Kovar Machining for Medical Devices & Diagnostic Electronics
Custom CNC-machined Kovar (ASTM F15, Fe-Ni-Co) housings, lids, rings, frames, and flanges for hermetic, high-reliability medical and diagnostic electronics. Prototype to low-volume production with DFM support, burr control, material traceability, and dimensional documentation.
Hermetic Reliability for Critical Applications
Kovar's unique properties make it the material of choice for sealed, high-performance medical and diagnostic systems where failure is not an option.
Hermeticity & Reliability
CTE-matched Kovar (ASTM F15) performs with glass, ceramics, and brazes in sealed enclosures for sensors, detectors, and precision electronics.
Thermal Cycle Stability
Dimensional and sealing stability across cleaning, sterilization, and operating environments critical for medical devices.
EMI/RF Shielding
Fe-Ni-Co alloys help protect sensitive mixed-signal and RF systems found in diagnostic analyzers, imaging, and surgical equipment.
Photonics Integration
Common in laser modules, optical detectors, and medical photonics assemblies where alignment and sealing are critical.
What We Make for Medical & Diagnostic Applications
- Kovar housings and enclosures for hermetic electronics
- Lids, caps, and covers with controlled flatness and sealing geometry
- Sealing rings, frames, and flanges for glass-to-metal and ceramic-to-metal interfaces
- Thin-wall and small-feature precision components for compact assemblies
- Custom features for sensors, RF/microwave modules, and photonics packages
Built for the Challenges of Kovar
Kovar machining responds differently than common alloys. Our processes are structured around four core disciplines.
Heat Management & Work-Hardening Control
Precision feeds, speeds, and coolant strategies prevent thermal buildup and work-hardening that can compromise machinability and surface integrity.
Burr Prevention & Removal
Dedicated burr control on sealing surfaces and edges ensures clean assembly and reliable hermetic seals without secondary rework.
Thin-Wall & Small-Feature Stability
Fixturing and toolpath strategies minimize distortion on thin-wall geometries and delicate features common in compact medical assemblies.
Dimensional & Cosmetic Control
Critical sealing features are held to tight tolerances with cosmetic standards aligned to medical and high-reliability expectations.
Precision Machining for Medical & Diagnostic Electronics
CNC Turning & Milling
Multi-axis CNC turning and milling for complex geometries, tight tolerances, and fine surface finishes on Kovar and Fe-Ni-Co alloys.
Prototype & Low-Volume Production
From early-stage prototypes to repeat production batches with consistent quality, traceability, and documentation.
Deburring & Finishing
Burr-free sealing and assembly surfaces with finishing tailored to brazing, glass sealing, welding, and downstream processes.
Inspection & Certification
Material certification, lot traceability, and dimensional documentation per your drawing requirements.
DFM Feedback
Design-for-manufacturability input before machining, helping you optimize designs for cost, quality, and lead time.
Process Alignment
Features, finishes, and allowances controlled for downstream brazing, glass sealing, welding, and assembly processes.
Documentation, Certification, and Communication
- Material certificates for Kovar / ASTM F15 / Fe-Ni-Co alloys
- Lot/heat traceability for each build
- Dimensional documentation and inspection reports to your drawing
- Clear, responsive communication with your engineering and quality teams
- Custom documentation packages: FAIR, measurement plans, inspection checkpoints
