Evaluate MIM filling, dimensions after sintering, polished surfaces, corrosion resistance and assembly performance together for watch crowns, pushers, connectors, decorative structures and miniature precision parts.
This page is a typical project plan and does not correspond to a specific customer name or unconfirmed delivery results.
Divide similar projects into four executable links
Demonstrate how watch micro-components can simultaneously control complex structures, assembly dimensions, sintered pores, polished surfaces and corrosion resistance.
Project goal: balance miniature geometry and visible surface quality
Watch and clock parts often focus simultaneously on grooves, threads or thin-wall construction, assembly tolerances, polished appearance, feel and corrosion resistance in everyday environments.
Common difficulty: Sinter pores exposed after polishing
Insufficient powder buildup, injection density, debinding and sintering densification may result in pitting, holes or uneven gloss after grinding and polishing.
Tongcheng approach: evaluate material, particle size and surface finishing together
Compare 17-4PH, austenitic or project-type materials based on strength and corrosion resistance targets, and evaluate complete particle size, sintered density along with subsequent processing and passivation routes.
Verification focus: critical dimensions and finished product appearance
It is recommended to evaluate sintering shrinkage, hole location and fit, surface porosity, polished gloss, corrosion resistance and functional performance after assembly on real parts.
The engineering team can further evaluate based on actual grade, particle size, process, target results and procurement plan.
