Mobile phone front cover manufacturing process

Abstract

According to the mobile phone front cover manufacturing technology, compared with an existing product, the produced mobile phone front cover 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, CCD positioning vacuum and CNC machining treatment are adopted, and the problem of a combination gap between the explosion-proof film and the front cover of the mobile phone after traditional attaching is solved. The mobile phone front cover and the frame are integrally formed, and compared with a traditional mobile phone front cover and a traditional frame, the mobile phone front cover and the frame do not need to be assembled and have no gap, and a series of problems in the manufacturing process of an existing mobile phone front cover are solved.

Description

technical field [0001] The invention relates to the field of mobile phone front cover manufacturing, in particular to a mobile phone front cover manufacturing process. Background technique [0002] At present, the existing manufacturing process of the back cover of the mobile phone case has the following shortcomings: (1) Process manufacturing: the metal and ceramic shells made by the existing manufacturing process have a large degree of signal interference, which is not conducive to the use of mobile phones in the future 5G market, and the glass shell has poor impact resistance. , the production cost is high, and the injection-molded single-product shell cannot achieve a variety of color effects. (2) Product process design: The structure design is single, the degree of warpage of the injection molding is large, and the multi-process combination cannot be carried out or the yield rate is low when the multi-process combination is carried out. (3) Compression injection mold p...

Problems solved by technology

[0002] At present, the existing manufacturing process of the back cover of the mobile phone case has the following disadvantages: (1) Process production: the metal and ceramic shells made by the existing manufacturing process have a high degree of signal interference, which is not conducive to the use of mobile phones in the future 5G market, and the impact resistance of the glass shell is poor , the production cost is high, and the injection molding single product shell cannot achieve multiple color effects

(2) Product process design: the structure design is single, the degree of warpage of injection molding is large, and the multi-process combination cannot be performed or the yield rate is low when multi-process combination is performed

(3) In the production of compression injection molds: the mold is not specially designed during the mold clamping and pop-up process. The traditional spring device during the mold clamping and pop-up process will easily lead to small compression, uneven force, and no mold contact surface. Additional treatment to make contact surfaces prone to wear

Therefore, the production thickness of the product will be unstable, the yield rate is low, the product thickness is too thick, and the service life of the mold is low.
