The basic process is as follows: firstly, the solid powder and the organic binder are uniformly kneaded, and after granulation, the film is solidified by injection molding in a plasticizing state (~150 ° C), and then chemically or thermally. The decomposition method removes the binder in the shaped body and finally densifies by sintering to obtain the final product. Compared with traditional processes, it has the characteristics of high precision, uniform organization, excellent performance and low production cost. Its products are widely used in electronic information engineering, biomedical devices, office equipment, automobiles, machinery, hardware, sports equipment, watch industry, Weapons and aerospace and other industrial sectors. Therefore, it is widely believed that the development of this technology will lead to a revolution in the forming and processing technology of parts, and is known as “the hottest part forming technology of today” and “forming technology of the 21st century”.
