Tongcheng supplies 17-4PH and custom stainless steel powders for MIM parts requiring thin walls, complex shapes, good appearance and batch consistency.
Engineering focus: Stainless steel powder for consumer electronics
Review the material, particle-size, process and validation factors that matter for this application.
Particle size, feedstock rheology and mold design need to be matched together.
The finished look cannot be remedied by polishing alone.
The specific grade depends on the part function and post-processing route.
Typical part applications
Hinges, connectors, wearable structural parts, camera or precision mechanism parts.
Key requirements
Forming details, sintering distortion, surface defects, polishing/coating, corrosion resistance and assembly consistency.
From trial production to series production
Tongcheng supports stable feedstock, forming and sintering with particle size control and batch management, and cooperates with customers to improve size, appearance and post-processing performance.
Part requirements to evaluate first
- Hinge, connection, wearable and precision mechanical structural parts
- Projects with complex thin walls, high appearance and batch consistency requirements
Also consider these manufacturing conditions
- Minimum wall thickness, critical tolerances and surface grade
- Polishing, coating, assembly and reliability testing
Discuss your powder project
Share the process step, operating conditions and part result you want to improve.
- Part name, geometry or drawing
- Load, wear, corrosion, temperature and service-life requirements
