How to distinguish the MIM process of metal injection molding from the traditional powder metallurgy process?

Powder metallurgy has unique chemical composition, mechanical and physical properties, which cannot be obtained by traditional melting and casting methods. What is the difference between MIM process and traditional powder metallurgy process? The following is the share of zhongwei precision editor:

Comparison between metal injection molding MIM process and traditional powder metallurgy process:

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

2. The particle size of raw material powder used in MIM for metal injection molding is 2-15 μ m. However, the particle size of raw powder in traditional powder metallurgy is mostly 50-100 μ m。 Traditional powder metallurgy 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 generally be used for materials with low melting point and good liquid fluidity, such as aluminum and zinc alloys, but its strength, wear resistance and corrosion resistance are generally limited due to material limitations. Metal injection molding MIM process can process more raw materials.
