Among the many mobile phone body materials, metal should be the most flattering. The unique luster and touch of metal can improve the product quality, but because of its high manufacturing process and cost, there are few mobile phones in the past. Will use a full metal body. The metal body is not only the difficulty of the simple processing technology, but also takes into account the performance of all aspects, the signal is not affected, the parts are easy to install, the rigorous, the external force impact deformation and many other problems. Especially in the handling of the antenna, even the apples that have always had a high level of manufacturing technology have suffered losses on the iPhone 4. However, with the continuous improvement of the entire industry level, there are more and more mobile phones with all-metal body design. China's super-hard material network Xiaobian will take you to understand the processing technology of all-metal body phone.

Compared with injection-molded plastic mobile phones, the metal material Unibody shell is much more complicated. The first thing you need is a CNC machine (computer numerical control machine). CNC machine is a program-controlled automated machine tool that can logically process a program with control code or other symbolic instructions and decode it through a computer, so that the machine performs the specified action through tool cutting. The blank material is processed into semi-finished finished parts, and the machining cost of the CNC machine tool is determined by the size, complexity and machining accuracy of the workpiece.
In the beginning, the outer casing of the mobile phone was just a silver rectangular aluminum plate. The general shape of the inner side of the outer casing was milled on the machine tool. At this point we can see the rounded corner of the outer casing, but there are two protrusions in the middle of the aluminum plate. This is used in the subsequent processing of fixing the aluminum plate and ensuring the strength of the aluminum plate.
The aluminum plate is then subjected to horizontal and vertical milling on the milling machine, and the excess aluminum alloy is removed to depict the arc of the outer casing.
After this step is completed, place the outer casing on a PVC or paraffin fixture, use a small cutter head to engrave the decorative strips on the upper and lower parts of the outer casing, and trim the burrs, then mill the edges of the outer casing out of the sparkling chamfer. .
The front aluminum panel, which is being punched in the picture, is the result of the dense speaker hole on the speaker.
