof film in the invention, UV wiredrawing texture, a coating layer and an ink layer are adopted, and the three structural layers are combined according to required color effects to achieve multiple color effects including a single color, a dull color, a gradient color, a highlight dazzling color, a highlight color, a gradient color and the like. The colored explosion-proof film and the injection-molded mobile phone shell are laminated firstly and then subjected to CNC size and shape processing, so the problem of a combination gap betweenthe film and the mobile phone shell in traditional lamination is solved. Meanwhile, the process design of the injection-molded mobile phone shell is changed; through a rib position design, the structural strength of the product is improved and the warping degree of the product is reduced; the size manufacturing precision of subsequent procedures is improved through a positioning hole design; and ashower coating overflow problem is solved through the design of a plane structure, and product yield is improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone case production and manufacturing, in particular to a preparation process of an injection-molded mobile phone case. Background technique [0002] At present, the mobile phone case products on the market are metal cases, glass cases, injection-molded single-product cases, ceramic cases, etc. The metal cases and ceramic cases made by the existing technology have a greater degree of signal interference, which is not conducive to the use of mobile phones in the future 5G market. The impact resistance of the shell is poor, and the production cost is high, and the existing injection-molded single-product shell cannot achieve multiple color effects. In terms of product design, 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 combine multiple processes such as ...

[0002] At present, the mobile phone case products on the market are metal cases, glass cases, injection-molded single-product cases, ceramic cases, etc. The metal cases and ceramic cases made by the existing technology have a greater degree of signal interference, which is not conducive to the use of mobile phones in the future 5G market. The impact resistance of the shell is poor, and the production cost is high, and the existing injection-molded single-product shell cannot achieve multiple color effects

In terms of product design, 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 combine multiple processes such as spray coating, lamination, printing, CNC blanking, etc., and product performance Single, limited design use
