High-precision manufactured components and surface finishes certified to global automotive and aerospace standards.
Founded in 1996 as a dedicated family enterprise, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has developed into a highly sophisticated, owner-managed SME corporation specializing in advanced metal fabrication and surface modification. Operating from the Ningbo Jiangbei Industrial Zone, our facility is strategically located within 3 hours of the Shanghai international transportation hub, providing an efficient global logistical pipeline.
Our expansive footprint features a 16,000 square meter production floor complemented by an additional 11,000 square meters of ongoing infrastructure development. XinYe supports a professional workforce of 130 experts, integrating 80 highly trained shop-floor technicians with 50 specialists in product development, quality control, manufacturing engineering, and corporate management.
We deliver an integrated suite of competencies including Precision CNC Machining, Aluminum Alloy Forging, Wax Die Stainless Steel Casting, Extrusion, Stamping, and Anodizing with Electropolishing (E-polish) surface treatments. Global procurement departments rely on our technology portfolio to supply critical assemblies to strict international quality standards.
An engineering exploration of our electrochemical passivation, oxide layer kinetics, and environmental compliance.
Anodization transforms the outer surface layer of aluminum alloys into an integration of aluminum oxide (Al₂O₃) via controlled electrolytic oxidation. By regulating sulfuric acid baths (typically 180-200 g/L) and current densities (1.0–1.5 A/dm²), we construct uniform barrier and porous layer structures. Proper chemical profiling prevents burning, micro-cracking, or powdery finishes across challenging copper-bearing 2xxx series and silicon-rich die-cast configurations.
We support both Type II (Military Specification MIL-A-8625) decorative/protective anodizing (film thickness 5–25 µm) and Type III Hard Anodizing (thicknesses exceeding 50 µm). Type III processes are operated at low temperature ranges (0°C to 5°C) to facilitate high-density barrier layer growth, producing surface hardness profiles up to 600 HV. This provides extreme wear resistance for slide rails, pistons, and components exposed to abrasive environments.
Post-anodic pores must be thoroughly sealed to ensure corrosion resistance. Our lines deploy hot water sealing (hydration process at >95°C), nickel acetate sealing for high dye-retention stability, and modern room-temperature cold sealing. Sealed components regularly survive 1000-hour ASTM B117 salt spray testing, protecting components in marine, aerospace, and safety gas detection systems.
We are actively transitioning toward eco-friendly alternatives to hexavalent chromium pretreatments and nickel-based sealing formulations. Our R&D team is refining trivalent chromium conversion coatings (TCP) and non-nickel organic seals to support our commitment to European RoHS/REACH compliance regulations, without compromising surface hardness or corrosion protection.
Cross-industry component engineering tailored for harsh operation conditions and critical safety approvals.
We manufacture explosion-proof and flameproof sensor housings, gas detection enclosures, explosive/toxic gas sensor bodies, and hydrant pit box kits. Our components undergo precise machining and chemical conversion treatments to resist corrosive atmospheres found in petrochemical installations and deep coal mines.
For high-altitude applications requiring low weight and high structural integrity, we supply Turbine Inlets, Fuel Line Brackets, Transmission Manifolds, and Aviation Fuel Hydrant Pit Box systems. We employ strict non-destructive testing (NDT) to prevent structural micro-fractures in critical flight control components.
Our contribution to the automotive sector encompasses powertrain transmission housings, high-efficiency cooling manifolds, and specialized electric bike (E-bike) components including structural connectors, extruded frames, tube profiles, and mechanical levers. We use lightweight aluminum forgings to support vehicle weight reduction targets.
Sanitation requires non-porous, chemically inert surfaces. We supply specialized components for tabletop cooking stoves and food-grade apparatus such as cream whippers. In these applications, electropolishing and controlled anodic oxidation prevent biological buildup and withstand aggressive cleaning regimens.
Modern global logistics require manufacturing partners with agile capacity scaling. XinYe operates under a default production schedule of 16 hours per day, 6 days a week. To support unexpected surges in global demand, our operation is structured to scale up to a full 24/7 continuous operation mode within a 30-day transition period.
We maintain dedicated land reserves surrounding our Ningbo plant to facilitate future warehouse and production floor expansions as customer demand grows. By sourcing domestic raw aluminum billets and forging dies, we shield our manufacturing lines from overseas material disruptions, ensuring stable pricing and reliable delivery schedules.

We operate under a strict quality management system to ensure traceablity from raw ingot down to the final anodized coating.
XinYe has earned both ISO 9001-2015 and SA8000 certifications. Our Quality Assurance department monitors critical physical and dimensional parameters using specialized inspection instruments:
Our structured production workflow maintains quality and efficiency from drawing receipt to international delivery.
Send your drawings (step, dwg, or pdf formats) containing dimensional tolerances, material selections, and surface finish requirements (e.g., anodizing type, E-polish). Our technical team will review manufacturing feasibility and calculate costs.
We source raw materials and manufacture physical sample prototypes using our tooling systems. Full dimensional testing reports (FQR) and raw material chemical certificates are provided for your inspection.
Customer examines prototypes in their target installations. Design modifications, assembly tests, and surface texture optimizations are finalized prior to high-volume production scheduling.
Upon sample approval, mass production is initiated. Quality control checks are performed throughout the extrusion, forging, CNC machining, and electrochemical anodization stages.
Components are assembled in our dedicated dust-free assembly workshop, packed in export-compliant protective packaging, and shipped by air or sea. All custom documentation is provided.
