Explore our premium metal manufacturing capabilities, engineered for absolute dimensional accuracy and top-tier industrial performance.
Ningbo Jiangbei XinYe Metal Works Co., Ltd. was established in 1996 as an owner-managed SME corporation. Located in the Ningbo Jiangbei Industrial Zone, our facility is within a convenient 3-hour commute from Shanghai International Airport via the high-speed rail network.
Spanning a total production floor of 16,000 square meters, with an additional 11,000 square meters under construction, XinYe is a hub of advanced manufacturing. Our dedicated workforce of 130 employees includes 80 skilled production professionals and 50 experts specialized in product development, engineering, quality control, and management operations.
We offer professional engineering qualifications across CNC machining, aluminum alloy hot forging, lost wax stainless casting, metal extrusion/stamping, and comprehensive Natural Anodising & E-polish surface treatments.
A comprehensive overview of electrochemical oxidation mechanisms, layer properties, and durability metrics for global industrial applications.
Natural anodising (frequently referred to as clear anodising) is an electrochemical process that transitions the raw aluminum surface into a decorative, durable, and corrosion-resistant anodic oxide finish. By utilizing a sulfuric acid bath with precise electrical currents, we structure a controlled oxide layer ranging from 5 to 25 microns, preserving the metallic texture while offering heavy-duty protection.
While Type II Natural Anodising provides excellent aesthetics and corrosion resistance for consumer goods, medical devices, and architectural parts, Type III Hard Anodising provides a thicker layer (up to 50+ microns). This increases wear resistance and micro-hardness (up to 450 HV) for demanding automotive transmission and aerospace gear components.
Post-anodic hydration is crucial. We employ advanced hydrothermal and nickel acetate sealing methods to close the microscopic porous structure. This process enables our natural anodised components to successfully withstand up to 336 hours of neutral salt spray testing (ASTM B117) without signs of pitting or surface breakdown.
For global procurement departments looking to source components from China, adhering to standard parameters ensures perfect physical fitment and operational longevity. The table below lists standard operational parameters monitored closely on our production lines:
| Parameter | Standard Range | Test Standards | Application Significance |
|---|---|---|---|
| Oxide Film Thickness | 5µm - 25µm (Up to 50µm for Hard Coat) | ISO 2360 / ASTM B244 | Corrosion barrier and electrical insulation depth. |
| Surface Hardness | 250 HV - 450 HV | ISO 4516 / ASTM E384 | Resists scratching, frictional wear, and abrasive damage. |
| Sealing Quality | Mass Loss < 30 mg/dm² | ISO 3210 / ASTM B136 | Assures the pore structure is locked against corrosive elements. |
| Salt Spray Performance | 96 hrs to 336 hrs (dependent on alloy) | ISO 9227 / ASTM B117 | Guarantees performance in high-humidity or marine applications. |
Balancing price efficiency, material compliance, and geopolitical supply chain security in modern industrial manufacturing.
Procurement teams from Europe, North America, and other global regions face continuous pressure to lower component costs while meeting high standards of material traceablity and environmental compliance. Our factory addresses these needs by combining low China manufacturing overheads with European-level management practices.
By utilizing a highly integrated supply chain in the Ningbo industrial sector, we purchase raw materials (such as 6000 and 7000 series aluminum alloys) directly from domestic smelters. This allows us to offer transparent pricing models and protection against volatile commodity price fluctuations.
Modern manufacturing demands agility. Geopolitical disruptions and changing demand patterns require factories that can rapidly scale up production volumes. XinYe operates 16 hours a day, 6 days a week, and has the capacity to transition to a 24/7 continuous operation within 30 days.
To support ongoing customer growth, we actively invest in our machinery and facilities. We maintain open land adjacent to our existing site for physical expansion, ensuring we can scale up production line footprints to meet long-term strategic agreements.
We are located in Ningbo, Zhejiang province. Our facility is within 3 hours of Shanghai via the high-speed rail network, enabling convenient on-site inspections for international QA teams.
From deep under the earth to the upper atmosphere, our natural anodised and precision-machined metal components deliver performance when it matters most.
Providing transmission components, turbine inlets, and complex aviation fuel hydrant pit boxes. Our natural clear anodising ensures excellent surface preservation, prevents oxidation, and maintains critical tolerances.
Manufacturing drive-train components and E-bike critical connection parts (levers, structural connectors, and tubes) that combine low weight with high wear resistance to optimize vehicle performance.
Machined parts for fire and gas safety detection systems in mining and petroleum extraction. These parts operate in harsh, explosive environments where zero-spark, corrosion-proof surfaces are vital.
Components for commercial kitchen and food packaging machinery, such as cream whippers and tabletop cookers. Non-toxic, easy-to-clean natural anodised coatings meet FDA food contact regulations.
Our core production equipment is imported from Japan, providing high structural accuracy and consistent repeatability across large production runs.
Featuring friction press machines with press forces from 300 to 1000 tons, and column hydraulic machines from 100 to 630 tons. This setup yields high-density structural components with optimized grain flow.
Equipped with 4-axis control CNC machining centers, high-accuracy lathes, and milling systems. This machinery achieves tolerances within a few microns for complex, three-dimensional geometry profiles.
An in-house laboratory equipped with CMM, spectrometer, and video measurement systems. We inspect every batch of incoming raw materials and outbound finished products.

How we are evolving our operations to support greener processes, automated logistics, and Industry 4.0 standards.
Traditional anodising lines generate acid mist and wastewater that require treatment. To minimize our footprint, we are rolling out a zero-discharge water recycling system. This setup purifies and recycles rinse water back into the baths, reducing water usage by over 60%.
To improve part consistency and safety, we are integrating robotic loading arms into our high-volume press and CNC lines. This automation reduces human error in cycle times and ensures consistent contact during anodising.
We are deploying IoT-connected sensors to monitor critical anodising parameters—including temperature, current density, and chemical concentration. This data is logged continuously, providing a complete digital record for batch verification.
At XinYe, quality is core to our operations. We maintain a strict quality control system from raw material validation to final product dispatch.
Our facility is certified to ISO 9001:2015 (Quality Management Systems) and SA8000 (Social Accountability Standards). This dual certification demonstrates our commitment to both engineering quality and ethical manufacturing operations.
