Mobile phone lift camera
In recent years, users' pursuit of mobile phone screen ratio has reached an unprecedented level, so designers have tried their best to find breakthroughs. In order to move closer to a 100% full screen, a solution was designed, that is, a lifting camera. While solving the aesthetic problem of the screen, the mechanical control of "one up and one down" is also full of sense of technology.
In order to realize the lifting function of the Mobile phone camera circle MIM Parts, the inside of 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 be mass-produced and Ensure the high quality of precision parts, and lower production costs than traditional processes.
At present, full-screen mobile phones have become a must-have feature for high-end phones and thousand-dollar smartphones. This year, not only are major mobile phone manufacturers competing in smart phones, but mobile phone cameras are also constantly innovating, and mobile phone cameras have begun to become multi-functional and professional. , dual-camera, triple-camera, and quad-camera are slowly being applied to smartphones, especially the Huawei Mate20 series, which has three cameras and four holes, creating a precedent for smartphones, and the innovative spirit is worth remembering.
The three-camera four-hole Yuba of the Huawei Mate 20 series adopts a matrix multi-focus imaging system, which is derived from the "eyes of supercars". This design has created a precedent for camera arrangement. On the surface, it is a simple arrangement, but it has extremely high requirements for industrial design, stacking architecture, and technology. The three-camera and four-hole Yuba structure of Huawei Mate 20 guides the development trend of the camera structure, and the MIM industry once again ushers in opportunities and innovations
The mobile phone is going towards the multi-lens module, which integrates the lens, sensor, LED flash and other components together firmly and safely, thanks to the camera bracket processed by MIM. The multi-camera lens means that the bracket of the camera ring becomes thinner, the shape is more complex, and the product has higher requirements for wall thickness, flatness, and contour. MIM has unique advantages in processing near-net-shape parts with complex geometric shapes, uniform structure, and excellent performance.
What is Powder Metallurgy Injection Molding (MIM)?
Powder injection molding (MIM) uses metal powder as raw material and adopts "forming + sintering". It is known as a near-net environmental protection forming process for producing complex parts at a lower cost.
What are the advantages of MIM powder injection molding technology?
1: Provide solutions to solve complex three-dimensional shape requirements
The process uses the principle of injection molding to manufacture metal products of complex shapes.
2: Highly efficient production capacity
The process mold can be designed as one mold with multiple cavities, fully automatic production, which can meet the production capacity requirements of precision metal parts with large demand.
3: Good surface and mechanical properties
Due to its high density, this process can reach more than 95% of the theoretical density, which can meet the performance requirements of high strength, high toughness, high hardness, and high wear resistance of the product, and the surface can be mirror polished.
4: Extensive application
This process is widely used in consumer electronics, auto parts, medical equipment, optical communications, locks and other fields.
According to the current development direction of the mobile phone circle, the future mobile phone may be like this - "the front is full of screens, and the back is full of cameras"! Metal powder injection molding (MIM), as one of the forming processes of important precision parts, plays an important role in the development and changes of camera brackets. Apple, as a gold digger in MIM processing in the 3C industry (cato, camera bracket, IO, etc.), will also have a matrix camera in the next generation of iPhone.
