Stainless steel is everywhere in 3C electronic products

Traditional consumer electronic products usually include smartphones, tablets, laptops, digital cameras and other hardware devices, while emerging consumer electronic devices include smart wearable devices, drones and so on. In 2010, the label appearance of BlackBerry phones adopted MIM process technology, opening up the mass use of MIM parts on mobile phones; in 2012, MIM composite parts were used on tablets for the first time, breaking the single-part use mode 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, buttons and so on on mobile phones has achieved the leading position of Chinese MIM enterprises in the field of consumer electronics. With the development of consumer electronic products such as smartphones and smart wearable devices to be more lightweight, the core parts of these products will also become more precise and complex. In this context, the application prospects of MIM technology will be increasingly broad.

All the electronic products in the above picture need various stainless steel (or titanium alloy, pure copper) metal accessories; take our commonly used mobile phone as an example, the parts that contain stainless steel material and need to use powder metallurgy MIM technology to complete are: power button, mute button, SIM card tray, volume up and down button, 8PIN data cable socket, built-in vibration motor rotor, built-in N41 pad foot and so on. The earphone contains parts such as hinge shaft hinge, earphone hinge, built-in structure parts and so on.

The same application products also include:

The stainless steel material of powder metallurgy MIM technology has better strength and density than other materials. It can greatly reduce the resonance generated by the device in the sound frequency surface and restore the low, medium and high three frequencies more accurately. Especially in the high frequency part of the performance ability is very outstanding. It has excellent transparency and can create a more distinctive sound quality. Most of them have high fidelity.

Secondly, the production cycle of stainless steel accessories is short. It does not need to open mold and spend a lot of time and money. The stainless steel quality was general and expensive in the past. In recent years, stainless steel products produced by powder metallurgy MIM have been mass-produced. The price of stainless steel has decreased; at the same time, the development of technology has also made stainless steel products more diversified and better in quality. Due to the continuous improvement of production efficiency and quality improvement. Stainless steel material in injection molding (MIM) has become one of the most cost-effective technologies and one of the most important building materials in the world.

At the same time, stainless steel electronic product shell has excellent performance. It has good corrosion resistance and heat resistance. The corrosion resistance performance of powder metallurgy MIM technology is much better than other materials. It is not easy to corrode in humid environment. Heat resistance performance is also very good. It will heat up during use but will not affect use due to temperature rise.
