Medical devices leave no room for magnetic drift, corrosion or coating failure. We deliver miniature precision magnets and assemblies for infusion and dosing pumps, diagnostic instruments, dental equipment and lab automation — machined to tight tolerances, protected with application-appropriate coatings, and documented batch by batch.
What medical device engineers tell us keeps them up at night — and why magnet sourcing matters more than it seems.
As devices shrink, magnets drop below 2 mm while tolerance requirements stay absolute. A supplier without micro-machining discipline turns your compact design into an assembly yield problem.
Body fluids, cleaning agents and sterilization cycles attack unprotected magnets. Coating choice — and coating quality — determines whether your device survives its intended environment.
A dosing pump or analyzer must perform identically in year five as at calibration. Magnetic flux drift from under-specified grades or thermal exposure compromises the function your device is certified for.
Regulatory submissions and customer audits demand material traceability and inspection records. Missing documentation can block a launch even when the part itself is perfect.
Application-first engineering — we start from your operating conditions, not our catalog.
Precision magnets from ~1 mm upward, ground and sliced to tolerances down to ±0.02–0.05 mm depending on geometry — with dimensional inspection on critical features.
NiCuNi, epoxy, gold and parylene coatings selected for your exposure profile — moisture, chemicals or sterilization — with thickness and adhesion verified.
Grade selection and, where required, pre-aging stabilization treatment so the flux you calibrate against is the flux your device keeps.
Material batch records, dimensional inspection data and magnetic property measurements ship with your order — ready for your device history file.
Everything below can be customized to your drawings and specifications.
