In the high-stakes domain of aerospace engineering, the reliability of a sensor is only as strong as its casing. Kovar (ASTM F15), an iron-nickel-cobalt alloy, has emerged as the industry gold standard for hermetic sealing applications. Its unique property—a coefficient of thermal expansion (CTE) that precisely matches borosilicate glass—ensures that sensor housings maintain structural integrity across the violent temperature fluctuations of space and high-altitude flight.
Modern satellites and UAVs demand "Smaller, lighter, and more powerful" (SWaP-C) components. Kovar casings allow for ultra-thin wall thicknesses while maintaining high structural rigidity and vacuum-tight seals.
From cryogenic temperatures in deep space to the intense heat of re-entry, Kovar provides a stable platform for delicate electronic components, preventing stress fractures and vacuum leaks.
Precision-machined Kovar housings act as an electromagnetic shield, protecting sensitive sensor data from the high-radiation environments common in orbital flight paths.
Global aerospace giants are shifting their procurement strategies towards partners who offer more than just manufacturing. The demand today is for Supply Chain Resilience and Digital Integration. China's precision manufacturing sector has evolved from a volume-based model to a sophisticated, Industry 4.0-driven ecosystem.
Utilizing AI-driven production systems to optimize CNC tool paths for difficult-to-machine alloys like Kovar, reducing lead times by up to 20% while ensuring zero-defect quality.
With localized clusters of raw material processing and surface finishing (such as gold or nickel plating), Chinese manufacturers like Xinyunyang offer a compressed lifecycle from prototype to mass production.
Adherence to ISO 9001 and AS9100 standards is now standard. Digital twins and real-time data tracking ensure every Kovar casing has a verifiable metallurgical pedigree.
Founded in November 2014, Xinyunyang Precision Technology has adhered to its initial intention of industry, sticking to the business principles of Integrity, Innovation, Cooperation, and Sharing. We have positioned ourselves as a premier Aerospace Sensor Kovar Casings Manufacturer with a deep focus on hermetic packaging technology.
The company focuses on Kovar precision processing technology as its core competitiveness, deeply cultivating the fields of semiconductors, optical communications, aerospace, medical devices, and new energy/military industry. We are committed to providing miniaturized, customized, and high-reliability metal packaging solutions to global customers.
A specialized workforce of over 100 people, with technical engineers accounting for 30% of the staff.
Core members have over a decade of experience in precision metal processing, pioneering composite techniques for Kovar and titanium alloys for AI and 5G sectors.
ISO 9001 certified quality management and intelligent scheduling systems ensure we remain a key supplier in the high-end global manufacturing chain.
Machining Kovar presents unique challenges that distinguish expert manufacturers from general machine shops. Kovar is known for being "gummy" and prone to work hardening. At Xinyunyang, we utilize advanced thermal stabilization cycles and specialized tool geometries to ensure the dimensional stability of every sensor casing.
Kovar (ASTM F15) matches the thermal expansion of borosilicate glass and ceramic materials. In aerospace, where temperature shifts are extreme, this prevents the glass-to-metal seals from cracking, ensuring a permanent vacuum-tight seal for the internal electronics.
We implement a multi-stage Quality Assurance protocol including ISO 9001 standards, 100% CMM (Coordinate Measuring Machine) inspection for critical dimensions, and helium leak testing for all hermetic packaging solutions.
Yes. Our flexible production scheduling allows us to support both low-volume prototyping and high-volume mass production. We specialize in miniaturized and complex geometries tailored to specific sensor designs.
We offer a range of aerospace-grade finishes, including electrolytic nickel, electroless nickel, and high-purity gold plating (per MIL-G-45204) to enhance solderability and corrosion resistance.
