What is the difference between MIM process and traditional powder metallurgy process? MIM is a molding method in which a plasticized mixture of metal powder and its binder is injected into a mold. The selected powder is mixed with the binder first, then the mixture is granulated and then injected into the desired shape. As a near-net-shape technology for manufacturing high-quality precision parts, MIM technology has advantages that traditional powder metallurgy, machining and precision casting methods cannot match.
Comparison of MIM process and traditional powder metallurgy process:
1. MIM process has a high degree of freedom of shape, which cannot be achieved by traditional powder metallurgy. Because the MIM process not only has the advantages of the traditional powder metallurgy process, but also uses fine powder, the final product of the MIM process has a high density.
2. The particle size of the original 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 based on the strength and filling density of the mold, and the shape is mostly two-dimensional cylinders.
3. Traditional powder metallurgy can usually be used for materials with low melting point and good casting fluidity, such as aluminum and zinc alloys. However, due to material limitations, strength, wear resistance and corrosion resistance are usually limited. The MIM process can handle more raw materials. The above is the comparison between the MIM process and the traditional powder metallurgy process. The MIM process can produce parts with complex shapes quickly, in large quantities and at low cost, has a high material utilization rate, and avoids more secondary processing. The development of industry stems from people's yearning for a better life, and the driving force of innovation stems from the quality requirements of competition. In the new era, everything is showing a good trend of upward development. Ruilong, located in the beautiful Qinhuangdao, the founder has experienced more than ten years of technological precipitation and scientific history, pioneered in the powder injection and feed industry, and discovered a scientific research concept combining innovation and pragmatism. Integrating the voice of struggle in the MIM era, it opens a new chapter for the technological era! It has made new contributions to the development of new metal materials.
