(A) Comparing with Traditional PM
 As a net shaping technology manufacturing high quality precision parts, MIM enjoys advantages that regular PM can��t compare with. MIM is able to manufacture many parts with complicated shapes: for example, external grooving, external thread, cone-shaped external surface, cross hole, blind hole, dented surface and key pin, stiffener, surface knurling etc. Parts with the above characteristics can��t be made with regular PM.

(B) Comparison between MIM and Machining
Currently, traditional Machining relies on atomization to improve its processing capability, with efficiency and precision greatly improved. However, basic procedures of gradual processing (turning, digging, milling, rubbing, drilling and polishing etc) to finish parts shaping are indispensible.

The Precision of Machining Process is far superior than other processing methods, but some parts can be made with machining due to its low effective utilization rate of material and shape limitation to equipment and tools. On the contrary, MIM can effectively utilize the material, not limited to shapes. In the manufacturing of small precision parts with difficult shapes, MIM is with relatively low cost, high efficiency and strong competiveness compared to machining processing. MIM technology makes up the technical insufficiency and unachievable regrets of traditional processing methods, but not competing with traditional processing methods. MIM technology can give full play of its strengths in parts that can��t be made with traditional processing methods.

(C)Comparison between MIM and Precision Casting
As for metals or alloys with relatively low melting points, precision casting can shape parts with complicated 3D shapes; as for metals and alloys, hard alloys and metal ceramic etc that are hard to melt, precision casting is rendered powerless, which is determined by the nature of precision casting. In addition, it is very difficult or infeasible to process parts of small sizes, thin walls and large quantity with precision casting.
