1. Surface Prep: We clean the aluminum to remove grease, dirt, or oxides—critical for a smooth, even finish later.

2. Anodizing Core: The cleaned aluminum (as the anode) is dipped in an electrolyte (usually sulfuric acid). An electric current triggers a reaction, forming the oxide layer. We adjust voltage, temperature, and time to control layer thickness.

3. Optional Coloring: Choose between electrolytic coloring (metal salts for long - lasting hues) or dyeing (organic/inorganic dyes for vibrant, custom shades).

4. Sealing: The porous oxide layer is sealed with hot water or chemicals to lock in color and boost corrosion resistance.

• Durability Boost: The oxide layer resists scratches, corrosion, and wear—perfect for high - use items like automotive parts or outdoor fixtures.

• Design Flexibility: With a range of colors and finishes, it fits modern aesthetic needs, from sleek electronics to architectural accents.

• Eco - Friendly: No harmful heavy metals are used, and anodized aluminum is fully recyclable, aligning with sustainability goals.

• Cost - Effective: Its long lifespan reduces replacement needs, saving money over time.

• Multiple Anodize Types: Offer Type II (decorative, thin layer), Type III (hard anodize, for heavy - duty use), and chromic acid anodize (precision parts).

• Fast Turnaround: Streamlined processes mean we meet tight deadlines without compromising quality.

• Quality Checks: Every step is inspected to ensure the oxide layer, color, and finish meet your specs.
