Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a"feedstock" that is then shaped and solidified using injection molding.The ability to combine several operations into one process ensures MIM is successful in saving lead times as well as costs, providing significant benefits to manufacturers. The metal injection molding process might be a green technology due to the significant reduction in wastage compared to "traditional" manufacturing methods.
MIM process
The injection molding process starts by taking fine powder metallurgy and mixing it with a binder material. The product of mixing metal powders with a binder is called "feedstock." In addition to producing a feedstock, a mold is also created for your final product. The feedstock is then injected into the mold where it is allowed to set and solidify. Once the injected metal has set, the binder removal procedure starts. This process varies depending on the type of binder initially employed.
Typically, there are multiple steps in the debinding process. Each part usually goes through more than one cycle to ensure maximum removal of the binding material before sintering. After debinding is finished, the part is semi-porous. This allows the secondary binder to more easily escape during the sintering cycle. Debinding is a critical step as without it the part would not be as sturdy.
Finally, the product must undergo a sintering process, which ensures that all the parts produced have the correct wall thickness, geometry, material composition, and physical properties. Using this process, a high volume of products can easily be made.
Metal injection molding MIM applications
A significant advantage of MIM parts is the ability to combine design complexity with high volume when producing small parts. MIM parts can be comparable to die cast parts in terms of quality. In fact, it is possible to efficiently produce parts through metal injection molding, where it would be difficult or nearly impossible to do with other methods.
Where metal injection molding stands out is its ability to create hard and durable parts with tight tolerances. A knowledgeable manufacturing partner can produce parts that are accurate to 3mm.
A part's application can play a large role in deciding if metal injection molding vs. die casting is the best option.
By combining multiple operations, this method could also save manufacturers substantial lead time.
Metal injection molding was developed in the late seventies and has grown exponentially in popularity as many industries recognized its value.
- Firearms - triggers, safety, magazine catch, fire suppression.
- Medical device industry - articulation gears, joint replacements, drug delivery devices.
- Automotive - turbocharger vanes, rocker arms, shift levers.
- Consumer electronics - lightning connectors, heat sinks, cold plates, fiber optic parts, and various mobile phone parts.
- Aerospace - flap screws, engine components, valve holders, and rocket burners.
