Metal Injection Molding (MIM)
Metal Injection Molding (MIM) – sometimes called Powdered Injection Molding (PIM) – is an advanced metal forming technique that uses injection molding equipment for manufacturing both simple and complex metal parts to tight tolerances. MIM can be used across a wide range of components, but the best applications are typically small and weigh less than 100 grams, though larger parts are possible. The MIM process can replace other metal forming techniques such as investment casting and machining.
Advantages of MIM
- Complex geometries
- Efficient use of material
- Less material waste as a result of producing near net shape components and considered a green technology
- Excellent mechanical properties
- Tailored solutions using unique materials formulated to meet component/application requirements
- MPP materials can be brazed/joined to a variety of components for complete assembly solutions
- MIM is a repeatable process for complex components made from high-temperature alloys.
- MIM parts are near fully dense, which provides excellent mechanical, magnetic, corrosion, and hermetic sealing properties, and allows secondary operations like plating, heat treating, and machining to be easily performed.
- Complex shapes are achieved through innovative tooling techniques similar to those used in the plastic injection molding industry.
- High volumes are attained through multi-cavity tooling.
MPP’s MIM materials include all standard alloys and application-specific alloys, upon request.
As part of our MIM process, we offer low-cost prototyping, an experienced process and metallurgical team, and tool transfers from other MIM producers. We are ISO 9001:2008 registered and support JIT and Kanban programs.
MIM provides design freedom that enables creation of metal parts once too expensive to make based on complexity or production scale.
Do you have a part tailored specifically for a competing metal forming method like casting? Our design team specializes in converting components from other metal forming methods using MPP’s Conversioneering® process.
For more than 40 years, MIM has been a standard process for manufacturing small, complex components that meet the diverse and demanding requirements of industries worldwide.
The MIM process uses a wide array of alloys and metals. From stainless steel to tungsten alloy to low alloy steel, and more, MPP provides expertise in working with any material used in the MIM process. MIM is an excellent alternative to other forming processes, including Inconel casting for aerospace manufacturing.
