Precision Components and Materials for Demanding Medical Applications.
Our support is focused on documented specifications, traceability and controlled production. We only state medical-specific capabilities that are actually qualified.
Typical Applications
Instruments and devices that use our magnets:
| Application | Typical Material | What Matters |
|---|---|---|
| Peristaltic & metering pumps | SmCo, NdFeB drive magnets | Long-term flux stability |
| Magnetic couplings (hermetic) | SmCo + stainless isolators | Zero-leak fluid transfer |
| Lab analyzers | SmCo assemblies, Halbach arrays | Uniform, stable fields |
| Position sensors | SmCo micro magnets | No coating to degrade |
| Surgical tool motors | NdFeB, autoclave-capable builds | Corrosion and steam resistance |
| Magnetic separation (biotech) | NdFeB arrays, beads accessories | High gradient fields |
What We Supply to Medical Devices OEMs
- ✓SmCo for critical stability — coating-free corrosion resistance and flux stability over years of service — the default choice for medical magnets
- ✓Parylene-C coatings — USP Class VI-compliant conformal coating for magnets that contact sensitive environments
- ✓Precision grinding — ±0.01 mm tolerances for sensor and instrument-grade magnets, verified on CMM and optical comparators
- ✓Clean packaging — cleanroom-style packaging with individual protection against chipping and contamination
- ✓Full lot documentation — material certs, dimensional reports, and flux measurements retained and supplied with each lot
- ✓Low-volume flexibility — we support prototype and pilot builds with the same process control as volume production
Why Medical Devices OEMs Choose China Empire
Small volumes, zero-compromise quality.
Stability Over Years
SmCo magnets with near-zero long-term drift for devices that must behave the same in year five as on day one.
Engineering Documentation
Every lot ships with certificates, dimensional data, and flux values — audit-ready for your design history file.
Prototype-Friendly
We take medical programs seriously even at pilot quantities — same engineers, same process control as full production.
