Explore our elite portfolio of CNC components engineered for mission-critical industrial applications
Founded in November 2014, Xinyunyang Precision Technology Co., Ltd. has established itself as an industry pioneer in specialized metal fabrication. From our very inception, we have strictly adhered to the core business principles of Integrity, Innovation, Cooperation, and Sharing. Over nearly a decade of growth, we have continuously optimized our technical processes to fulfill the most demanding requirements of high-tech industries.
Our primary technological focus revolves around Kovar alloy precision processing. Kovar, with its unique coefficient of thermal expansion matching glass and ceramics, serves as the cornerstone for microelectronic packages. We deeply cultivate applications across high-reliability sectors, including semiconductors, optical communications, aerospace engineering, medical devices, and new energy systems. We provide highly customized, miniaturized, hermetically sealed metal package lids, housing, and components to advanced enterprises worldwide.
Deploying specialized engineering expertise and high-efficiency automation to ensure unmatched quality standards
We house a dedicated workforce of over 100+ highly trained technical professionals, where specialized research, development, and engineering personnel account for over 30% of our entire staff. This ensures that every component is analyzed for optimal manufacturability.
Our core technical leaders have been deeply engaged in precision metal processing for more than a decade. We specialize in complex processing technologies for exotic and challenging alloys such as Kovar (4J29), Invar, Titanium, and heavy-oxygen-free Copper. We anticipate tomorrow's needs in 5G, semiconductor, AI, and defense aerospace systems.
Operating under a strict ISO 9001 certified quality management system coupled with our digital MES intelligent scheduling, Xinyunyang has successfully optimized processing and supply routes. This structured workflow has accelerated regular order delivery efficiency by 15% to 20%, establishing us as a dependable global supplier.
China has evolved from a mass-production center into a global epicentre for high-end micro-machining. Sourcing CNC parts from precision clusters in China, particularly from specialized factories like Xinyunyang, offers unmatched supply chain advantages:
Complete Material Supply Chain: Our proximity to premium raw material suppliers allows immediate access to certified alloys like 4J29 Kovar, high-grade copper, stainless steels, and titanium. This shortens lead times for raw material procurement from weeks to days.
Technological Clusters: Guangdong's electronic and precision machining ecosystem provides us access to advanced electroplating services (such as high-purity gold plating, electroless nickel plating, and silver coating), heat treatment, and chemical passivating facilities. This enables us to deliver fully-finished, ready-to-assemble products under single-vendor responsibility.
Cost-to-Tolerance Ratio: By combining highly skilled programmers, robotic load-assistance, and advanced toolpaths, Chinese CNC manufacturers offer ultra-tight tolerances (down to ±0.005mm) at a fraction of the cost found in domestic markets.

Addressing modern engineering challenges through advanced metallurgy and processing innovations
With the rapid expansion of aerospace communications and fiber-optic networking, the demand for hermetically sealed housings has skyrocketed. Normal steel or aluminum cannot withstand cyclical thermal shocks because their expansion coefficients diverge from the internal silicon chips. Our specialized Kovar alloy CTE matching (4.7±0.2×10⁻⁶/℃) ensures perfect seals under extreme conditions (-65°C to +175°C).
High-frequency 5G enclosures demand extremely low dielectric attenuation and return loss. Our machined RF cavities support frequencies up to 40GHz with insertion losses limited to <0.26dB. Advanced internal surface finishes minimize surface roughness (Ra < 0.4μm), suppressing skin-effect signal losses in high-frequency applications.
Global brands prioritize ecological footprint metrics. Xinyunyang integrates sustainable fluid management systems that recycle 98% of CNC cooling oil. We minimize tool wear through digital toolpath simulation and implement non-hazardous plating chemistry to comply with global RoHS and REACH specifications.
Procuring precision CNC parts internationally requires meticulous planning and rigorous quality verification. Overseas purchasing managers must navigate material verification, production auditing, and logistics coordination. At Xinyunyang, we simplify this process through our standardized quality assurance workflow:
By implementing strict end-of-line inspections using 3D coordinate measuring machines (CMM) and helium leak detection systems, we ensure that every unit shipped is ready for integration.
Technical answers to critical questions about Kovar processing, CNC tolerances, and sourcing logistics
A: Kovar is an iron-nickel-cobalt alloy designed to exhibit a coefficient of thermal expansion (CTE) of approximately 4.7±0.2×10⁻⁶/℃ from room temperature to 450°C. This CTE matches hard borosilicate glasses and alumina ceramics. Under cycling temperatures, the materials expand and contract at the same rate, preventing cracks and ensuring seal integrity in high-reliability packages.
A: High-frequency RF components require exceptionally low surface roughness to prevent signal loss due to the skin effect. We utilize specialized tooling, optimal feeds/speeds, and custom finishing passes to achieve a surface roughness of Ra < 0.4μm. We also offer high-purity gold and nickel electroplating to protect the part from oxidation and optimize conductivity.
A: For high-precision parts, we consistently hit dimensional tolerances of ±0.005mm (5 microns) on our advanced multi-axis machining centers. For custom connectors and micro-groove optical lids, we maintain strict geometrical tolerances including flatness, concentricity, and parallelism.
A: We understand that designs undergo iterative changes. Our prototyping services (CNC rapid prototyping) enable rapid verification with the exact production materials. This ensures that electrical performance, thermal matching, and physical tolerances are verified before investing in high-volume production setups.
A: Our facility is ISO 9001:2015 certified. We audit our manufacturing operations to ensure compliance with RoHS (Restriction of Hazardous Substances) and REACH directives. This guarantees that all components, including surface coatings (such as gold or tin plating), are safe for global integration.
A: Prototyping typically takes 5 to 10 working days, depending on geometry and plating requirements. Standard production batches are completed within 3 to 4 weeks. With our digital scheduling system, we can reduce standard lead times by 15% to 20% to accommodate urgent customer timelines.
