Introduction to Powder Metallurgy MIM Injection Molding

Metal powder injection molding (MIM) is a molding method that injects a plasticized mixture of metal powder and its binder into a model. It first mixes the selected powder with the binder, then granulates the mixture and injects it into the desired shape. MIM technology, as a near net forming technology for manufacturing high-quality precision parts, has advantages that conventional powder metallurgy, machining, and precision casting methods cannot match.

Equipment required for MIM injection molding: granulation integrated machine, MIM specialized injection molding machine, degreasing furnace, sintering furnace, testing equipment, secondary processing equipment, etc.

MIM technology is mainly applied in fields such as consumer electronics, automotive parts, medical devices, hardware tools, etc. According to statistical data from the Powder Metallurgy Branch of the China Steel Structure Association, the global MIM market size reached 2.283 billion US dollars in 2016, while the domestic MIM market size increased from 1.35 billion in 2012 to nearly 6 billion US dollars. Below is a specific introduction to the application of MIM injection molding technology in the field of automotive components.

From the perspective of the application field of automotive components, automotive components are the largest application field of traditional powder metallurgy technology. Based on the advantages of excellent performance, low cost, and light weight of MIM technology, it has gradually replaced traditional powder metallurgy technology and is used in complex shaped parts such as turbocharged parts, ignition switches, reverse gears, convertible top components, and power steering components. It is expected to expand its application to more categories in the future.

Finally, the development of MIM process technology in China started relatively late, but the industry has a strong momentum of development. The Pearl River Delta MIM factory is the most concentrated region in the global MIM industry, with nearly 100 processing factories, mainly concentrated in areas such as Shenzhen, Dongguan, and Huizhou. With the development of the market, the concentration of competition pattern is also inevitable. In the environment of rapid market changes and technological breakthroughs, it is particularly important to seize market opportunities.
