In the modern industrial arena, sub-micron tolerances and hermetic reliability are no longer optional characteristics; they represent the foundation of deep-tech scaling. As an industry-acclaimed supplier, Xinyunyang Precision Technology Co., Ltd. has, since its inception in November 2014, pioneered the convergence of material science and high-speed multi-axis CNC machining. We treat thermal matching, low coefficient expansion, and structural hermeticity as strategic technological pillars rather than merely mechanical tolerances.
By combining raw expertise in processing challenging low-expansion alloys such as Kovar (4J29), Titanium Grade 5, and Oxygen-Free Copper (OFC), we empower designers and defense procurement specialists to realize critical physical configurations. Our approach integrates rigorous thermal dissipation modeling with extreme surface finish controls to yield products that consistently outperform standard components under ultra-high vacuum (UHV), high frequency, and high thermal stress environments.
Fully tracked and authenticated batches ensuring zero-defect deliveries across every production shift.
As manufacturing landscapes globalize, high-precision machining has transitioned from a standard mechanical trade to a vital link in the technology supply chain. We provide critical foundational components enabling progress in AI, defense networks, and global communications.
Modern silicon platforms rely on hermetic micro-packaging to prevent trace degradation. We supply Kovar (4J29) hermetic package lids and micro-cavity shells with matching thermal coefficients. This guarantees perfect physical integration with silicon and ceramic structures, preventing catastrophic fatigue failures under fluctuating thermal loads.
Weight optimization, mechanical rigidity, and corrosion immunity are critical parameters in aerospace engineering. Our aviation-grade micro-filters and customized rotary joints are engineered to operate continuously in corrosive atmospheric environments, delivering superior fluid-flow integrity under extreme g-forces and thermal differentials.
High-power energy systems require ultra-low resistance interconnects to maintain high performance. By utilizing multi-axis CNC lathe machining on oxygen-free high-conductivity (OFHC) copper, we manufacture busbars, terminals, and heavy-gauge links that minimize internal electrical losses and limit thermal generation during rapid charging.
Unlike standard structural metals like aluminum or mild steel, specialized alloys require precise control of cutting tools and thermal expansion rates. We maintain an expert-level focus on Kovar (4J29), titanium, and engineering metals.

Kovar (4J29) is a nickel-cobalt-iron alloy specifically engineered to exhibit thermal expansion characteristics matching those of borosilicate glass and alumina ceramics. Over a wide thermal range (from cryogenic levels up to 400°C), Kovar's coefficient of thermal expansion (CTE) remains highly stable. This prevents mechanical stress and potential cracking in glass-to-metal (GTMS) or ceramic-to-metal interfaces during thermal cycling, ensuring reliable hermetic seals.
Our facility manages these challenges by maintaining stable feed rates, using rigid setups, and utilizing high-performance cobalt-based or carbide tooling equipped with advanced physical vapor deposition (PVD) coatings (like AlTiN). We also employ pressurized, high-volume flood cooling directly at the cutting zone. This effectively manages heat buildup and prevents the alloy from work-hardening under the tool edge.
We use high-sensitivity helium mass spectrometer leak detectors. Our testing protocols check for leakage rates down to 1x10⁻⁹ Pa·m³/s. This ensures the component can maintain a reliable hermetic seal in harsh environments, such as deep-space vacuum or high-pressure deep-sea installations.
