As a new type of processing and forming technology, the development of metal powder injection molding are influenced by several key factors, these factors determine the development prospects of the technology, the development speed and development trend. Study well, these factors can promote the further development of metal powder injection molding, solved bad will be the resistance of development.
Material consists of Metal injection molding technology includes metal powder and binder. In simple terms, metal powder and binder with certain proportion, mixing according to the rules of feed way and order at high temperature and the effect of shear stress to obtain the uniform structure of feeding, and then the granulate. Due to the existence of the binder, granulated materials has good flow property on when injection, and can be fully populated into the mold cavity. After forming, the green body through degreasing process to remove the organic component, and then sintering and densification, the finished product can be obtained.
Since the 1970s to the present just a few decades, metal powder injection molding technology has made great development and progress, but also exposed some deficiencies of the current technical route and process route. These weaknesses objectively prevent the development of the technology to a deeper level. Thus solving these deficiencies is the top priority.
