Performance and cost analysis of injection molded products

MIM process uses micro- fine powder, which not only can accelerate sintering shrinkage and help to improve the mechanical properties of material, extend fatigue life of material, but also improve resistance to stress corrosion and magnetic properties. For over tough materials, too hard to cut brittle materials or segregated parts with complex geometry in casting or contaminated, MIM manufacturing process can save cost greatly.

For example, a typewriter guide rod, usually it takes 14 process but only six process by MIM manufacturing process, which saves about half of the cost. When the material cost / production cost ratio increases, the potential cost will be more able to reduce. Therefore, the smaller the more complex parts, the better economic benefits will be. Through above analysis, we can see the potential of MIM molding is great.
