At Xinyunyang Precision Technology Co., Ltd. (founded in November 2014), we have dedicated ourselves to mastering the complex physical and mechanical challenges of high-end CNC machining. Over a decade of rigorous engineering development has positioned us at the frontier of custom hermetic packaging lids, Kovar alloy frames, and precision multi-axis components.
Traditional materials often fall short under thermal stress and aggressive environments. Our work with controlled-expansion alloys, notably Kovar (Fe-Ni-Co alloy, ASTM F15), solves one of the most persistent problems in electronic packaging: thermal expansion mismatch. By meticulously controlling the chemistry and microstructural deformation during multi-axis milling, we achieve components that match the Coefficient of Thermal Expansion (CTE 4.7±0.2×10⁻⁶/℃) of borosilicate glasses and alumina ceramics. This provides an absolute gas-tight, hermetic seal essential for fiber optic networks, spaceborne radar systems, and military-grade power modules.
Our facility houses over 100 dedicated technical operators and metallurgists, with 30% of our workforce acting as senior development engineers. This ensures that every drawing, CAD model, or custom specification sheet receives thorough DFM (Design for Manufacturability) analysis prior to production.
Our senior engineering core has spent more than ten years developing processing models for refractory, abrasive, and delicate alloys. We continuously expand our capabilities into composite processing of special metals such as Titanium alloys, Invar, Kovar, and oxygen-free copper, keeping pace with 5G, artificial intelligence, and new energy vehicle industries.
Operating under a strict ISO 9001 Quality Management System, Xinyunyang has pioneered an intelligent digital production scheduling system. This custom ERP platform connects our multi-axis CNC milling centers directly with quality control inspections, shrinking typical lead times for regular custom orders by 15% to 20%.
One of the common errors in precision hardware sourcing is selecting a generic milling machine shop for highly specialized materials like Kovar or Invar. Standard CNC machining operators often approach these alloys with standard speeds, feeds, and coolant mixtures. However, Kovar exhibits strong work-hardening characteristics. If machined using improper tool pathways or worn carbide tooling, the material experiences localized heating and mechanical stress, altering its crystal structure.
This crystalline shift can cause a drift in the CTE, leading to micro-cracking at glass-to-metal interfaces during subsequent glass sealing processes. At Xinyunyang, our engineers utilize proprietary milling techniques that maintain structural homogeneity. We balance tool engagement angles, utilize specialized synthetic lubricants, and apply precise stress-relief annealing procedures to ensure the material retains its physical properties throughout its operational lifespan.
Western defense, aerospace, and medical sectors demand clear proof of origin. Our supply line of 4J29 Kovar, titanium, and other raw metals is strictly validated back to smelters certified by the Responsible Minerals Initiative (RMI). We offer complete ESG documentation, helping our clients easily pass stringent supply chain audits.
As wireless systems transition to millimeter-wave frequencies, signal loss becomes a primary challenge. Our CNC milled Kovar 5G enclosures feature ultra-low insertion losses (IL < 0.26 dB at 40 GHz). They provide robust electromagnetic shielding while ensuring perfect thermal dissipation for powerful RF transceivers.
To bridge the gap between design concepts and scale production, we offer high-fidelity localized engineering assistance. We review customer technical drawings, suggest manufacturing improvements, and deliver first-article inspection (FAI) reports within days, accelerating product development cycles.
