Introduction To Mim
Dec 20, 2018

Metal injection molding (MIM) is a forming method in which a plasticized mixture of metal powder and its binder is injected into a mold. It is the shape required to first mix the selected powder with the binder and then pelletize the pellet for injection molding. The polymer imparts its viscous flow characteristics to the mix, aiding in the uniformity of forming, cavity filling and powder loading. After the forming, the binder is removed and the degreased blank is sintered. Some sintered products may also undergo further densification, heat treatment or machining. The sintered product not only has the same complex shape and high precision as the product obtained by plastic injection molding, but also has physical, chemical and mechanical properties close to the forging. This process technology is suitable for the mass production of small, precise, three-dimensional shapes and metal parts with special performance requirements.
