Engineered to extreme tolerances. Select from our foundational structural assemblies, conflict-free hermetic packaging, and thermal management alloys.
Founded in November 2014, Xinyunyang Precision Technology has adhered to its initial intention of industry, sticking to the core business principles of Integrity, Innovation, Cooperation, and Sharing.
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 highly committed to providing miniaturized, customized, and high-reliability metal packaging solutions to global customers.
Our ultimate goal is to remain a significant hermetic package lids, Kovar alloy components, and precision parts supplier in China—and even worldwide—through persistent technological R&D and absolute reliability.
High-precision processing capability
Advanced technology and equipment
Strict quality control (ISO 9001)
Flexible customized services
Our core structural frameworks are optimized to streamline global industrial logistics and scale engineering efficiency.
The company has a professional team of more than 100 people, of which technical engineers account for 30%. This structure ensures rapid prototyping and immediate metallurgical consulting.
Core members have been deeply engaged in precision metal processing for more than ten years, continuing to explore composite processing technology for special metals (Kovar, titanium alloys), proactively mapping the next generation of RF & 5G housings.
Driven by an ISO 9001 certified quality system and intelligent production scheduling software, we have increased delivery efficiency for regular orders by 15%-20%, mitigating supply chain bottlenecks.
In modern electronic packaging, aerospace guidance systems, and medical diagnostics, the threshold for error has reached zero. As components shrink, materials such as Kovar alloy (ASTM F15 / 4J29), oxygen-free high-conductivity copper (OFHC), and titanium grades have transitioned from specialty requirements to foundational raw materials. Procuring from high-tier CNC turning and milling suppliers requires more than searching for the cheapest price per unit; it requires understanding the physical metallurgy, tool geometry, and quality management frameworks that determine whether an assembly will fail under vacuum, salt spray, or extreme thermal cycling.
"High-precision CNC turning and milling is not merely about removing excess metal. It is about stress-relief management, thermal coefficient synchronization, and surface topography optimization designed to prevent microscopic vacuum degradation over a 25-year mission lifespan."
Kovar is a nickel-cobalt-iron alloy specifically designed to match the thermal expansion characteristics of borosilicate glass. This properties makes it the absolute industry gold standard for glass-to-metal seals (GTMS) and hermetic packaging. However, Kovar's physical properties present severe manufacturing challenges:
At Xinyunyang, our engineers utilize advanced Dry-Machining protocols to bypass these limits. By utilizing specific positive rake angles, high-feed milling paths, and chemical-vapor deposited (CVD) diamond-like carbon coatings, we achieve a surface roughness of Ra < 0.3μm without introducing hydrogen embrittlement. This surface quality directly facilitates superior plating adhesion for subsequent gold or nickel plating processes.
While western buyers historically looked to China strictly for low-cost manual labor, the landscape in 2024 has completely shifted. Highly sophisticated hubs like Shenzhen, Suzhou, and Dongguan combine massive supply chain density with world-class automation.
1. Micro-Cluster Supply Ecosystems: Within a 50-kilometer radius of our production facility, we can source conflict-free raw materials, highly specialized plating vendors (electroless nickel, gold, silver), heat treatment facilities, and advanced coordinate measuring machines (CMM). This proximity dramatically reduces internal transportation lead times, permitting us to accelerate standard lead times by 15-20%.
2. Massive Technical Talent Influx: The Chinese educational system produces hundreds of thousands of specialized manufacturing engineers annually. As noted in our capabilities, 30% of Xinyunyang's 100+ personnel are dedicated technical engineers. This ratio ensures that complex RFQs receive deep engineering feedback rather than simple pricing templates.
3. Capital Investment in High-End Machinery: Factories in China are heavily invested in premium multi-axis machines, including Swiss-type sliding head lathes, 5-axis simultaneous machining centers, and wire-cut electrical discharge machines (EDM). This enables single-setup multi-operation machining, which eliminates the cumulative tolerance stack-up associated with multiple manual setups.
Precision CNC turning and milling operates at the core of several key global industries:
By addressing the macro-level solutions rather than treating parts as isolated orders, Xinyunyang acts as a strategic manufacturing partner. We advise our clients on minor design revisions (such as optimizing corner radius to match standard tool diameters) that cut cycle times by 30% while retaining structural integrity.

When purchasing custom CNC components, establishing a structured audit checklist is critical. Standard ISO certifications verify that a company follows documented procedures, but they do not guarantee that the supplier possesses the deep domain knowledge required to machine difficult metals like Kovar or high-conductivity copper without inducing hidden stress fractures.
To ensure complete alignment with international standards, procurement managers should focus on the following key operational parameters:
Verify that the supplier provides full Mill Test Reports (MTR) showing exact chemical compositions (especially the nickel-cobalt balance in ASTM F15 alloys) to ensure complete compatibility during subsequent glass sealing.
Modern global logistics require strict conformance with RoHS regulations and conflict-free supply chains. Ensure the partner operates with fully audited ESG certifications.
Verify that your machining partner manages advanced stress-relief annealing and controlled atmosphere treatment processes, which prevent structural cracking during thermal cycling.
Xinyunyang satisfies all these points. We work with certified, reputable metallurgy vendors to guarantee 100% material traceablity. By maintaining clear production tracking, we help our partners minimize procurement risks, optimize storage levels, and achieve faster time-to-market.

We routinely achieve surface roughness values of Ra < 0.3μm (and under specific circumstances, down to 0.15μm) through custom-engineered dry-machining protocols and optimized tool geometry. This surface finish ensures that hermetic sealing housings and military connector pins remain free from microscopic gas pockets, greatly improving seal reliability.
Every batch of Kovar (4J29) and high-purity copper processed in our facility comes with comprehensive raw material mill certificates. All incoming shipments are fully verified and traceable to ensure full compliance with RoHS, REACH, and international conflict-free mining regulations.
We primarily serve high-reliability and tight-tolerance sectors, including semiconductor manufacturing components, optoelectronic packaging, military RF connector assemblies, aerospace guidance systems, medical equipment housings, and clean-energy infrastructure.
Our custom ERP and smart scheduling system coordinates machine workloads, labor, and raw material availability in real time. This system minimizes transition times between setups and improves production efficiency by 15% to 20% for standard and recurring orders.
