Introduction to Metal Injection Molding Powder Metallurgy Precision Metal Manufacturing Process

For parts with more precise powder metallurgy dimensions, the necessary post-treatment is required. This process is the same as the heat treatment process of conventional metal products. What are the injection molding powder metallurgy precision metal manufacturing processes? Zhongwei Precision Powder Metallurgy Factory will give a brief introduction:

Features of the MIM part process. Compared with other processing processes, the particle size of raw material powder used for MIM parts is 2-15 μ m. The particle size of the original powder of traditional powder metallurgy is mostly 50-100 μ m。 Due to the use of fine powder, the final product density in the MIM part process is very high. MIM part technology has the advantages of traditional powder metallurgy, and traditional powder metallurgy can not achieve a high degree of shape freedom. The traditional powder metallurgy is limited to the strength and filling density of the die, and the shape is mostly two-dimensional cylinder.

The traditional precision casting drying process is an extremely effective technology for manufacturing products with complex shapes. In recent years, ceramic cores can be used to complete the finished products of slit and deep hole. However, due to the limitation of liquid fluidity, the strength of pottery core and casting still has some technical problems.

Generally speaking, this process is more suitable for manufacturing large and medium-sized parts, while small and complex shapes are more suitable for the process of MIM parts.
