For over two decades, we have engineered critical components with uncompromising precision, integrating advanced metal processes and state-of-the-art anodizing treatments.
Founded in 1996 as an owner-managed family enterprise, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has evolved into a global leader in high-performance metallurgy. Our strategic production hub spans 16,000 square meters of production floor alongside an additional 11,000 square meters of construction area, situated in the Ningbo Jiangbei Industrial Zone. Our facility is situated within a convenient 3-hour high-speed rail connection to Shanghai International Airport.
With an active team of 130 professionals—including 80 specialized manufacturing staff and 50 experts dedicated to research and development, engineering, management, and quality control—we provide complete, vertically integrated solutions. We specialize in hot forging, precision CNC machining, wax die stainless casting, copper and plastic extrusion, stampings, and advanced electrochemical surface finishes (Type I, II, and III Hardcoat Anodizing and electropolishing).
As structural designs migrate toward lightweight, high-strength aluminum alloys, advanced surface treatment becomes paramount. Discover the macro trends shaping the global supply chain.
Ultra-high vacuum environments and semiconductor processing tools require Type III Hardcoat Anodizing with extremely low outgassing and high dielectric breakdown values. Critical components depend on these precise treatments to maintain reliability under extreme thermal stresses.
The industry is transitioning toward clean, chrome-free sealing agents and efficient acid recovery systems. Zero-liquid discharge policies push high-volume manufacturers to implement microfiltration and advanced wastewater treatments to keep up with green supply chain standards.
Automated dosing systems and real-time monitoring of anodizing baths maintain consistent oxide layer thickness, even across large production runs. This closed-loop quality control mitigates the variances associated with manual racking and current ramp configurations.
We complement our advanced surface treatments with heavy fabrication and precision engineering capabilities, ensuring complete processing under one roof.

Experience our manufacturing operations, robotic systems, and high-volume surface finish lines through video overviews.
Our processing lines handle everything from custom metal forging and multi-axis CNC machining to final electro-chemical anodizing and sub-assembly. We can scale our operation hours from a baseline of 16 hours a day, 6 days a week to full 24/7 continuous production within 30 days of client request.
Our machining floor utilizes premium multi-spindle turning centers like the TIPAS h65TMY, engineered to maintain tolerances of under 0.001mm on complex geometric profiles before surface anodization.
Explore Core FeaturesWe maintain a comprehensive internal testing laboratory to verify structural, dimensional, and chemical compliance at every stage of production.
At Ningbo Jiangbei XinYe Metal Works, quality is our absolute priority. We operate a dedicated, climate-controlled testing lab with advanced metrology equipment to inspect raw materials and finished parts. By maintaining complete compliance with ISO 9001-2015 and SA8000 certifications, we ensure every part is traceable, verifiable, and consistent.
Our quality control process starts at goods receipt with spectrographic analysis of incoming billets. It continues through the anodizing bath, where thickness and sealing quality are measured, and concludes with final inspection. This closed-loop process ensures that every shipment meets strict international standards.
Our high-precision manufacturing services and custom anodizing treatments support safety-critical systems across global industries.

How Ningbo Jiangbei XinYe Metals is investing in advanced surface science, automation, and green manufacturing technologies.
Developing thin-film anodizing options to serve as paint pre-treatments, replacing hexavalent chromium coatings. This provides excellent corrosion protection with a minimal footprint, helping clients meet environmental compliance goals.
Integrating chemical sensing arrays to monitor bath concentrations, dissolved aluminum levels, and temperature profiles in real time. This ensures consistent layer thickness and prevents surface pitting during large runs.
Installing advanced acid purification units to reclaim spent acids and reduce wastewater volume. This closed-loop design helps minimize overall material costs and reduces the environmental footprint of our operations.
Our commitment extends beyond engineering precision to cultivating long-term partnerships built on three key pillars:
Trust: We prioritize your specifications, aiming to exceed expectations in every production run. We take responsibility for every project, from custom design to final logistics.
Professionalism: We bring dedication and an improvement-focused mindset to every part we make. Our engineers participate in continuous training to maintain technical expertise.
