Metal Injection Molding Titanium Alloy Mobile Phone MIM Parts

How Many MIM Parts Are There In Mobile Phones?

Mobile phones are indispensable equipment for everyone. With the development of communication technology from 3G to 4G, and now to 5G, the form of mobile phones is constantly changing. Driven by the rapid development of the mobile phone industry, metal powder injection molding (MIM) has also taken advantage of the opportunity to gain huge opportunities.

Which Mobile Phone Parts Will Require OurMIM?

The application of MIM technology in mobile phones, currently everyone is more familiar with mobile phone metal card trays, volume buttons, mobile phone interfaces, camera frames, hinges, lifting camera precision parts, dual-camera and triple-camera precision parts, gears, etc.

1. Mobile phone camera bracket

The camera function is essential for every mobile phone, but there are relatively few mobile phone camera brackets, the structure is more precise, and the performance requirements are relatively good. Ordinary production processes are difficult to produce and the production cost is high. MIM can form various precision metal parts at one time, with fewer processing steps, fast forming, high material utilization rate, and can be mass-produced. The production of mobile phone camera brackets is very efficient.

The large number of mobile phone lenses means that the lenses, sensors, LED flash and other components must be firmly and safely assembled together to make the bracket of the camera ring thinner. However, to meet these requirements, the wall thickness, flatness and contour of the product must also be improved, and all this is due to MIM powder metallurgy technology.

2. Folding screen shaft

The core of folding mobile phones is the shaft at the folding point of the two screens of the mobile phone. It almost determines the success or failure of the folding screen. In addition to the foldable and thin design, the middle core component shaft also needs to be light, flexible, thin and reliable. The requirements for rotation accuracy and friction coefficient are particularly high. Therefore, MIM injection molding technology is very suitable and can ensure stability and strength.

3. Mobile phone card tray

Since the mobile phone has changed from a removable battery to the current non-removable structural design, there is an additional design on the mobile phone: SIM card tray. In order to make the card tray automatically pop up under the elastic action of the pop-up mechanism and save space and achieve a sufficiently beautiful effect, the production precision of the mobile phone card tray is very high, and it also needs to have performance advantages such as density, structural density, and wear resistance. MIM injection molding is unanimously considered to be a very suitable molding technology for the production of mobile phone card trays.

4. Mobile phone lifting camera

In recent years, users' pursuit of screen ratio has reached its peak, so designers have tried their best to break through our requirements to achieve 100% full screen. However, a solution was designed, which is the lifting camera we know. While solving the problem of the screen's beauty, the mechanical control of one rise and one fall is full of technology.

In order to realize the camera lifting function, the camera needs the support of micro-precision parts such as spiral 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 the high quality of precision parts, and the production cost is lower than that of traditional processes.

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. has relevant technical reserves and accumulation for the application of titanium alloy materials in MIM technology, but the specific application still depends on customer needs.

Zhongwei Precision Company mainly provides large quantities of customized MIM core components with high complexity, high precision, high strength and exquisite appearance for consumer electronics fields such as smartphones, wearable devices, notebooks and tablets, as well as automotive fields. Its products cover multiple subcategories such as mobile phone card trays, camera decorative rings, buttons, wearable device cases, watch buckles, notebook cooling fans, automotive parts, etc.
