metal injection|What is metal injection molding

MIM technology originated in some European countries, and was first used in the development and application of military equipment components. In recent years, through the introduction of MIM technology in the Yangtze River Delta region in China, with continuous exploration and practice, it has been successfully applied to many popular fields such as auto parts, 3C digital products, medical equipment, tool locks and so on.
Metal powder injection molding technology (MIM for short) is a new type of powder metallurgy near-net forming technology formed by introducing modern plastic injection molding technology into the field of powder metallurgy. It is a forming method in which a plasticized mixture of metal powder and its binder is injected into a mold.
Process flow
The MIM manufacturing process generally includes: mixing and granulating, injection molding, degreasing, sintering, and secondary treatment. Combining the flexibility of injection molding design with the high strength and integrity of precision metal, it is suitable for mass production of small, precise, complex shapes and metal and ceramic parts with special performance requirements. It has broad application prospects and economic value.
