Embodiment 1

[0034] see Figure 1 to Figure 6 , the preparation method of the mobile phone casing provided by this embodiment comprises the following steps:

[0035] S1, the material preparation process is to prepare the metal substrate 10 for preparing the mobile phone casing 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 good strength and appearance processing surface , but also conducive to the production of various appearance effects, such as drawing, highlighting, etc.;

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

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

Embodiment 2

[0054] see Figure 7 , and combine Figure 3 to Figure 6 , the embodiment of the second 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 process of the step structure 14. for:

[0055] The outline of the frame of the mobile phone case 100 is processed into a stepped structure 14, which is arranged on the stamped metal substrate 10 at a position close to the antenna slot 30 to perform the bending process. The folding parts 13 are completed at the same time, which can save processing time and reduce processing cost.

Embodiment 3

[0057] see Figure 8 , and combine 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 process of the step structure 14. for:

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

[0059] Examples of mobile phone casings:

[0060] see Figure 1 to Figure 8 , the preferred embodiment of the mobile phone casing of the present invention will be described below.

[0061] The present invention also provides a ...

Abstract

The invention discloses a method for manufacturing a mobile phone shell. The method comprises the steps of preparing a metal substrate used for manufacturing the mobile phone shell; punching the metal substrate; bending the position, close to an antenna slot, of the punched metal substrate to obtain a bent part; conducting upsetting and extrusion on the bent part; conducting injection molding on the metal substrate to obtain a required plastic part; conducting filling injection molding on the bent part; conducting surface treatment on the metal substrate, the plastic part and filled plastic. By punching the metal substrate firstly, then conducting bending, upsetting and extrusion on the position, close to the antenna slot, of the metal substrate, obtaining the required plastic part through injection molding on the metal substrate, conducting plastic supplement, and finally conducting surface treatment on the whole workpiece, the method has the advantages that time for conducting surface treatment on the metal substrate can be shortened and production cost can be saved compared with the prior art. The invention further provides a mobile phone shell.

Description

technical field [0001] The invention relates to the technical field of mobile phones, in particular to a preparation method of a mobile phone casing and a mobile phone casing processed by the preparation method. Background technique [0002] The current preparation method of the mobile phone case is as follows: firstly prepare a required metal substrate; then, punch out the frame outline and antenna slot for making the mobile phone case from the metal substrate; then, use a CNC machining center to perform surface processing on the metal substrate; 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, the metal substrate and the plastic parts are surface-processed by a CNC machining center. It can be seen that CNC machining centers are generally used for surface processing of relevant parts of mobile phone casings. However, CNC machining centers are limit...
