1988, the United States Florida World Powder Metallurgy Conference for the first time open metal powder injection molding technology, attracting experts and scholars around the world, the same year the parent company of China Steel Research, the former Metallurgical Research Institute of Iron and Steel began research and development of this process. At the end of the year, the application of MIM is most familiar to the tungsten alloy vibrator of the vibration motor of the BP machine. After 2000, stainless steel series began to widely used, we are familiar with such as fiber optic connectors, consumer electronics category hinge series, cell phone keys, sim card tray and so on. Recent MIM industry investment boom, is due to MIM parts in the mobile phone industry is widely used, and 3C industry assembly plant in China, the investment threshold to reduce, which attracted a lot of capital inflows.
The development of metal powder injection molding in the powder metallurgy industry, driven by technology more mature and stable. The metal powder metallurgy injection molding technology mainly includes the following aspects: the preparation of feed, injection molding, injection molding process of computer simulation, degreasing, sintering, MIM applications, MIM product design and specifications.
China has become the world’s automobile production power. With the vigorous development of the automotive industry, auto parts market will also be rapid development. International use of each car MIM products in Europe is 14 kg, Japan is 16 kg, the United States is 19.5 kg. While the domestic car MIM products use only about 5 kg. This also indicates that the next few years China’s automotive MIM parts market has great potential. MIM companies to seize this opportunity to improve the technical level, to meet the greater challenges.
