2C-MIM (Two-Component MIM) process was developed for manufacturing bimetallic parts. Its main advantage is that in a production process, two materials with different properties can be combined so as to reduce the subsequent joining operations (such as welding, riveting, fastening assembly, etc.). 2C-MIM manufacturable parts range from hollow parts with complex internal structure to flexible disassembly components.

The aim of all the studies is to produce functionally enhanced parts at a favorable cost. For wear-prone parts, only the key points such as the friction surface can be strengthened with harder or more wear-resistant materials. For other structural parts, to use lower cost material. To manufacture bimetallic parts, considering the shape of the two injection materials is not enough. The key is that the two materials must be sintered in the same furnace and the same atmosphere. Because the shrinkage of two parts is different during sintering, which may lead to delamination or cracking. In addition, when harmful phases appears, alloying elements will diffuse along the boundary, which can deduct the material performance.

By coordinating the processing factors, the quality of 2C-MIM parts can be optimized. Because of its unique ability, it can make a part with different material properties without any assembly work. Therefore, 2C-MIM process will certainly expand MIM application market.
