MIM is a process in which a plasticized mixture of a metal powder and its binder is injected into a model. The powder is first mixed with the binder, and then the mixture is pelleted and injected into the desired shape. MIM technology, as a kind of near-net forming technology for manufacturing high quality precision parts, has incomparable advantages compared with conventional powder metallurgy, machining and precision casting methods.

Comparison between MIM process and traditional powder metallurgy process:

1. MIM process has a high degree of freedom in shape, which is beyond the reach of traditional powder metallurgy. Because MIM process not only has the advantages of traditional powder metallurgy process, but also USES fine powder, MIM process has a high density of finished products.

2. The particle size of raw powder used in MIM is 2-15 m, while that of traditional powder metallurgy is mostly 50-100 m. Traditional p/m is limited to the strength and filling density of the mold, and the shape is mostly two-dimensional cylindrical.

3, the traditional powder metallurgy method can be used for aluminum and zinc alloy and other materials with low melting point and good casting fluid mobility, but generally due to the limitation of materials, resulting in the strength, wear resistance, corrosion resistance are limited. The MIM process can process more raw materials.

So much for the comparison between the MIM process and the traditional powder metallurgy process. The MIM process can produce complex shaped parts in large quantities and at a low cost, with high material utilization and avoiding more secondary machining.
