Watch and miniature metal components require complex forming, surface quality, corrosion resistance, strength, dimensional accuracy and consistent assembly. Evaluate 17-4PH or custom materials according to the component’s function.
Engineering focus: Stainless steel powder for watch components
Review the material, particle-size, process and validation factors that matter for this application.
Different parts have different load, friction and appearance requirements.
There are also tooling, shrinkage and post-processing costs to consider.
The appearance and corrosion resistance come from the complete process chain.
Different parts have different concerns
Clasps, connectors, buttons, structural frames and small transmission parts are subject to different load, friction, appearance and size requirements, and performance priorities need to be defined separately.
MIM for complex miniature geometries
Cross holes, grooves, thin walls, curved surfaces, and multifunctional integrated designs may be suitable for MIM, but tooling, debinding, sintering shrinkage, and post-processing costs need to be evaluated together.
Surface quality comes from the complete process chain
Powder particle size, sintering pores, grinding and polishing, cleaning and passivation will all affect appearance and corrosion resistance. The surface grade and acceptable defects should be clarified during the design stage.
Part requirements to evaluate first
- Clasps, micro-connections, buttons and structural parts
- Volume parts with thin walls, slots, or complex surfaces
Also consider these manufacturing conditions
- Critical dimensions, appearance grade and cycle life
- Material status, polishing, plating or passivation route
Discuss your powder project
