MIM process MIM process is a manufacturing technology that combines metal powder injection molding and plastic injection molding. Its basic principle is to mix metal powder and binder to make metal injection molding blanks, then use plastic injection molding machine to inject the blanks, and finally obtain the final product through degreasing and sintering.
MIM process is widely used in the manufacture of 3C electronic products
Manufacturing of mobile phone shells Mobile phone shells are an important part of mobile phones. MIM process can produce high-precision, high-strength and lightweight mobile phone shells. During the manufacturing process, the MIM process is first used to manufacture the injection molding blanks of the mobile phone shells, and then the blanks are placed in the mold for injection molding, and finally surface treatment and assembly are performed.
Camera manufacturing The manufacturing of mobile phone cameras requires high precision and miniaturization. MIM process can manufacture high-precision miniaturized lenses and brackets. During the production process, the MIM process is first used to manufacture the injection molding blanks of the camera bracket and lens, and then the blanks are placed in the mold for injection molding, and finally surface treatment and assembly are performed.
Manufacturing of card trays Card trays are an important part of mobile electronic products. MIM technology can produce card trays with high precision, high strength and light weight. In the manufacturing process, the MIM process is first used to manufacture the injection molding blanks of the card trays, and then the blanks are placed in the card tray mold for injection molding, and finally surface treatment and assembly are performed.
Manufacturing of hinges Folding mobile phones are also a kind of electronic products. The hinges of its folding screen can also be manufactured using the MIM process. Some of the very precise parts require the use of the MIM process, and the MIM process accuracy can reach ±0.1%~±0.3%
Manufacturing of buttons The buttons next to smart watches are also used for 3C electronic products, such as the buttons below, which are also manufactured using the MIM process.
Manufacturing of capacitive pen caps The parts used in the capacitive pen equipped with iPad are also made using the MIM process.
Manufacturing of smart watch straps Smart watch straps are a kind of 3C electronic products, such as the following chart straps. The MIM process can manufacture smart watch straps with high precision. And through subsequent processing, exquisite products can be obtained.
In 2010, the MIM process technology was used in the label appearance parts of BlackBerry mobile phones, which opened the way for the mass use of MIM parts in mobile phones; in 2012, MIM assemblies were used for the first time in tablet computers, breaking the use of single parts of MIM products. Apple has been using MIM parts since 2010, and has continuously expanded and led the use of MIM. The successful application of MIM parts such as power interface parts, card trays, camera rings, and buttons in mobile phones has made Chinese MIM companies a leader in the field of consumer electronics. As consumer electronic products such as smart phones and smart wearable devices develop towards lighter and thinner products, the core components of these products will also become more sophisticated and complex. In this context, the application prospects of MIM technology will become increasingly broad.
