preparation example Construction

[0021] According to the method for preparing the shell in one embodiment, the machining allowance is low, and a shell with better mechanical properties can be obtained. Further, the housing is in a 2.5D or 3D shape. Furthermore, the housing is a 3D mobile phone housing. It should be noted that the casing is not limited to a mobile phone casing, and may also be a casing of other electronic devices in the technical field, for example, a casing of a tablet computer, a computing device, or an information display device. In a specific example, the housing is a 3D mobile phone back cover.

[0022] Specifically, the method for preparing the shell includes the following steps S110-S120:

[0023] S110, placing the ceramic plate in a hot-bending mold, and performing pre-bending at 1000°C-1200°C.

[0024] The study found that if the pre-bending temperature is too low, the bending angle of the shell will be affected to affect the three-dimensional effect of the shell; if the pre-bendin...

Embodiment 1～14

[0065] The shells of Examples 1-14 were prepared according to the parameters in Table 1 and Table 2. Specifically, the preparation process of the shell is as follows:

[0066] (1) Mixing zirconia ceramic powder with organic components and molding to obtain a flat green body; degreasing the flat green body, and then sintering at T1°C for t1h to obtain a flat flat fired body with a thickness of D1mm; The flat-shaped sintered blank is subjected to flat grinding and rough polishing in sequence to obtain a ceramic plate with a thickness of D2mm. Among them, the thickness processing amount of flat grinding is 0.05mm (ie: reduce the thickness by 0.05mm), and the thickness processing amount of rough polishing is 0.05mm (ie: reduce the thickness by 0.05mm).

[0067] (2) Place the ceramic plate in the hot bending mold, raise the temperature to T2°C at a rate of V1°C / min, and apply a pre-bending pressure of P1N to the ceramic plate at T2°C to pre-bend the ceramic plate for t2h to obtain...

Embodiment 15

[0076] The preparation process of the shell of this embodiment is substantially the same as that of Embodiment 5, except that in step (4), the bent ceramic plate is directly cooled with the furnace to obtain a cooled ceramic material.

Abstract

The invention relates to a shell, its preparation method and electronic equipment. The preparation method of the shell includes the following steps: placing the ceramic plate in a hot bending mold, and performing pre-bending at 1000°C to 1200°C; The final ceramic plate is hot-bent to obtain the shell. The above method for preparing the casing can obtain a casing with better mechanical properties while reducing the machining allowance.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a shell, its preparation method and electronic equipment. Background technique [0002] Generally, the preparation process of the shell of electronic equipment includes the following steps: mixing ceramic powder and organic matter, and then molding to obtain a shell-shaped green body, and then sintering the shell-shaped green body to obtain a blank with a certain shape and size, and the blank is processed A shell of final shape and size is obtained. In the above preparation process, in order to ensure the strength of the shell-shaped material in each process (molding, sintering and blank processing), the shell-shaped material in each process needs to have a certain thickness, resulting in a large machining allowance for the blank. Therefore, in the above-mentioned process of preparing the shell by sintering the shell-shaped green body, the machining allowance of the blank is ...
