Delivering high-reliability components to meet the requirements of today's most demanding physical computing and telecommunication applications.
Modern microelectronics, telecom interfaces, and high-frequency communication modules demand unparalleled physical stability. When operating at gigahertz frequencies or under immense temperature oscillations (e.g., aerospace deployment), standard metals fail due to mismatched thermal expansions. If the metal shell expands faster than the glass or ceramic signal pins, the seal cracks, causing instant vacuum loss and component failure.
Xinyunyang solves these challenges systematically by designing and manufacturing micro-engineered components with thermal coefficients matched closely to borosilicate glass and alumina ceramics. Our specialized Kovar alloy prototype machining allows developers to test hermetic packaging and mounting assemblies at micro-scales, ensuring rapid prototype-to-production cycles.
Furthermore, our copper, brass, and aluminum embedded housings enable optimal heat dissipation without sacrificing mechanical integrity, ensuring hardware systems can handle thermal challenges while preserving structural longevity.

Combining the reliability of Japanese Industrial Standards with China's unmatched smart manufacturing scalability
Global OEM procurement is no longer just about cost; it is fundamentally about supply chain resilience. Modern geo-economic conditions demand that parts suppliers provide robust raw-material sourcing, consistent quality assurance, and quick manufacturing turnarounds.
Operating from our high-tech hub in China, Xinyunyang has pioneered the transition to smart manufacturing (Factory 4.0). By using automated CNC cells integrated with real-time tool wear sensors, we maintain a zero-defect workflow across thousands of component batches. Our digital production scheduling engine optimizes spindle runtimes, reducing raw material waste and passing those cost benefits directly to our international clients.
Additionally, we maintain raw material stockpiles of certified Kovar, aviation-grade titanium, and specialized silicon brass. This protects our production timelines from global supply chain shocks, guaranteeing that our buyers receive consistent deliveries without unexpected delays or price spikes.
We execute absolute traceability by performing internal spectrometer audits and checking mill certificates on every incoming batch. We ensure that nickel, cobalt, and iron content fall exactly within JIS-tolerated specifications before manufacturing starts.
Our 3-axis, 4-axis, and multi-spindle Swiss CNC turning machines operate on optimized pathing profiles, achieving ultra-smooth surface finishes (Ra < 0.4μm) directly on the spindle, eliminating manual polishing stages.
Building the foundation for next-generation telecommunication systems, optical devices, and satellite micro-machining
As the digital landscape evolves toward 6G frequencies, autonomous driving AI models, and deep-space communications, the demand for high-reliability hermetic packaging and micro-machining is increasing exponentially.

In-depth insights regarding metallurgical parameters, custom machining capabilities, and order fulfillment
Kovar (composed of approximately 29% nickel, 17% cobalt, and 54% iron) is specifically designed to have a coefficient of thermal expansion (CTE) that closely matches borosilicate glass and alumina ceramics. This matching CTE prevents stress fractures and maintains airtight, hermetic seals across large temperature changes, which is vital for protecting sensitive electronics in aerospace, optical networks, and microelectronics.
Our compliance begins at the raw material stage, where we purchase and verify metals conforming to specific JIS classifications (such as JIS H2141 for specialized alloys or JIS G4303 for stainless steel). During and after manufacturing, we utilize high-precision metrology tools—including CMMs and optical comparators—to verify that all dimensions and thread structures conform strictly to the specified JIS tolerances.
Using our advanced Swiss-type lathes and multi-axis CNC machining centers, we routinely achieve dimensional tolerances as tight as ±0.002mm. We also inspect and verify surface roughness profiles, achieving finishes down to Ra 0.4μm without the need for manual secondary polishing, which ensures clean contact and seal integrity.
Our factory integrates an automated production scheduling engine. This system dynamically tracks machine runtimes, tool life, and material levels to optimize spindle workflows. By minimizing setup times and routing bottlenecks, we have reduced standard order delivery cycles by 15% to 20%, allowing us to respond quickly to changing client schedules.
Yes. We run a dedicated prototype machining service that allows engineering teams to validate custom designs with small-batch production runs.
