At present, in the application process of powder metallurgy, traditional powder metallurgy and MIM powder metallurgy are two methods that are currently widely used. In particular, MIM powder metallurgy technology, as a near-net-shape technology for manufacturing high-quality precision parts, has advantages that conventional powder metallurgy, machining and precision casting methods cannot match. So which is better, traditional powder metallurgy or MIM powder metallurgy?

Comparison between MIM powder metallurgy process and traditional powder metallurgy process:

1. MIM powder metallurgy process has a high degree of freedom in shape, which cannot be achieved by traditional powder metallurgy, because MIM powder metallurgy process not only has the advantages of traditional powder metallurgy process, but also The use of fine powder, so the density of the finished product of the MIM powder metallurgy process is high.

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

3. Traditional powder metallurgy can generally be used on materials with low melting point and good casting fluidity, such as aluminum and zinc alloys. Strength, wear resistance, and corrosion resistance are all limited. The MIM powder metallurgy process can process more raw materials.

To sum up, we can see that the MIM powder metallurgy process is obviously more advantageous than the traditional powder metallurgy process. MIM powder metallurgy is a forming method in which a plasticized mixture of metal powder and its binder is injected into a mold. It is to first mix the selected powder with the binder, and then granulate the mixture and then inject the required shape. Through the MIM powder metallurgy process, complex-shaped parts can be manufactured quickly in large quantities at low cost, with high material utilization and avoiding more secondary machining.
