Discover our core industrial processes utilizing advanced tooling and premium natural anodizing surface treatments designed for long-term reliability.
Natural Anodizing (often called clear anodizing) is an electrochemical passivation process that alters the surface chemistry of aluminum alloys. By placing the aluminum components in an acid electrolyte bath (typically sulfuric acid, H2SO4) and running an electric current, oxygen ions are released from the electrolyte to fuse with aluminum atoms, producing a highly ordered, microscopic layer of Aluminum Oxide (Al2O3).
Unlike painting or electroplating, which adds a topical layer that can peel or chip, natural anodizing integrates directly with the underlying aluminum substrate. This yields a highly durable finish that is completely non-reactive, preserves the natural metallic silver luster, and offers superior hardness (up to 300 HV for standard Type II anodizing, and even higher for Type III hardcoat anodizing).
As a leading wholesale manufacturer, our anodizing facility ensures strict control over parameters like current density, temperature, and chemical concentrations. This minimizes variations in film thickness, giving you consistent optical properties and uniform thickness across all production batches.
A premier owner-managed SME corporation specializing in advanced metal forming and precision surface finish engineering since 1996.
Founded in 1996 as a family business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has grown into a highly specialized, owner-managed manufacturer. Located in the Ningbo Jiangbei Industrial Zone, our facility is strategically positioned for global trade, reachable within 3 hours from Shanghai International Airport via the high-speed train network and close to the world-class deepwater Port of Ningbo-Zhoushan.
Our facility spans 16,000 square meters of modern production floor space, with an additional 11,000 square meters under construction to support our ongoing expansion. We employ a dedicated team of 130 professionals, including 80 front-line production staff and 50 experts specialized in product development, quality control, precision engineering, and global supply chain management.
The strategic supply chain advantages of partnering with Ningbo Jiangbei XinYe Metal Works Co., Ltd.
Unlike third-party anodizing shops, we manage the entire value chain in-house. We run stamping, hot forging, lost wax casting, precision CNC machining, and natural anodizing under one roof. This guarantees continuous quality control and faster lead times.
Our standard production schedule runs 16 hours a day, 6 days a week. For high-volume projects, our flexible operations team can ramp up to full 24/7 continuous operations within 30 days. This makes us highly responsive to sudden shifts in market demand.
We rely on high-precision Japanese fabrication equipment alongside state-of-the-art metrology tools. Our quality department uses Coordinate Measuring Machines (CMM), GNR Spectrum Analyzers, and Video Measuring Systems to inspect and verify every batch.
Engineered components built for extreme environments, heavy wear, and high safety standards.
We manufacture custom natural anodized housings and components for oil, gas, and mining industries. Key products include fire and gas safety detection kits, flame sensors, explosive gas detectors, and hydrant pit box enclosure kits. These components are natural anodized to withstand harsh weather, salt spray, and corrosive environments.
In aerospace, weight reduction and surface protection are critical. We produce turbine inlets, transmission parts, and aviation fuel hydrant pit boxes using premium aluminum alloys. The natural anodizing process creates a highly resistant barrier against fuel degradation and atmospheric wear.
We supply lightweight automotive transmission components and E-bike parts, such as connectors, structural tubes, and control levers. Natural anodizing improves surface hardness, reduces friction, and prevents oxidation from road salt and moisture.
Anodized aluminum is completely non-toxic and FDA-compliant. We manufacture whipping siphon components (cream whippers) and tabletop cooking stove assemblies that require heat resistance, chemical stability, and easy cleaning.
Our capabilities include producing feed rollers and chipper cutter discs using robust alloys like Q345B, 42CrMo, and NM400. Anodized guides and adjacent structures maintain low friction and resist wear during heavy wood-chipping and processing operations.
Inside our manufacturing facility, featuring advanced high-force presses, multi-axis CNC centers, and automated tooling.
Our continuous capital investments ensure we maintain the capacity to expand and adapt machinery lines to meet custom buyer profiles and high-volume orders.








For Ningbo Jiangbei XinYe Metal Works, Quality is life. We operate an advanced quality assurance system, backed by ISO 9001-2015 and SA8000 certification. This structured process provides clear accountability and full material traceability, from raw metal stock to the final shipment.
To maintain dimensional accuracy and finish quality, our QC department relies on advanced testing equipment:
Our ISO 9001:2015 and SA8000 certifications demonstrate our focus on technical precision and socially responsible, compliant factory management. We undergo regular audits to ensure consistent quality for all international industrial buyers.
From initial drawing confirmation to final delivery, we maintain a transparent, highly controlled production flow.

Customers provide engineering blueprints and project specifications. We review design tolerances, discuss material choices, and align on initial pricing and production lead times.

We review technical drawings, calculate tool paths and raw material costs, produce prototype samples, and provide a full dimensional test report and material certificate.

We send sample parts to the client for validation. Our engineering team refines parameters based on direct feedback before signing off on mass production.

Upon sample approval, we initiate mass production. Structured quality checkpoints monitor progress, and finished parts are packaged in protective export-grade materials.

We offer a one-year warranty on manufacturing defects, starting from the delivery date, backed by our dedicated assembly workshop and engineering team.
