The reason why MIM is favored by the mobile phone industry depends entirely on its own ability. In fact, before the maturity of MIM technology, there is still a traditional powder metallurgy method - PM. Its metal powder is usually 50-100 microns, which is much larger than the powder particles of MIM 1-20 microns. Therefore, for small parts that require high precision and shape freedom, traditional technology is powerless.

Technically, MIM combines the advantages of powder metallurgy and plastic injection molding, breaking through the limitations of traditional metal powder molding technology on product shape, and also has plastic injection molding technology, which can form large-scale, high-efficiency and complex Therefore, it is possible to mass-produce small, precise, complex three-dimensional shapes and metal parts with special performance requirements - this is in line with the requirements of the 3C industry.

Mobile phone lift camera

In recent years, users' pursuit of the screen ratio of mobile phones has reached an unprecedented level, so designers have tried their best to pursue breakthroughs. In order to move closer to a 100% full screen, a solution has been designed, that is, a lift camera. While solving the aesthetic problem of the screen, the mechanical control of "one lift and one drop" is also full of technological sense.

In order to realize the lifting function of the camera, the camera needs to be supported by micro precision parts such as screw rods and slide rails, and these parts need to be produced by MIM injection molding, which can not only be mass-produced, but also ensure high precision parts. quality, and the production cost is lower than that of traditional processes.

In the past few years, the MIM injection molding industry has been very stable in the shipment of precision parts such as dual-camera, triple-camera, and mobile phone card trays. While maintaining a stable foundation, accessories such as the hinge hinge, the core part of the folding screen, also allow MIM to continue to have new products. market opportunities.

At present, with the advantages of near net shape, almost no waste, and mass production, MIM is currently being recognized and applied in the mobile phone industry. The penetration rate of the field will also continue to increase, and the relevant market is very worth looking forward to!
