MIM 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. As a near-net-shape technology for manufacturing high-quality precision parts, MIM technology has advantages that conventional powder metallurgy, machining and precision casting methods cannot match. Comparison of MIM process and traditional powder metallurgy process: 1. MIM process has high degree of freedom in shape, which cannot be achieved by traditional powder metallurgy. Because MIM process not only has the advantages of traditional powder metallurgy process, but also uses fine powder, so MIM The finished product density of the process is high. 2. The particle size of the raw powder used in MIM 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 fluidity of the casting liquid, such as aluminum and zinc alloys. However, due to material limitations, the strength, wear resistance, and corrosion resistance are generally limited. The MIM process can process more raw materials. MIM injection molding The above is the comparison between the MIM process and the traditional powder metallurgy process. The MIM process can quickly produce parts with complex shapes in large quantities and at low cost, with high material utilization and avoiding more secondary machining.
