Abstract

<p>Metal Injection Molding (MIM) process is suitable for fabricating small parts in large quantity. Fabricating the relatively large and complex shaped parts through MIM is difficult for large deformation during debinding and sintering. In order to decrease the deformation of sintered parts, powders of different size distributions 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 large and complex shaped parts could be realized by using mixed powder with smaller particle. This is because the necking of smaller powders in mixed compacts at early stage of sintering, and large powders were rocked by smaller particles.</p>
