Parmatech, California, was invented in 1973. In the early 1980s, many countries in Europe and Japan also invested a lot of energy to start researching the technology and quickly promote it. Especially in the mid-1980s, this technology has achieved rapid development since it was industrialized, and it is increasing at an alarming rate every year. So far, more than 100 companies in more than ten countries and regions such as the United States, Western Europe and Japan are engaged in the product development, research and sales of the process technology. Japan is very active in competition and has outstanding performance. Many large companies are involved in the promotion of MIM industry, including Pacific Metal, Mitsubishi Steel, Kawasaki Steel, Kobe Steel, Sumitomo Mine, Seiko-Epson, Datong Special steel, etc. At present, there are more than forty companies specializing in the MIM industry in Japan, and the total sales value of MIM industrial products has already surpassed that of Europe and directly pursued the United States. So far, more than 100 companies around the world have been engaged in the product development, research and sales of this technology. MIM technology has thus become the most active frontier technology field in the new manufacturing industry, and is represented by the pioneering technology of the world metallurgical industry. The main direction of powder metallurgy technology development MIM technology.
