    Feedstock preparation plays a central role in the MIM process. The availability of various mixing devices has allowed different methods of mixing to be used to produce MIM feedstock. These range from sigma blade mixers, twin screw extruders, and kneaders to planetary mills. Regardless of the methods of mixing used, the feedstock mixture should be homogeneous and possess a pseudo-plastic behaviour.
