Metal injection molding can be traced back to the preparation of powder injection molding for ceramic spark plugs starting in the 1920s. In the following decades, powder injection molding was mainly concentrated in ceramic injection molding. It was not until 1979 that Parmatech, a company formed by Wiech and others, won two awards for metal injection molding products, and Wiech and Rivers received patents at that time. Powder injection molding began to shift to metal injection molding as the dominant one. After Parmatech transferred several of their patents, MIM companies were established one after another. In 1980 Wiech formed Witec, and in 1982 Brunswick entered the MIM industry and acquired Witec. Subsidiaries such as Omark Industries, Remington Military Products, and Rocky Dental were gradually registered. In 1986, Nippon Seison of Japan introduced the Wiech process. In 1990, the Israeli Metalor 2000 company Parmatech introduced Wiech process technology and established the MIM production line. After nearly two decades of development, the total value of the global MIM product market reached about 1 billion US dollars in 2003. The United States accounted for 55% by region, followed by Europe and Japan. At present, there are more than 500 companies engaged in the production and sales of metal injection molding products around the world, in addition to about 40 MIM powder suppliers and 20 MIM feed suppliers. According to statistics, the global MIM industry has a molding capacity of more than 700 injection molding machines, 500 furnaces, and 300 mixers. Marko Maetzig analyzed the situation in Europe in detail. There are 120 companies and 30 research institutions engaged in MIM work in Europe, with 250 injection molding machines and an annual consumption of 1100 tons of feed. 38% of European MIM companies are from the traditional ceramic industry, 27% are from the plastics industry, 8% are from the traditional powder metallurgy and metal cutting industries, 5% are from the foundry industry, and 14% are newly established companies. There are now 20 to 30 MIM companies in Japan, and the MIM market in Japan has shown a steady upward trend in recent years. Although there was a decrease in 2001 compared to 2000, overall, its total sales showed a steady growth trend.    

MIM has experienced a rapid development path. Although MIM is attracting more and more attention, its industrial scale is still weak compared with traditional processing technology, and there is still great potential for development. The new MIM industry also requires us to take a series of efforts such as formulating industrial standards, accelerating industrialization, improving the quality of practitioners, developing equipment, and winning customers to develop and grow it. With the continuous improvement of the process, the superiority of metal injection molding technology is gradually showing, and it will be accepted by more and more industries and customers, and the market share it brings is also increasing sharply. Due to the huge market potential, many venture capitalists have also begun to get involved in the MIM industry. It is foreseeable that MIM will develop into one of the most promising parts manufacturing technologies in the 21st century.
