At Present in the market, the demand for various parts of the product size range is generally greater than 10mm, and the minimum thickness is between 10 ~ 30mm. If MIM products can reach 30mm size range, MIM applications will be greatly widened, especially in the field of firearms, automobiles, precision machinery, such as submachine guns, machine guns, artillery, automotive engines, mechanical arm parts etc. Metal injection molding technology have 0.3% to 0.5% dimensional accuracy, although better than precision casting products, but cannot compared with powder metallurgy,pressing and CNC machining.
If the size can be increased to ± 0.1% ~ 0.05%, close to the traditional powder metallurgy pressing and sintering process dimensional accuracy and the level of CNC machining, MIM technology will be greatly expand. On the other hand, although MIM has been used in various materials system, but regarding to the market sales, most majority of products focused on low-alloy steel, stainless steel products which have low requirement on the mechanical properties, MIM have high cost.
