A solution to this problem has been succeeded in finding now. The key is in creating the correct atmosphere in the sintering furnace. A low-oxygen environment is usually used to prevent the complete oxidation of a metal powder. By contrast, with aluminium, an oxygen-rich atmosphere has been found to be beneficial. The aluminium oxide layer of the particles is so thick that the particles are protected from complete oxidation. At the same time, the oxygen aids the combustion of the carbon contents of the binder material.

Metal injection molding (MIM) is to uniformly mix the powder and the binder, and then the mixture is granulated by a granulator and then injected into a forming mold cavity to complete the desired shape. The mixed melt has good fluidity after heating, which aids in the forming of the product during injection and maintains the density uniformity of the product. The shaped product also needs to be degreased and then sintered in a sintering furnace, and some products need some post-treatment such as tapping, polishing and coating.
