Explore our diverse metalwork capabilities: from complex stamping and deep drawing to state-of-the-art aluminum hot forging and anodizing treatments.
In contemporary structural engineering, raw aluminum alloys are insufficient to handle extreme environments without targeted surface treatments. Anodizing is not merely a superficial coating; it is an electrochemical conversion process that transforms the outer layer of aluminum into a robust, integrated aluminum oxide (Al₂O₃) coating. This oxide layer is fully integrated with the underlying substrate, ensuring it cannot peel, flake, or chip, while offering superior corrosion inhibition, wear protection, and dielectric insulation.
As a premier global manufacturing partner, Ningbo Jiangbei XinYe Metal Works Co., Ltd. (established in 1996) integrates advanced CNC machining, hot forging, lost wax casting, and stamping with specialized chemical surface treatments, including precision sulfuric acid anodizing and electro-polishing. Strategically located within the Ningbo Jiangbei Industrial Zone, just three hours from Shanghai International Airport, XinYe offers fully integrated vertical manufacturing solutions to meet the demands of global tier-one supply chains.
With a dedicated workspace spanning 16,000 square meters of production floor and an additional 11,000 square meters of facilities under construction, our team of 130 highly trained professionals (including 80 specialized production technicians and 50 dedicated R&D, engineering, and quality specialists) handles components from initial chemical composition verification through custom forging and precision machining to final surface treatment, ensuring a smooth, single-source manufacturing workflow.
Tailoring chemical and electrochemical surface modifications to meet the stringent demands of aerospace, automotive, medical, and defense sectors.
Operating at temperatures of 15-21°C and current densities of 1.0-1.5 A/dm², this process produces oxide layers from 5μm to 25μm. Perfect for structural automotive components, connector kits, levers, and electronic housings requiring corrosion resistance combined with custom decorative coloring.
Conducted at freezing levels (0-5°C) and higher voltages, this process generates hard, wear-resistant coatings up to 100μm thick. It is ideal for heavy-duty applications such as turbine inlets, cylinder bores, and slide guides exposed to extreme friction and corrosive conditions.
Electrochemical polishing of cast and forged stainless steel parts removes microscopic peaks, reducing surface roughness to under Ra 0.2. Crucial for food processing machinery, sanitizable medical systems, and explosive-gas detection enclosures.
| Property / Characteristic | Type II Sulfuric Anodizing | Type III Hardcoat Anodizing | Electro-Polishing (Stainless Steel) |
|---|---|---|---|
| Typical Film Thickness | 5 – 25 microns (μm) | 25 – 100 microns (μm) | Microscopic surface smoothing (no coating) |
| Microhardness (HV) | 200 – 350 HV | 400 – 600 HV | Increases surface hardness slightly via passivated oxide |
| Primary Application | Enclosures, brackets, cosmetic components | Wear components, hydraulic actuators, pistons | Medical instruments, food processing parts |
| Corrosion Resistance | Excellent (336+ hrs salt spray test) | Superior (1000+ hrs salt spray test) | Highly passive layer, stops localized pitting |
How our multi-disciplinary engineering shop converts engineering designs into certified metal components under strict quality control.
Review of 2D/3D CAD files (STEP, IGES, DWG) for DFM optimization, choosing the correct alloy and anodizing specifications.
Hot forging (presses from 300t to 1000t), high-pressure die casting, precision stamping, or CNC machining to precise tolerances.
Alkaline degreasing, acid etching, and de-smutting to prepare a clean surface for anodizing or polishing.
Controlled anodizing bath under strict temperature and current settings, followed by chemical sealing or organic dyeing.
Verification using CMM, spectrum analysis, film thickness gauges, and salt spray testing before final dispatch.
At Ningbo Jiangbei XinYe, we operate under the core philosophy: "Quality is the lifeline of engineering." As an ISO 9001:2015 and SA8000 certified manufacturer, we maintain traceability records from incoming raw materials to final shipping. Our laboratory is equipped with state-of-the-art testing equipment to ensure parts match your exact engineering requirements.
Guarantees the chemical purity of incoming raw aluminum, stainless steel, and brass alloys to verify chemical compositions before production begins.

Watch our heavy forging equipment, precision machining, and metal finishing lines in action.
Our facility operates 16 hours a day, 6 days a week, and is ready to scale to 24/7 continuous production within 30 days if required. Learn about our integrated stamping, hot forging, casting, and finishing lines.
See our high-speed precision equipment (including TIPAS h65TMY systems) machining complex structural components to tight tolerances before they head to surface finishing.
The metal finishing industry is undergoing shift driven by global environmental policies, specifically REACH, RoHS, and EPA clean air/water mandates. Traditional processes, such as chromic acid anodizing (CAA) that use toxic hexavalent chromium (Cr⁶⁺), are being phased out in favor of eco-friendly sulfuric acid anodizing (SAA) and tartaric sulfuric acid (TSA) formulations.
As a socially responsible manufacturer certified under SA8000, Ningbo Jiangbei XinYe has invested in state-of-the-art wastewater purification and air filtration systems. This keeps our anodizing processes compliant with strict international environmental regulations, ensuring no disruption in shipments to Europe or North America.
Looking ahead, our technical team is expanding into micro-arc oxidation (PEO/MAO) to produce thicker, more heat-resistant coatings on aluminum and magnesium alloys. Additionally, we are integrating automated chemical dosing and robotic handling systems into our anodizing line, ensuring consistent surface finishes on every production run.
