Metal injection molding is net a shape forming technology and that is the primary advantage it has. Compared with the traditional metallurgy techniques, MIM parts can be as complex, in terms as shape, as anything that can be done in plastic injection molding but achieve material properties equivalent to wrought materials. This unlocks a tremendous amount of value in terms of reducing expensive machining operations or even eliminating them entirely. When compared to casting and machining, MIM is able to offer better scalability at a lower price and is able to deliver consistently better microstructures in most material applications. MIM parts can be machined and surface treated with the same processes for machined, stamped, or cast components.
Above all, MIM parts offer a higher freedom to designers to use difficult-to-machine materials that can be better suitable to application, and complex shapes that are otherwise difficult to manufacture.
Traditional manufacturing process:
- In order to suit the production process, the geometry of the machined parts is simple.
- Mass: 43g→25g
- As the function of parts increases, the degree of complexity increases.
- Waste material and production time is reduced.
- MIM is more cost-effective compared with machining for complex metal parts.
