Problems solved by technology

[0003] The speaker hole on the metal shell is usually machined by CNC, but during processing, because the thickness of the metal shell is relatively thick, and the tool is too small, it is easy to break the knife, and the processing time is long and the cost increases
In addition, the diameter of the processed speaker hole is generally about 0.5 ~ 1.0mm. This size of hole has the hidden danger of water and sundries, and sharp objects such as toothpicks and needles may pierce the internal components through the hole.

Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The metal casing referred to in the present invention can be the metal casing of various electronic devices such as mobile phone, tablet computer, laptop computer, etc., for the convenience of description, in the following description, the metal casing of mobile phone is used as an example to illustrate, and for The same symbols are used for the same components.

[0024] figure 2 It is a schematic diagram showing a part of the flow of the metal casing manufacturing method of the present invention.

[0025] When making a metal case for a mobile phone, it is first necessary to prepare a metal plate of a predetermined size.

[0026] Then, the sheet metal is processed into a metal shell having a predetermined shape by stamping and forging and CNC processing or only by CNC processing, such as figure 2 Step (A).

[0027] Then, in the predetermined area of ​​the ...

Abstract

The invention provides a manufacturing method for a metal shell body, the metal shell body and electronic equipment using the metal shell body. The manufacturing method for the metal shell body comprises the steps that the preparation working procedure is conducted, specifically, a metal board with the predetermined size is prepared; the forming working procedure is conducted, specifically, the metal board is machined to be the metal shell body with a predetermined shape; the thinning working procedure is conducted, specifically, in the predetermined area of the metal shell body, the metal shell body is subjected to thinning machining; and the hole-through working procedure is conducted, specifically, micro pores or micro cracks are formed in the predetermined area.

Description

technical field [0001] The invention relates to a manufacturing technology of a metal casing, in particular to a manufacturing technology of a metal casing of electronic equipment such as a mobile phone, a tablet computer, and a laptop computer. Background technique [0002] Electronic devices such as mobile phones, tablet computers, and laptop computers often use metal casings, and there are speaker holes 1 on the metal casings, such as figure 1 shown. [0003] The speaker hole on the metal shell is usually machined by CNC, but during processing, because the thickness of the metal shell is relatively thick, and the cutting tool is too small, it is easy to break the knife, and the processing time is long and the cost increases. In addition, the diameter of the processed speaker hole is generally about 0.5 ~ 1.0mm. This size of hole has the hidden danger of water and sundries, and sharp objects such as toothpicks and needles may pierce the internal components through the hol...
