Factors Affecting the Development of Metal Powder Injection Molding (MIM)

Oct 29, 2022

Metal powder injection molding (MIM) is a new processing and molding technology. The development of metal powder injection molding (MIM) is affected by several key factors, which determine the development prospect, speed and trend of metal powder injection molding (MIM) technology. If these factors are well studied, they can promote the further development of metal powder injection molding (MIM). If they are not well solved, they will become the resistance to its development.

The material composition of metal powder injection molding (MIM) technology includes metal powder and binder. In short, metal powder metallurgy and binder are mixed in a certain proportion under the action of higher temperature and shear force according to the specified feeding method and sequence to obtain uniform feed structure, and then granulated by the granulator. Due to the existence of binder, the granulated materials have good rheological properties when metal powder is injected on the metal powder injection molding machine, and can be completely filled into the mold cavity. After forming, the obtained green body is degreased to remove the organic components and then sintered and densified to obtain the finished product.

In the short decades from the 1970s to the present, metal powder injection molding (MIM) technology has made considerable development and progress, but it also exposed some shortcomings in the current technical route and process route. These shortcomings objectively prevent the further development of metal powder injection MIM technology, so it is urgent to solve these shortcomings. Guangdong Dahong New Materials has been committed to the research and development of metal powder injection molding (MIM) technology.
