The development of metal powder injection molding is influenced by several key factors.

a new type of forming technology, the development of metal powder injection molding is affected by several key factors. These factors determine the development prospects, development speed and development trend of the technology. These factors are well studied, can promote the further development of metal powder injection molding, and can not solve the problem of the development of the resistance.          

Metal injection molding technology of the material composition, including metal powder and binder two parts. Simply put, the powder metallurgy and metal binder in certain proportion, according to the provisions of feed mechanism and order in under the action of high temperature and shear stress were mixing and uniform structure of feeding and the granulator granulation. Due to the presence of binder, granulating material in the injection molding machine injection has good rheological property, can be filled completely to the cavity of the mold. After the forming, the body is obtained by taking off the organic component of the body and sintering the densification process, and the product can be obtained.          

From the seventies of the 20th century to the present only lasts for a few decades time, metal powder injection forming technology has made considerable development and progress, but from the development also exposed some of the shortcomings of current technical route and process route. These deficiencies in the objective to prevent the technology to a deeper level of development. So it is urgent to solve these problems.
