Engineered Metal Components Crafted with Global Standards and High-Precision Technology
Established in 1996 as a family-owned metal fabrication business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has evolved into a leading owner-managed SME corporation specializing in advanced metallurgical processes. Nestled in the heart of the Ningbo Jiangbei Industrial Zone, our modern facilities are situated within a highly integrated logistics node, only 3 hours from Shanghai International Airport via high-speed train networks.
With a total operational footprint spanning 16,000 square meters of specialized production floor and an additional 11,000 square meters of ongoing engineering construction, we manage a workforce of 130 highly specialized personnel. This includes 80 skilled production specialists and a dedicated 50-person administrative, design, engineering, and quality assurance team.
We pride ourselves on offering comprehensive manufacturing integration, ranging from precision CNC machining, hot aluminum alloy forging, wax die stainless casting, to metal extrusion, stamping, and premium finishing (including color-matching anodizing and electro-polish surface treatments).
How Modern Aerospace-Grade Investment Casting Elevates Architectural & Industrial Bronze Sculptures
Lost wax casting, or investment casting, is a time-tested process modernized by automated shell coating, climate-controlled curing rooms, and high-purity alloy furnaces. For bronze sculptures and specialized industrial bronze components, this process provides unparalleled design freedom, allowing for complex geometries, thin walls, and smooth surfaces without draft angles.
We work with silicon bronzes, manganese bronzes, and custom copper-base alloys to achieve high structural stability, superior fluidity in mold cavity filling, and excellent corrosion resistance. Each batch is validated using a premium Italian GNR Spectrum Analyzer to ensure elemental consistency.
Using precision aluminum toolings, we inject structural waxes with minimal volumetric contraction rates. This guarantees that initial geometries replicate the original artwork or engineer's 3D CAD design within tight tolerances, eliminating excessive final manual grinding and material wastage.
To meet the diverse demands of global enterprises, our surface finishing department delivers custom patination, electro-polishing, chrome plating, and physical vapor deposition (PVD). This gives both artistic sculptures and heavy-duty industrial components high aesthetic value and chemical protection.
Navigating Strict Technical Standards and Global Environmental Regulations
We cast and machine bronze components to exact international specifications: ASTM B584 (Standard Specification for Copper Alloy Sand Castings), EN 1982 (Copper and Copper Alloys - Ingots and Castings), and equivalent JIS/DIN norms. This guarantees seamless compatibility inside heavy machinery, fire hydrant installations, and marine systems.
Holding the prestigious SA8000 Certification, we comply with international standards regarding labor conditions, human rights, and workspace safety. This status makes us a low-risk, ethical manufacturing partner for tier-1 automotive manufacturers and public municipal procurement bodies.
Using robust container packaging and vapor corrosion inhibitors (VCI), we protect parts from maritime moisture. All shipping operations are handled by logistics professionals, providing complete custom clearance documents, Certificates of Origin, and SGS-conforming material analyses.
Ningbo is historically recognized as the powerhouse of China’s high-precision metal casting and CNC machining industries. Operating from our industrial zone gives us access to a dense cluster of specialized alloy suppliers, secondary toolmakers, heat treatment operations, and surface patination experts.
This localized cluster reduces logistics costs and raw material lead times. Supported by state-of-the-art infrastructure, we can transition from default 16-hour shifts to full 24/7 continuous operations within 30 days to meet massive production spikes for large-scale municipal architectural bronze installations or automotive contract orders.
Located near the Ningbo-Zhoushan Port, the world's busiest port by cargo tonnage, we offer direct ocean freight to North America, Europe, and Asia. Crucially, this is supported by a 3-hour high-speed train link to Shanghai International Airport, allowing fast physical transport of pre-production samples and facilitating audits by international buyers.
Five Essential Stages of Quality-Driven Production
Detailed engineering drawing evaluation, CAD model alignment, alloy confirmation, production planning, and scheduling.
Precise tool making, wax pattern injection, shell building, dewaxing, pouring, and dimension testing verification.
We ship samples directly to our clients. Mass production proceeds only after formal structural and finish approvals.
Continuous pouring, automatic shaking out, shot blasting, multiaxial CNC machining, and intermediate quality checks.
Packaging in custom wooden boxes, one-year comprehensive warranty, and support on secondary assembly processes.
Heavy Investment in Imported Japanese Machinery & Precision Forging Equipment
To support hot metal operations, our forge features friction presses ranging from 300 to 1,000 tons of compression force, column hydraulic press installations (100 to 630 tons), and punching press lines (5 to 250 tons).
Our machining department is equipped with 4-axis CNC machining centers, high-accuracy CNC turning lathes, and advanced milling machines to achieve tolerances down to 0.001mm.
We feature a large assembly facility to assist clients in putting together multiple components (e.g., combining castings, machined pins, stamps, and spring assemblies) before shipping.
Ensuring Defect-Free Bronze and Stainless Casting Deliveries Under ISO 9001-2015 Guidelines
At Xinye, quality is life. Material properties, dimensional tolerances, and structural density are monitored at every phase. Our in-house testing laboratory features the latest measuring devices to check dimensions and detect internal micro-porosity.
