Our Metal Injection Molding Center of Excellence has the capacity to manufacture high-volume runs of complex metal components. We can produce medium to micro MIM parts to the following specifications:
- Mass: 0.01–400 g
- Wall thickness: 0.1–10 mm
- Part size: 0.2–200 mm
- Hole diameter: as small as 0.3 mm
- Dimensional accuracy: +/-0.5% inch/inch and less without postprocessing
- Surface finish: Ra 0.95–1.30 μm without polishing
- ISO 13485
- ISO 9001
- ASTM B883-19
Begin your MIM project
Our metal injection molding experts will work with you to develop MIM designs for your intricate metal component. We specialize in design for manufacturing (DFM) and can take your metal component from concept through validation and to full-scale production.
MIM is an excellent alternative to other metal fabrication methods such as stamping, machining, die casting and investment casting. MIM gives you the opportunity to use metal alloys that have unique characteristics or are difficult for other processes to work with. We can produce components in a wide variety of metal alloys, including:
- Iron-based alloys
- Stainless steels
- Tool steels
- Controlled expansion alloys, including Kovar®
- Soft magnetic alloys
- Tungsten alloys
- High-temperature alloys
- Cemented carbide
Compounding: To create a metal compound suitable for MIM, a powderized metal is mixed with a binding agent, creating a feedstock compound.
Injection molding: The feedstock is injected into a mold. The mold forms near-net-shape components that are about 20% larger than the finished components will be.
Debinding: Most of the binding material is removed in a debinding process, leaving behind the metal.
Sintering: The high-temperature process of sintering removes the rest of the binder and makes the components denser, resulting in finished metal parts.
Secondary operations: Secondary operations can be performed to refine components’ shape, appearance and other properties.
Begin your MIM project
While the MIM process reduces the need for many secondary operations, some specialized components may require one or more of the following operations, all of which we can provide to you:
- Coining
- Magnetic polishing
- Electropolishing
- Machining
- Heat treating
- Plating/coating
- Tapping/reaming
- Black oxide coating
- Tumbling
- Bead blasting
- Hot isostatic pressing (HIP)
