The conventional processes of metal manufacturing sometimes works against Design Thinking as designers have to be limited by DFM – Design for Manufacturability. MIM removes the traditional limits of DFM and gives designers the freedom to draw complex geometries which can be smaller, integrate the components thereby delivery superior product functionality.
MIM brings freedom also in terms of material and mechanical properties. In CNC process, a standard available raw material has to be chosen. Meanwhile, MIM allows the use of alloyed fine metal powders as the raw material and customised alloys can be created to suit a particular function. For example, golf wedges can be made to weigh heavier or lighter with the same size by varying the density of the material by changing the tungsten percentage in the raw material. Similarly, in automotive applications, certain properties like higher temperature resistance or increased elongation etc. can be achieved by varying the Ni & Mo percentages in the commonly used standard medium carbon steels.
