Metal Injection Molding Components "METAMOLD™"
Metal Injection Molding (MIM) is a manufacturing technology that enables
mass production of metal parts with complex shapes
It is commonly referred to as Metal Injection Molding (MIM).
It is a manufacturing method for metal parts belonging to the category of powder metallurgy.
This manufacturing method combines characteristics of both injection molding and powder metallurgy.

Industrial Equipment Sector
Ball Screw
We manufacture “circulation components,” which are key parts of ball screws.
We can accommodate various circulation system types.
- return piece
- return tube type (split)
- end deflector type (split)
- return piece (split)
- end cap type
- return plate type
Other applications
By taking advantage of the high design flexibility that is a hallmark of the MIM process, we manufacture components that incorporate the necessary functions into limited spaces.
■Examples of Applications
- Positioning units
- Conveying units
- Fluid units
- Temperature control units
- Measurement and inspection units
- Digital data units
- Power and drive system units
and more
Difficult-to-machine materials
Applications of MIM (Metal Injection Molding)
・The MIM process enables the handling of high-melting-point materials.
We offer not only standard steel and stainless steel products, but also a comprehensive lineup of specialty materials and difficult-to-machine materials.
MIM enables the production of materials that are difficult to manufacture using other methods, such as soft magnetic materials, titanium alloys, and low thermal expansion materials.
・In the titanium category, we can manufacture using not only pure titanium, but also Ti-64 material that meets ASTM standards for medical applications and is suitable for implantable devices.
・Choosing the MIM process makes it possible to form even complex shapes from difficult-to-machine materials, allowing machining allowances to be optimized and machining steps to be eliminated.
It can also be applied to various fields.

Improved microstructure and design aesthetics / Metal 3D printer
Improved microstructure and design aesthetics
■Enhanced design aesthetics through embossed transfer printing
This technology transfers patterns etched or laser-engraved onto molds onto the molded parts.
The photo shows the result of applying this technique to a mold used in our MIM process to transfer a pattern onto the final product.
These patterns and textures can be selected from over 100 available samples, or custom patterns can be created based on a provided model.
Even parts that are difficult to machine can be easily produced using transfer forming with a mold.
Metal 3D Printer
■Recommended for the following:
・Those who want to make metal parts first, or who need metal prototypes.
・Those in the design review phase and want to evaluate functionality with various shapes.
・Those who want to make metal parts as mockup samples.
・Those who, because MIM requires expensive tooling costs, are considering using 3D printing for the initial small batch
・Those who want to evaluate multiple design options by producing them as metal parts.
・Those who want to make one-off items or extremely small quantities of prototypes.
