Explore iphone6S mobile phone body surface treatment process

The alloys selected for the iPhone 6s are the same grades as the materials used in the aerospace industry. This aluminum metal uses a unique elemental composition that is more robust than the materials used in the previous iPhone body. 7000 series aluminum metal, externally stronger. Before we talk about the surface treatment process, let us take a look at the materials and advantages of the 7000 series aluminum alloy:
1, 7000 series aluminum alloy mainly contains zinc. It belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy. It is a heat treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance.
2, 7000 series aluminum plate is stress-relieved, will not deform and warp after processing. All the ultra-thick and thick 7 series aluminum plates are all ultrasonically detected, which can guarantee no blisters and impurities.
3, 7000 series aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is the high hardness. Take the 7075 as an example. It is a high hardness, high strength aluminum alloy, which is often used to manufacture aircraft structures and futures. It requires high-strength structural parts with high strength and corrosion resistance, and mold manufacturing. The new iPhone 6s and iPhone 6s Plus from Apple not only retain the excitement of the previous generation, but also have new breakthroughs this time. They are made from 7000 series aluminum metal, making them stronger than ever. So how do we achieve the ultimate in the 7000 series of aluminum alloys in its surface treatment?

First, from the profile / forging stamping, and then the CNC workpiece milling, and then through the automated secondary processing, to the surface treatment, and finally the finished product. Each of these processes seems simple, but because of the strong hardness of the 7000 series aluminum alloy, it is crucial to choose each of the consumables. Apple has carefully designed all aspects of the iPhone 6s, and even each of its processing techniques has been carefully matched. The requirements for deburring, anode, rough throwing, fine polishing and other aspects are quite strict. The following is a typical mobile phone surface treatment process flow chart.
