Metal injection molding is a forming process suitable for metal products with small product structure, complex product shape or special performance requirements. It is a new technology that has developed rapidly in the past 20 years by combining plastic injection molding technology with the field of powder metallurgy.
What is the MIM metal injection molding material?
MIM Powder particle fineness, tap density and particle shape are the key indicators to determine whether the powder can be successfully used in the MIM process.
The Metal injection molding process requires very fine raw material powder (~10μm) to ensure uniform dispersion of raw materials during the production process, good fluidity during the injection process, and a relatively high sintering speed. Metal powder microstructure (*2500)
Therefore, the ideal MIM powder is: the powder particle size is "2~8μm; the density is 40%~50% under loose packing conditions; the density after vibration is more than 50%; the powder particles are nearly spherical and have a large specific surface.
At present, there are many types of MIM materials used for metal injection molding, which are usually divided into the following four categories:
1. Stainless Steels-316L, 17-4PH, 420, 430, 440, 304
2. Low-alloyed Steels-FN02, FN0205, 4605, FN08, 8620, 8740, 4140, 100Cr6, 1010...
3. Specialties Materials-ceramic, Titanium alloy
4. Soft Magnetic-Fesi3, FN50
