The accuracy tolerance must be within 5H. Each shell includes a mixture of blind holes and through holes with a hole depth between 1 to 2 x D. A total of 28 holes in various diameters are required to be made per part. The tablet computer shells are made of AL6R01 aluminum (equivalent to A6061 aluminum). Right: An image of a tablet computer shell made of AL6R01 aluminum (equivalent to A6061 aluminum). Left: Inside the production site of the tablet computer shell manufacturer in Dongguan, Guangdong, China. Currently, this company has more than 10,000 employees in its two production facilities and its main plant is more than 43,000-square-meter in size. Recently, a part manufacturer of 3C appliances located in Dongguan, Guangdong, China, whose name cannot be disclosed due to confidentiality reasons, was seeking for an improved threading solution for its trial production of tablet computer shells.Įstablished in 2010, this company specializes in part production of information appliances, mainly producing the metal parts of intelligent terminals and related accessories. Therefore, rather than thread cutting, OSG recommends thread forming for small diameter tapping in 3C applications. As opposed to cutting taps, thread forming tools can offer advantages such as long tool life and high process reliability because a forming tap forms screw threads through plastic deformation of work material with no cutting chips created. Breakage can easily occur due to the small size of the tap diameter. M0.8 x 0.2 (special), M1 x 0.25, M1.2 x 0.2, M1.6 x 0.35 and M2 x 0.4 are some of the most common tap sizes for small diameter machining. However, small diameter tapping is a challenging machining process in these two types of aluminum. The use of AL6 and AL7 aluminum (equivalent to A60 and A70 series aluminum) in China’s 3C product shell market has drastically increased in recent years. With reduced weight and material, the size of screws has also become smaller. Information appliances today are ultra-thin and lightweight. With rapid advancement in information technologies, 3C products – the combination of computers, communications, and consumer electronics, have become highly popular due to their superior portability and personalization ability.
