Explore our core engineering capabilities, integrating top-tier metal processing technologies with pristine anodised finishes.
Anodisation has transitioned from a basic anti-corrosion barrier into a foundational nanostructural engineering discipline. As global industries undergo rapid shifts toward lightweight structures, electric vehicle integration, and high-frequency communication enclosures, aluminum has emerged as the substrate of choice. However, raw aluminum lacks the surface hardness, electrical resistance, and chemical durability demanded by modern field environments.
Anodisation solves this mismatch through controlled electrochemistry, transforming the surface profile into an ordered, highly stable porous anodic aluminum oxide (AAO) layer. This film not only shields the component from environmental corrosion but also offers critical physical benefits, such as excellent thermal dissipation, high dielectric strength, and precise custom coloration.
Offers standard protective thickness (5-25µm), excellent dye absorption characteristics, and general corrosion resistance for architectural, automotive, and consumer goods.
Engineered for high-wear environments. Film thickness ranges from 25-100µm, yielding a surface hardness up to 600 HV to withstand abrasive wear in military, marine, and industrial applications.
A trusted, vertically integrated partner providing comprehensive metal processing and surface engineering solutions.
Established in 1996 as a family business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has developed into an owner-managed SME corporation. Located in the Ningbo Jiangbei Industrial Zone, our facility is within a 3-hour high-speed train ride from Shanghai International Airport, providing convenient logistics access for international clients.
With a total production area of 16,000 square meters and an additional 11,000 square meters of construction space, we maintain a complete technological infrastructure. Our staff of 130 includes 80 skilled production specialists and 50 experts dedicated to engineering, product design, quality control, and global supply chain management.
Our core mission is customer satisfaction through vertical integration. By handling structural production (such as hot forging, die casting, stamping, and multi-axis CNC machining) alongside post-treatment (anodisation, electropolishing, and complex assemblies) within a single factory, we eliminate transit oxidation, minimize lead times, and maintain single-point quality tracing.
