Outline of Final Research Achievements

Metal Injection Molding (MIM) process is suitable for fabricating small parts in large quantity. In order to decrease the deformation of sintered parts, powders of different sizes were mixed. The effect of powder particle distribution and powder loading on the distortion of complex shaped compacts were investigated and evaluated. Smaller deformation of the parts could be realized by using mixed powder with smaller particle.
