With the rapid development of smart devices across consumer electronics, medical technology, and industrial applications, internal metal components are evolving toward greater miniaturization, lightweighting, and structural integration. To meet this trend, MIMO Metal has developed a highly complex, assembly-ready metal component using the Metal Injection Molding (MIM) process. This part demonstrates excellent structural flexibility, dimensional precision, and mass production consistency, and has now entered full-scale production.
The component is manufactured using 17-4PH stainless steel, offering a well-balanced combination of mechanical strength and corrosion resistance after heat treatment. Key performance indicators include:
Tensile strength: ≥1100 MPa
Yield strength: ≥1000 MPa
Hardness: HRC38–45
Density: ≥7.70 g/cm³
17-4PH is widely used in high-performance structural applications due to its excellent balance of strength, hardness, and corrosion resistance, making it especially suitable for components requiring dimensional stability and long-term reliability in smart devices.
The part features an exceptionally complex design, including multi-layer geometry, precision cavities, interlocking snap fits, and guiding grooves. Leveraging the advantages of the MIM process, the component is manufactured in a single molding step without the need for assembly or welding, significantly improving structural stability and manufacturing efficiency.
One-piece molding: Eliminates the need for multiple machining steps and secondary assembly, reducing structural errors.
Tolerance control at ±0.03 mm: Ensures precision mating with other components.
Lockable post-molding assembly: Enhances flexibility in modular design for smart devices.
This design approach offers greater freedom for internal layout in compact products such as wearable electronics, sensor housings, and embedded smart modules.
To ensure stable mass production of such a complex part, MIMO Metal focused on optimizing the following technical challenges during process development:
Injection simulation and mold refinement to resolve thin-wall filling and venting balance issues
Tightly controlled debinding and sintering curves to minimize distortion and control shrinkage
Consistent heat treatment to ensure batch uniformity in hardness and dimensions
Dimensional chain analysis to maintain accurate alignment and tactile performance during assembly
Batch production data shows that post-sintering dimensional deviation is controlled within ±0.025 mm, with a finished yield rate exceeding 95%, proving strong readiness for volume production.
This project showcases the capabilities of the MIM process in manufacturing highly complex, precision-assembled metal parts for smart devices. Through coordinated optimization of design, materials, and processing, MIMO Metal provides a cost-effective and functional solution that supports trends in lightweighting, modularity, and integration.
Looking ahead, we will continue expanding the application of these structures in smart terminals, medical devices, and wearable technologies—delivering more reliable and flexible precision metal components for the future.
