Stainless steel,iron-base,magnetic material,tungsten alloy,carbide alloy and fine ceramic material and so on are suitable for Metal injection molding process,and the MIM components are widely used on aerospace industry,automotive industry,military industry,medical industry,mechanine industry and household appliance industry,etc.Then comparing with other traditional process,what superiorities does MIM possess?
1,Comparing with traditional powder metallurgy process: MIM as a modern near net forming technology which is adopted to produce high-quality and high-precision spare parts,enjoying the unique superiorities.We could produce the parts with high complex structure by MIM,such as external grooving,external thread,crossing through hole,blind hole,concave platform,etc.
2,Comparing with precision casting process: Precision casting could produce the complex 3D structure parts with the metal or alloy material with low melt point,but it is impossible to form if using carbide material,metal ceramic material and some refractory metal and alloy material.Meanwhile,it is difficult for it to produce the parts with small dimension,thin wall and massive quantity.
3,Comparing with machining Automatic machining opearation could improve its production capability,so a great progress has been realized,but the basic machining process is still inseperable from gradual processing(Turning,planning,milling,grinding,drilling,polishing,etc.) to finish the shaping. Although the precision of machining process is much superior than other process,the efficient material utilization rate is low and the structure is limited to machining equipment and tools,so some components couldn't be formed.Contrary,MIM could realize the material utilization 98% and the structure is free and unrestricted.For the production of the precise parts with small size and high difficult shape,MIM is low-cost,high-efficient and competetive.So MIM could display its superiorities on the parts that couldn't be done by machining.
