11. MIM is a fast growing manufacturing method that bridges the manufacturing gap that other metal working technologies and shaping processes cannot be fulfilled because of technology or cost. MIM can be a very cost effective method for producing large quantities of precision parts. MIM Advantages High Shape Complexity: MIM process can produce more complex parts than either investment casting or traditional press and sinter techniques. Low Cost: Machining operations can be eliminated. MIM Processing Why we comment and present MIM Processing?

12. Tight Tolerances: Dimensions of parts produced with our feedstock can be held to +/- 0.001~0.002" per inch. High Density: MIM parts produced with our feedstock will have density levels between 97.5-99.5%. These l levels typically exceed traditional press and sinter techniques. High Performance: The tensile strengths, elongations and hardness are superior to traditional press and sinter techniques, and comparable to investment casting or machine components.
