Embodiment 1

[0034] see Figure 1 to Figure 6 , the preparation method of the mobile phone shell that the present embodiment provides, comprises the following steps:

[0035] S1, the material preparation process, preparing the metal substrate 10 for preparing the mobile phone case 100, wherein the material of the metal substrate 10 is stainless steel, aluminum or aluminum alloy, so as to ensure that the metal substrate 10 has better strength and appearance processing surface , and it is also beneficial to produce various appearance effects, such as brushed, high-gloss, etc.;

[0036] S2, the stamping process, the metal substrate 10 is stamped to stamp out the frame outline of the mobile phone casing 100 and the antenna slot 30 for installing the antenna, the frame outline on the metal substrate 10 includes a first side 11 and a second side 12 , specifically, the antenna slot 30 is provided on the first side 11;

[0037] S3, the bending process, because in the previous process, in order t...

Embodiment 2

[0054] see Figure 7 , and combined with Figure 3 to Figure 6 , the embodiment of the second embodiment is similar to the embodiment of the first embodiment. For details, refer to the embodiment of the first embodiment, which will not be described in detail here. The difference between the two lies in the processing procedure of the step structure 14. The specific embodiment of the second embodiment for:

[0055] A step structure 14 is processed out of the frame outline of the mobile phone casing 100 and placed on the stamped metal substrate 10 near the antenna groove 30 for bending processing. In this way, the step structure 14 and the bent structure can be formed at one time through the mold. The folding part 13 is completed at the same time, which can save processing time and reduce processing cost.

Embodiment 3

[0057] see Figure 8 , and combined with Figure 3 to Figure 6 , the embodiment of the third embodiment is similar to the embodiment of the first embodiment. For details, please refer to the embodiment of the first embodiment, which will not be described in detail here. The difference between the two lies in the processing procedure of the step structure 14. The specific embodiment of the third embodiment for:

[0058] Process the outline of the frame of the mobile phone case 100 into a stepped structure 14. The step is set between the step of stamping the metal substrate 10 and the step of bending the stamped metal substrate 10 at a position close to the antenna groove 30, that is, this Processing as individual steps. In this mode, the mold processing is relatively simple and the cost is relatively low.

[0059] Examples of cell phone cases:

[0060] see Figure 1 to Figure 8 , the best embodiment of the mobile phone casing of the present invention is set forth below. ...

Abstract

The method for preparing a mobile phone case of the present invention comprises the steps of: preparing a metal substrate for preparing the mobile phone case; stamping the metal substrate; bending the stamped metal substrate at a position close to the antenna groove, Bending part by bending; pier extrusion processing on the bending part; injection molding processing on the metal substrate to injection mold the required plastic parts; filling injection molding on the bending part; metal substrate and plastic parts And filling plastic for surface treatment. The preparation method of the present invention mainly includes stamping the metal substrate first, then bending and extruding the position of the metal substrate close to the antenna groove, and then injecting the required plastic parts on the metal substrate, and In plastic repair, finally, surface treatment is carried out on the entire workpiece. Compared with the preparation method of the prior art, the time required for surface processing of the metal substrate can be reduced, and the production cost can be saved. The invention also provides a mobile phone case.

Description

technical field [0001] The invention relates to the technical field of mobile phones, in particular to a method for preparing a mobile phone case and a mobile phone case processed by the preparation method. Background technique [0002] The current preparation method of the mobile phone shell is as follows: first prepare a required metal substrate; then, punch out the frame outline and antenna groove for making the mobile phone shell on the metal substrate; then, use a CNC machining center to process the surface of the metal substrate; and then Next, plastic parts are injection-molded on the metal substrate to isolate the conduction between the metal substrate and the antenna when the antenna is installed; after that, a CNC machining center is used to process the surface of the metal substrate and plastic parts. It can be seen that when processing the surface of the relevant parts of the mobile phone casing, CNC machining centers are generally used for processing. However, C...
