In 1988, the world powder metallurgy convention, in Florida of the United States, first unveiled the technology for the injection of metal powder, attracting experts and scholars from around the globe. In the same year, the parent company, China steel research institute, the former metallurgical research and steel research institute began to develop the process. At the end of the 1990s, the most familiar MIM application was the tungsten alloy oscillator of the vibrating motor of the BP machine. Since 2000, the series of stainless steel series has been widely used, such as the fiber connector, the consumer electronics series of hinge series, the mobile phone buttons, the sim card slot and so on. Recently MIM industry investment boom, is due to the MIM parts are widely used in mobile phone industry, as well as 3C industry assembly plant in China, the investment threshold is reduced, it attracted a lot of capital inflows.
The development of metal powder injection was developed by the powder metallurgy industry, and the technology was more mature and stable. Metallurgical and metal powder injection molding technology mainly includes the following aspects: the preparation of feedstock, injection molding, injection molding process of computer simulation, degreasing, sintering, the application of MIM, MIM products design and specification.
China has become the world’s largest auto producer. Along with the development of the automobile industry, the auto parts market will also develop rapidly. The number of MIM products used in every car in the world is 14kg in Europe, 16kg in Japan and 19.5kg in the US. Domestic car MIM USES only about 5 kilograms. This also bodes well for the potential of the MIM parts product market in the next few years. The MIM companies will seize this opportunity to raise the level of technology and meet even greater challenges.
