Metal Injection Molding Process

What is Metal Injection Molding?

Metal Injection Molding (MIM) is a precision manufacturing process that combines the versatility of plastic injection molding with the mechanical properties of metals. This innovative technique allows for the production of complex, high-precision metal components with excellent surface finish and tight tolerances.

High Precision

MIM technology enables the production of intricate geometries and complex shapes that are challenging or impossible to achieve with traditional manufacturing methods.

Cost-Effective

For small to medium-sized components produced in high volumes, MIM offers significant cost advantages over machining, investment casting, and other manufacturing processes.

Material Versatility

MIM supports a wide range of materials including stainless steels, low alloy steels, tool steels, titanium, and superalloys, providing excellent mechanical properties.

The Metal Injection Molding Process

The MIM process combines the design flexibility of injection molding with the material properties of metals, enabling the production of complex components with high precision and efficiency.

1

Feedstock Preparation

Metal powders are mixed with a binder system to create a homogeneous feedstock with suitable flow properties for injection molding.

2

Injection Molding

The feedstock is injected into a mold cavity under high pressure, forming the desired shape. The process is similar to plastic injection molding but uses metal-based feedstock.

3

Debinding

The binder is removed from the molded part through thermal or chemical processes, leaving a porous metal structure that retains the shape of the original component.

4

Sintering

The debound part is sintered at high temperatures, causing the metal particles to bond together and densify. This results in a component with near-full density and excellent mechanical properties.

5

Finishing

Optional secondary operations such as machining, heat treatment, surface finishing, or plating may be performed to achieve specific requirements.

Advantages of Metal Injection Molding

MIM offers numerous benefits over traditional manufacturing methods, making it the preferred choice for complex, high-precision metal components.

Complex Geometries

MIM can produce intricate shapes with features such as undercuts, thin walls, and internal cavities that are difficult or impossible to achieve with traditional machining.

High Precision

MIM components typically achieve tolerances of ±0.3%, with secondary operations available for even tighter specifications.

Excellent Surface Finish

MIM parts typically have a smooth surface finish (Ra 1.6-3.2 μm) as-sintered, reducing or eliminating the need for secondary finishing operations.

Material Efficiency

MIM has a material utilization rate of over 95%, minimizing waste compared to subtractive manufacturing processes like machining.

Cost-Effective

For high-volume production, MIM can reduce costs by 30-50% compared to machining or investment casting due to fewer secondary operations and lower material waste.

Design Flexibility

MIM allows for design changes with minimal cost impact compared to traditional manufacturing methods, enabling rapid prototyping and product iterations.
