Metal injection molding is an advanced manufacturing process in which, metal and a binder mixed material are used to produce a complex part.
Metal injection molding typically follows these steps:Â
- Feedstock Preparation.
- Molding
- Debinding
- Sintering
- Secondary
This manufacturing method allows to production metal parts with complicated shapes and small tolerances, with the ease and automation of the injection molding machine.
MIM is used to produce incredibly strong, highly complex metal components in medium to very high annual volumes. With excellent corrosion resistance and the availability of custom alloys, it is ideal for demanding applications where only the best will do.
MIM offers greater design freedom than many other production processes by freeing designers from the traditional constraints associated with trying to shape low alloy steel, stainless steel, nickel iron and titanium.
Advantage of MIM
- Superior Quality and Highly Complex Parts
- Small and Precise Components
- Consistency and Repeatability
- High Production Volume with Short Lead time
- Excellent mechanical properties
- Lower overall product cost
- Tailored solutions using unique materials.
