focusing on micro-sized and irregular structural parts

Manufacturing process

Metal Injection Molding (MIM) is an emerging near-net shape technology that combines traditional powder metallurgy processes with modern plastic injection molding processes. The process generally consists of four stages: feedstock preparation - injection molding → debinding treatment → sintering. Specifically, metal powder is first uniformly mixed with organic binders to form a feedstock, which is then heated and injected into the mold cavity using an injection molding machine to obtain the injection molded part. Next, the binder and other components in the injection molded part are debound to obtain the green part. Finally, the green part is sintered and densified to obtain the final product. The finished product is similar to conventional metal products and can undergo subsequent processes such as polishing, shaping, and heat treatment to obtain mechanical parts that meet design requirements.

MIM process technology characteristics
