Metal injection molding (MIM) is a molding method in which the plasticized mixture of metal powder and its binder is injected into the model. Firstly, the selected powder is mixed with the binder, then the mixture is granulated, and then the shape required by injection molding is formed. The polymer imparts the characteristics of its viscous flow to the mixture, which contributes to the uniformity of forming, cavity filling and powder filling. After forming, remove the binder, and then sinter the degreased blank. Some sintered products may need further densification treatment, heat treatment or machining. Sintered products not only have the same complex shape and high precision as those obtained by plastic injection molding, but also have physical, chemical and mechanical properties close to those of forgings. The process technology is suitable for mass production of small, precise, three-dimensional complex metal parts with special performance requirements. MIM is known as "one of the hottest metal parts forming technologies in the world". It has become a new near net shape technology with rapid development and the most promising in the field of international powder metallurgy. MIM process has extremely high barriers and has great advantages in the production of complex metal products. MIM has a wide range of applications. Globally, MIM technology has been widely used in many fields, such as automobiles, electronic products, medical devices, consumer goods and so on.

In the field of consumer electronics, MIM technology is widely used to provide customized MIM core parts products with high complexity, high precision, high strength and exquisite appearance for consumer electronics fields such as smart phones and wearable devices and automotive fields. The products cover multiple sub categories such as camera brackets, connector interfaces, decorative rings, mobile phone rotating shaft parts, wearable structural parts and so on.
