Metal powder injection molding technology is a new type of metal powder metallurgy near-net forming technology formed by introducing modern plastic injection molding technology into the field of powder metallurgy. Although plastic injection molding technology can produce products of various complex shapes at low prices, plastic products are not strong. In order to improve their performance, metal or ceramic powder can be added to the plastic to obtain higher strength and good wear resistance. Products. In recent years, this novel operating method has evolved to maximize the content of solid particles and completely remove the binder during the subsequent sintering process and densify the compact. This new powder metallurgy forming method is metal injection molding technology.
