Explore our comprehensive metal manufacturing portfolio. We integrate engineering, fabrication, and surface treatments under one roof.
Anodizing is no longer merely a decorative finish; it has evolved into a critical technological barrier essential for modern structural engineering. In today's aerospace, automotive, medical, and electronics ecosystems, surface modification technologies determine the operational lifespan and performance limit of lightweight components. Anodizing converts the aluminum substrate into a highly durable, corrosion-resistant, and aesthetically pleasing aluminum oxide ($Al_2O_3$) anodic layer.
As international markets increasingly prioritize energy efficiency and light-weight designs, aluminum alloys are replacing heavier ferrous metals. The global anodizing market is shifting towards tight-tolerance, thin-film hardcoat anodizing (MIL-A-8625 Type III) and environmentally conscious trivalent sealing techniques.
Ningbo Jiangbei XinYe Metal Works Co., Ltd. sits at the intersection of this global transformation, bridging advanced metal forging, high-precision machining, and structural electrochemical treatments to provide full vertical integration for global supply chains.
By controlling electrolyte concentrations, temperature variables, and current densities, we engineer anodic film layers ranging from decorative 5μm profiles to wear-resistant Type III hardcoats exceeding 50μm, displaying Vickers hardness up to 500 HV.

State-of-the-art electrochemical lines designed for Type II clear/colored anodizing, Type III hard anodizing, and electrochemical polishing (E-Polish) for stainless steel to satisfy pharmaceutical, food-grade, and optical cleanliness profiles.
Beyond simple production, we provide early-stage product development, tooling design, design-for-manufacturability (DFM) support, quality engineering, and global logistics coordination.
Selecting the appropriate anodizing parameters is critical to achieving target operational lifetimes. MIL-A-8625 Type II sulfuric acid anodizing is typically utilized for aesthetic coloring, atmospheric corrosion protection, and base preparation for painting, resulting in coating thicknesses between 1.8μm and 25μm.
In contrast, MIL-A-8625 Type III (Hardcoat) is performed under precise thermal control (near freezing temperatures of 0°C to 5°C) and higher voltage thresholds. This dynamic encourages rapid cellular growth of the aluminum oxide matrix while minimizing the dissolution rate of the oxide film. The resulting hardcoat layer (typically 25μm to 100μm) exhibits extreme wear resistance, excellent thermal insulation, and a low friction coefficient.
For non-mechanical components, sealing the porous anodic structure is critical to prevent corrosive agent ingress. We implement nickel-acetate sealing, hot DI water sealing, and modern chemical systems that achieve up to 1000 hours of Neutral Salt Spray (NSS) testing under ASTM B117 standards.

Key Equipment Profile:
High-tonnage friction press lines engineered to forge high-density aluminum alloy shapes with minimal flash and refined grain structures.
Our turning and milling assets feature multi-axis control to execute complex aerospace and industrial sensor contours in a single setup.
Our climate-controlled metrology laboratory is equipped with high-accuracy CMMs and video inspection tools to verify micro-scale geometric tolerances.
In addition to standard multi-axis centers, our turning capabilities feature the TIPAS MACHINE h65TMY. This platform provides rapid sub-spindle transfers and live tooling, allowing us to perform high-precision mechanical turning and threading on complex parts with minimal setups.
At Xinye, quality control is integrated throughout our manufacturing lifecycle rather than being a post-production check. We operate a structured quality management system certified to ISO 9001:2015 and SA8000 (Social Accountability) standards.
From verifying incoming aluminum alloy certificates to conducting final salt spray and dimensional checks, all inspection data is logged and traceable. The laboratory is maintained under strict climate controls to eliminate temperature-induced measurement deviations.
Our internal quality assurance team utilizes a comprehensive set of measuring and testing systems:
Verifies raw material chemical composition to prevent alloy contamination.
Calculates volumetric deviation on complex machining runs.
Provides fast, non-contact coordinate testing for complex flat profiles.
High-resolution zoom capability for micro-radius profiling.

Alloy selection directly affects anodizing outcomes. The 6000-series (e.g., 6061, 6063) offers excellent anodizing characteristics, yielding clear, uniform anodic layers. The 7000-series (e.g., 7075) is suitable for high-strength hardcoating, though it can exhibit a slightly darker, yellowish-grey tone. 2000-series alloys containing copper require specialized tank setups because copper can dissolve during processing, resulting in a less dense oxide layer that is best suited for functional Type III hardcoats rather than cosmetic finishes.
