Year 2018 is not only the diversification of mobile phone screen, but also the innovation history of mobile camera. Mobile phone market positioning gradually closes to camera. The development of multi-camera is gradually expanding. Following three cameras of Huawei P20 Pro,OPPO R17Pro, Huawei launched the three camera- four lens- Huawei Mate 20 series.

Huawei Mate 20 series three camera- four lens adopt matrix multifocal image system, derives from "the eye of supercar", this design pioneered the arrangement of cameras. It looks like a simple arrangement, but has very high requirements for industrial design, stack architecture, technology. Huawei Mate 20's three camera- four lens structure guide the development trend of camera structure, meanwhile bringing opportunities and innovation to metal injection molding industry once again.


Mobile phones moves to multiple lens modules, bringing together the lenses, sensors, LED flash and other components firmly and safely are benefit from its camera bracket which made by metal injection molding MIM process. Multi-lens means that the frame of the camera ring becomes thinner and more complicated, and claims higher requirement on product’s thickness, flatness and profile. However, MIM metal injection molding has unique advantages in machining parts with complex geometry, uniform structure and excellent performance.


Metal injection Molding (MIM) is a kind of near-net environmental protection forming process, which uses metal powder (such as SUS316L,P.A.N.A.C.E.A) as raw material and adopts "injection+sintering" process, to produce complex parts at low cost.


Process of producing multi-lens bracket : feedstock preparation, injection, debinding and sintering, secondary process, CNC, demagnetization, PVD, inspection, packaging and so on. Metal injection molding process is the core process.



Feedstock preparation:


Mixing metal powder and plastic binder firstly, then granulate it through extrusion equipment to get feedstock. As the core part of feedstock, plastic binder affects feedstock’s uniformity and formability directly. And then affect the follow-up process and performance of final product.


Injection process:


Heating the material to its melting temperature, injection the solution to cavity through increasing pressure, after cool down in cavity, product shape finished.


Debinding process:


The binder is mainly composed of POM (polyformaldehyde), and a small amount of HDPE (high density polyethylene), EVA (ethylene-vinyl acetate copolymer) and PW (paraffin) and so on.


Debinding refers to remove the polyformaldehyde (or paraffin) from green parts to prevent the binder from gasification during sintering to cause quality problems like bubbling and boring. It is a preparation for the sintering process.


Sintering process:


Sintering is the last step in metal injection molding MIM process. It eliminates pores between powder particles in order to achieve full density or near-complete densification of MIM products, In design stage, it is necessary to take deformation and dimensional accuracy on full consideration.


Another advantage of multi-camera bracket choosing metal injection molding MIM process is that it can mass producing with high efficiency.


Huawei P20/Pro was popular when it was launched, sales exceeded 6 million in three months, and MIM parts can be offered 500000 units per day in short term, which is unable to be achieved by other processing. Huawei estimate sales Mate 20 series 20 million units, which will be a boon for metal injection molding industry.


According to the direction of current mobile phone lens, the future mobile phone may be like this-"all screen in front, all camera in back "! Metal injection molding (MIM), as one of the important precision process, plays an important role in the development of camera bracket. As a gold digger for MIM processing in 3C industry (SIM card tray, camera bracket, IO, etc.), iphone will also apply matrix camera in its next-generation.


MIM industry continued to thrive in 2018, with the camera bracket replacing SIM card tray to be the star product, same in MIM industry, MIM also have two kinds of materials popular particularly : BASF's p.a.n.a.c.e.a and F75.
