Development history of ceramic injection molding technology

- Feb 11, 2021-

1. Powder injection molding originated from a hot die-casting molding technology in the 1920s. At that time, it was used to produce automobile spark plugs and other products.

2. In the 1950s, a large number of hard alloys, refractory cermets, etc. were trial-produced with epoxy resin as a binder, indicating the status of this technology in application. But because of the lack of theory. In addition, there are a series of deficiencies in technologies such as powder milling, molding and sintering, which are still far away from application.

3. By the 1980s, the development and breakthrough of basic research in the field of cemented carbide and ceramics, such as the preparation of ultra-fine powder. The development of advanced ceramic toughening theory and technology. The performance of materials prepared by this process has been much better than that in the 1950s. The big improvement has prompted PIM to be a more mature preparation and molding technology for products with complex shapes.

4. The global sales revenue of ceramic powder injection molding products has increased from 45 million U.S. dollars in the late 1980s to 420 million U.S. dollars in the late 1990s, and is growing at an annual rate of 20% to 25%.

However, only the PIM industry in the U.S., European states and Japan is relatively mature, while South Korea, Singapore, China, Taiwan, India and other places have established PIM production plants. But the output value is still small. It is ready to go.
