In the demanding world of advanced manufacturing, creating a reliable and hermetic seal between glass and metal remains a critical challenge, particularly in industries like aerospace, medical devices, and highvacuum electronics. Success hinges on one crucial factor: the precise machining of specialized alloys, with Kovar standing out as the premier choice. Our expertise in CNC machining Kovar positions us as a vital partner for your most critical glasstometal seal (GTMS) applications.
cnc machining center Kovar, an ironnickelcobalt alloy, is uniquely engineered to have a coefficient of thermal expansion (CTE) that closely matches that of borosilicate glass and certain ceramics over a wide temperature range. This matching CTE is the cornerstone of a successful seal. During the heating and cooling cycles of the sealing process, both the metal and glass expand and contract at nearly identical rates. This prevents the buildup of thermal stress that would otherwise crack the glass or compromise the hermeticity of the seal. However, Kovar's same properties that make it ideal for sealing—its unique workhardening rate and tendency to workharden—make it a challenging material to machine, requiring specialized knowledge and equipment.
This is where our precision CNC machining capabilities become indispensable. We understand that the integrity of a GTMS component is only as good as the precision of its machined features. Our advanced CNC mills and lathes, equipped with specific tooling and coolant strategies, are configured to handle Kovar's intricacies. We achieve the tight tolerances, superior surface finishes, and complex geometries required for components such as headers, feedthroughs, and sensor housings. Every cut is programmed to minimize stress and deformation, ensuring the final part is perfectly suited for the subsequent glassing process.
Furthermore, our service is a comprehensive, onestop solution. We don't just machine the part; we provide the full spectrum of valueadded services. This includes expert material sourcing to guarantee the authenticity of the Kovar alloy, meticulous postmachining cleaning to remove all contaminants, and secondary operations like welding or brazing. By managing the entire process, we ensure consistency, quality, and a faster timetomarket for your products.
Choosing our company for your CNC machined Kovar components means investing in reliability. We empower innovators in the medical, aerospace, and telecommunications sectors to develop smaller, more powerful, and more durable devices with confidence. Partner with us to ensure your glasstometal seals are built on a foundation of precision and expertise, driving your products' performance and your business growth.
