Hermetic Electronic Packages & Sealing Components
Precision CNC machining of Kovar (ASTM F15) and Fe‑Ni‑Co alloy components for hermetic, high‑reliability sealing applications. From prototypes to production with burr control, thin‑wall expertise, material traceability, and full inspection support.
What We Machine for Hermetic Packaging
We produce custom Kovar (ASTM F15) and Fe‑Ni‑Co alloy components commonly used in hermetic assemblies, including:
- Housings and enclosures
- Lids and caps
- Sealing rings and seal carriers
- Frames and flanges
- Precision features for glass‑to‑metal and ceramic‑to‑metal seals
- Complex, thin‑wall components and small critical features for alignment, sealing, and assembly
Whether your design needs tight‑tolerance sealing surfaces, controlled burr conditions, or thin sections that resist distortion, KELTRYN is built around the challenges of machining Kovar for hermetic performance.
Built for Hermetic Sealing Performance
Machining Kovar for hermetic applications demands precision in every detail. Our processes are engineered to deliver reliable, repeatable results.
Heat Management & Work Hardening
Controlled cutting parameters minimize thermal stress and work hardening to maintain material stability and machinability.
Burr Prevention & Edge Control
Specialized toolpaths and finishing passes prevent burrs on critical sealing faces and edges, ensuring leak‑tight assembly surfaces.
Thin‑Wall Deformation Control
Fixture designs and low‑force clamping strategies preserve geometry in delicate, thin‑section features common in hermetic packages.
Dimensional Stability & Repeatability
Process controls and in‑process inspection ensure stable dimensions across prototypes and production batches for consistent hermetic interfaces.
Critical Surface Protection
Sealing and cosmetic surfaces are protected throughout machining and handling, avoiding nicks, scratches, and contamination.
Inspection & Quality Assurance
Comprehensive inspection support with dimensional reports, material certification, and lot traceability to meet your quality requirements.
