The application of MIM injection molding technology in mobile phone industry

Writer： Admin Source： MDM Date：2024-03-06

Metal injection Molding (< Injection Molding, MIM) is a near-net molding process suitable for producing small,
three-dimensional complex shapes and products with special property requirements. MIM is developed from the
fusion of traditional powder metallurgy process and modern plastic injection Molding technology, metal injection
Molding -MIM combines two well-known production technologies (injection molding technology and sintering
technology).
MIM technology is an innovative process for the production of complex metal series components. The recent
investment boom in the industry is due to the wide application of MIM parts in the mobile phone industry, such as
mobile phone keys, SIM cards, card slots, lens rings, LED rings, rotating shafts, etc.
The application of MIM injection molding technology in digital electronics, in recent years, we are more familiar
with, should be mobile phones and laptops, such as mobile phone metal cato, volume buttons, mobile phone
interfaces, camera frames, shaft hinges, lifting camera precision parts, double and triple camera precision parts,
laptop shaft, gear and so on.
The specific application of MIM injection molding technology in the mobile phone industry is reflected in the
following places.
1. Mobile phone camera holder
The mobile phone camera bracket is relatively small, the structure is more precise, the performance requirements
are better, the ordinary production process is difficult to produce, and the production cost is high.
MIM injection molding can form a variety of precision metal parts at one time, fewer processing steps, fast
molding, high material utilization, and mass production, which is a very efficient molding technology for the
production of mobile phone camera brackets.
2, folding screen rotating shaft
The middle core component of the folding screen rotating shaft needs to have the advantages of light weight,
flexibility, thin shape and stability. MIM injection molding technology ensures accuracy, strength and stability.
3. Mobile phone card
Mobile phone Cato materials need to have structural density, wear resistance and other performance advantages,
Mim injection molding is agreed to be a very suitable for the production of mobile phone Cato molding technology.
4, mobile phone lifting camera
Most of the miniature precision parts inside the camera screw rod, slide rail, etc., are produced by MIM injection
molding, which can be mass-produced and ensure the high quality of precision parts, and its production cost is
lower than that of traditional processes.
