Best describes the importance of the MIM process in the direction of powder metallurgy technology

time:2020-05-27Views:176 Author:Best Seiko

Metal Powder Injection Molding (MetalPowderInjectionMolding, referred to as MIM) is a new type of powder metallurgy near net forming technology that is formed by introducing modern plastic injection molding technology into the field of powder metallurgy. The basic process is as follows: 1. Mix the solid powder with the organic binder evenly, and after granulation, use the injection molding machine to inject into the mold cavity to solidify and shape under the heating and plasticizing state (~150℃); 2. Then use chemical Or thermal decomposition method to remove the binder in the forming blank; 3. Then sintering and densification to obtain the product. Compared with traditional processes, MIM factory technology has the characteristics of high precision, uniform organization, excellent performance, and low production cost. Its products are widely used in electronic information engineering, biomedical equipment, office equipment, automobiles, machinery, hardware, sports equipment, Industrial fields such as watch industry, weapons and aerospace. Therefore, it is generally believed that the development of this technology will lead to a revolution in parts forming and processing technology, known as "the most popular part forming technology today" and "21st century forming technology." It was invented by Parmatech in California in 1973. In the early 1980s, many countries in Europe and Japan also invested a lot of energy to start researching this technology, and it was rapidly promoted. Especially in the mid-1980s, this technology has achieved rapid development since its industrialization, 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 have been engaged in product development, development, and sales of the process technology. Japan is very active in competition and has outstanding performance. Many large companies have participated in the promotion of the MIM factory industry. These companies include Pacific Metals, Mitsubishi Steel, Kawasaki Steel, Kobe Steel, Sumitomo Mine, Seiko Epson, Datong special steel, etc. At present, there are more than 40 companies specializing in the MIM industry in Japan, and the total sales value of its MIM industrial products has already surpassed Europe and has followed the United States. So far, more than 100 companies worldwide have been engaged in product development, development and sales of this technology. MIM technology has therefore become a very active frontier technology field in the new manufacturing industry and has been pioneered by the world metallurgical industry. Represents the main direction of powder metallurgy technology development MIM technology. Metal powder injection molding technology is a cross-disciplinary product that integrates plastic molding technology, polymer chemistry, powder metallurgy technology and metal materials science. The mold can be used to inject blanks and quickly produce high density and high precision through sintering. 3. Three-dimensional complex shape structural parts can quickly and accurately materialize design ideas into products with certain structure and functional characteristics, and can directly mass produce parts, which is a new change in the manufacturing technology industry. The process technology not only has the advantages of less conventional powder metallurgy process steps, no cutting or less cutting, and high economic efficiency, but also overcomes the shortcomings of traditional powder metallurgy process products, uneven materials, low mechanical properties, difficult to form thin walls, and complex structures. Especially suitable for mass production of small, complex and special metal parts with special requirements.
