Metal Injection Molding (MIM) – sometimes is 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
Repeatability
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
Key Attributes:
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。
