When metal powder injection molding (MIM) combines the characteristics of powder metallurgy and plastic injection molding, it breaks the original limitations of metal powder and makes more breakthroughs in the shape of products in the molding process. MIM uses powder metallurgy technology to sinter dense mechanical parts with good mechanical properties and surface quality. At the same time, the use of plastic injection molding technology can produce many parts with complex features in large quantities and efficiently.

Parts with complex features produced by plastic injection molding technology include external surfaces, cross-holes, recesses and key pins, surface knurling, reinforcing ribs, various external grooves, etc. Parts with these features are It cannot be obtained by conventional powder metallurgy methods, precision casting and other processes.

MIM can also improve the design freedom of products; and can design various irregular shapes such as holes, grooves, concave, sags, etc. on the parts; can add knurling, printing, trademarks and other marks on the surface and inside the holes ; It can directly process various internal and external threads; and can be coated or electroplated on the surface to make the parts more beautiful; if there are hardness or other special requirements, the product can also be processed and heat treated after sintering.
