A shell and its manufacturing method

Abstract

The embodiment of the invention discloses a manufacturing method of a shell. The method comprises the steps as follows: connecting a nonmetal portion to a metal portion via an integrated injection molding process so as to integrate the metal portion and the non-metal portion; performing first surface processing to the metal portion to make the metal portion show a first preset color; performing second surface processing to the nonmetal portion to make the nonmetal portion show a second preset color; and performing grooving processing to a preset position of the metal portion, wherein the preset position is a position, at a preset distance away from the joint of the metal portion and the nonmetal portion, of the metal portion. Uneven colors brought while performing second surface processing to the nonmetal portion could be removed after performing the grooving processing to the preset position of the metal portion. The transition of the color of the metal portion and the color of the nonmetal portion is smoothed through the natural metal color of the groove, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a casing and a manufacturing method thereof. Background technique [0002] With the increasing development of mobile phone terminals, people are not only satisfied with high hardware performance of mobile phones, but also require more refined and beautiful mobile phone bodies. At present, there are mobile phones with integrated metal and plastic casings on the market, but due to the problem of the antenna signal of the mobile phone, a part of the mobile phone casing must be hollow to ensure that the mobile phone signal is not affected by the metal. There is no way to make a mobile phone case that is 100% pure metal in the existing technology, and the hollowed out part of the mobile phone case is usually filled with materials such as plastic or glass that do not shield signals. Currently, there are two methods for filling the hollowed out part: [0003] The first treatment meth...

AI Technical Summary

Problems solved by technology

[0003] The first treatment method is to assemble the hollow part with plastic or glass. The advantage of this solution is that the assembled plastic or glass can use various processes (such as painting, electroplating, printing, etc.), so that the color of the whole machine is more abundant. , and its disadvantage is that the whole machine is not integrated, and there will be tolerances and gaps in assembly, giving people an unrefined feeling;

[0004] The second treatment method, the hollow part adopts the method of integrated injection molding process to make the metal and plastic seamlessly connected together, and the advantage of nano-injection molding and other processes is that the whole machine is integrated and it is exquisite and high-end, but its disadvantage is that it is injection-molded. Plastic can only be the natural color of plastic, such as the natural color of plastic materials such as black, white, gray, and yellow. Such plastic can only be black and white. This will affect the consistency of the whole machine because of the large color difference between plastic and metal. thereby affecting the user experience
