Did you find the MIM part hidden in the new 5G mobile phone?

2019 is just over. Looking back at the mobile phone circle of the past year, 5G is undoubtedly an unavoidable topic.
Recently, Deloitte ’s Connectivity and Mobile Trends Report revealed that 67% of surveyed users indicated that they would choose to purchase mobile phones compatible with 5G networks, and 16% of surveyed users indicated that the next mobile phone would choose a 5G-enabled mobile . With such a strong will, consumers will inevitably set off a wave of 5G replacements.

On December 26th, OPPO released the Reno3 series in Hangzhou. Both models support dual-mode 5G networks, and are equipped with video super dual anti-shake functions, focusing on video applications in 5G environments.
In addition to OPPO, major mobile phone application manufacturers at home and abroad also launched corresponding products for the 5G market. In 2020, 5G applications will usher in rapid development next year, and relevant agencies predict that 5G smartphone shipments will reach 300 million units next year.

With the development of the 3C electronics industry, many supporting industries will also usher in unlimited industry opportunities. Among them, MIM, as "the most popular part forming technology today", is mainly used in smart phone card holder, camera ring metal protection frame, connection The components such as the device interface also provide "elevating camera" components for many smart phones in 2019.

Behind the brilliance of 5G mobile phones is MIM's "pay"
MIM (l Injection Molding), that is, metal powder injection molding, is suitable for mass production of small, precise, complex three-dimensional shapes and metal parts with special performance requirements.
In China, 3C products are the largest field of MIM applications, and the rapid development of the mobile phone, communications, and optical fiber industries has brought huge opportunities to the MIM industry. The parts in the 3C industry require high precision and durability, which are in line with the characteristics of MIM products. They are often used to make mobile phone trays, card slots, structural parts, connectors, shaped parts, vibrators and other products.
Don't know much about this process? It doesn't matter, I'll talk to you immediately!
MIM is a molding method that injects a plasticized mixture of metal powder and its binder into the model, and has a high technical content. To put it simply, MIM is to mix metal powder and binder uniformly, and process it into metal devices of various shapes.

The finished product made by MIM has high density, high precision and excellent surface finish. If you do n’t believe it, you can press the Cato out of your phone to see if it ’s very mini, very delicate, and do n’t get stuck
Compared with other processes, what are the advantages of MIM?
MIM technology combines the advantages of powder metallurgy and plastic injection molding technology, breaking through the limitations of traditional metal powder molding process in product shape, while using plastic injection molding technology to form large-volume, high-efficiency parts with complex shapes It has become a near-net-shaping technology for modern manufacturing high-quality precision parts, and has advantages that conventional powder metallurgy, machining and precision casting methods cannot match.
First of all, before the maturity of MIM technology, there is a traditional powder metallurgy method-PM. Its metal powder is usually 50-100 microns, which is much larger than MIM 0.5-20 microns powder particles. Therefore, for small parts that require high accuracy and freedom of shape, traditional technology is powerless.
Secondly, there is the traditional machining method-CNC. MIM and CNC, one is "plus" and the other is "minus", two different technical languages, allowing them to excel in different worlds. For example, it ’s like giving you a big stone and carving a statue. That should be fine, but letting you carve a toothpick ... Do you think this cost is too high?
Therefore, the MIM process occupies a natural advantage for parts with ultra-small dimensions and complex three-dimensional structures. （Reprint）
