Metal MIM powder metallurgy is the production of metal or the use of metal powder (or a mixture of metal powder and non-metal powder) as a raw material, after forming and sintering, manufacturing metal materials, composites and Process technology of various types of products.

Metal powder metallurgy products are known as one of the most popular metal component forming technologies in the world. Its main processing techniques include powder compression molding, powder injection molding and 3D printing. Metal powder metallurgy products use powder as the main raw material. The product design, formula, mold, molding process, debinding, sintering process and secondary treatment in the process of determining the characteristics ultimately determine the quality of the product.

The metal powder injection molding process is used to produce metal powder metallurgy products. This is a new type of quasi-lattice molding technology developed by combining traditional powder metallurgy technology with plastic injection molding technology, that is, metal or ceramic powder and appropriate binders. Molding is carried out by injection molding, and finally powder metallurgy products are obtained through degreasing and sintering. The main technical key is that the fine powder suitable for solid-state sintering operation should have good shape retention and better density of the sintered body. The higher the density of the powder, the higher the density of the sintered body. Composite binder additives, fully mixed and fully fed materials, high-precision molds, rapid replication of injection molding machines, fast, safe and efficient catalytic degreasing, solid-state sintering, application of metal phase diagrams, and material science knowledge to ensure compactness and preservation Shaped sintered body green embryo to obtain high-quality products.
