Aluminum Anodizing Film Custom Multiple Thickness High Wear & Salt Spray Resistant for Construction Auto 3C Parts, Dyeing & Electrolytic Coloring Available, Stable Coating Process from Full Lines

Supported by complete automatic oxidation production lines of MEIAL Technology, we customize oxide film ranging from 5μm to 120μm, covering decorative anodizing, hard anodizing and MAO ceramic coating. Compliant with GB/T 5237 & MIL-A-8625 standards, uniform coating without thin areas. Matte, bright, satin surface optional, excellent corrosion & UV resistance. Compatible with 6061/6063/7075 cast aluminum, magnesium & titanium alloy. One-stop solution including oxidation equipment & mature coating technology.

MEIAL oxide films are manufactured with mature processes matched to our self-developed automatic horizontal, vertical, manual and mini MAO micro arc oxidation production lines.

Coordinated with SCR rectifier power supply, PLC automatic traveling crane, plate heat exchanger constant temperature control and tank circulation filtration system, our equipment precisely regulates film growth speed and controls thickness tolerance within ±1μm across whole workpieces.

We provide three mainstream coating systems: decorative anodizing film, hard wear-resistant anodizing film and MAO ceramic oxide film with customizable full-range thickness. Multiple surface finishes are available: natural silver, organic dye coloring (bright gold, red, blue, green), electrolytic coloring (champagne gold, bronze, matte black). Combined with pure water sealing & nickel acetate medium-temperature sealing technology to seal micropores, the film greatly improves salt spray and UV resistance. Widely applied in architectural aluminum profiles, new energy auto structural parts, 3C electronic housings, hydraulic hardware, aerospace lightweight components and medical titanium alloy parts.

1. Customizable Full-Range Thickness, Ultra-Uniform Coating
   • Complete thickness options from thin 5μm decorative coating up to 120μm heavy-duty wear-resistant ceramic film, adjustable as per drawing tolerance requirements;
   • Precise soaking time controlled by automatic traveling crane, stable current density from high-precision SCR power supply, constant temperature maintained by plate heat exchanger to restrain film dissolution. Thickness deviation controlled within ±1μm for full profiles & complex workpieces, eliminating edge thin film and uneven color issues;
   • Stable batch consistency reduces inspection & rework cost for mass production.
2. Three Complete Coating Systems for All Industries
   1. Conventional Decorative Anodizing Film: Cost-effective, abundant micropores for vivid dyeing, ideal for indoor colorful decorative products with transparent bright gold & multi-color finishes;
   2. Hard Anodizing Film: Low-temperature dense hard coating with scratch & abrasion resistance, standard for engineering machinery and hydraulic wear-resistant components;
   3. MAO Micro-Arc Ceramic Film: Ceramic alumina phase generated by high-voltage micro-arc discharge, far higher hardness than ordinary anodizing, acid & alkali resistant, insulating and high-temperature resistant for high-end military, medical and new energy parts.
3. Diverse Surface Finishes: Matte, Bright, Multi-Color All In One
   • Pre-treatment matched with caustic etching matte tank & wet sanding equipment for ultra-fine satin matte, coarse fog matte and mirror bright base surface;
   • Two coloring technologies optional: organic dye coloring (vivid bright gold & rich colors) & tin-nickel electrolytic coloring (weather-resistant champagne gold & bronze, no fading for decades outdoors);
   • Multi-stage counter-current rinsing + RO pure water system avoids water stains, color bleeding and uneven dyeing defects.
4. Superior Anti-Corrosion & Weather Resistance, Eco-Friendly Sealing for Long-Term Protection
   • Equipped with RO pure water equipment & medium-temperature nickel acetate sealing system to seal nanoscale micropores and isolate corrosive media;
   • Architectural-grade film over 15μm achieves salt spray resistance over 1000 hours; MAO ceramic film reaches 2000h salt spray resistance, no chalking, whitening or discoloration under long-term outdoor UV exposure;
   • Full production line equipped with three-acid mist treatment & aluminum ion recovery environmental equipment, all coating production complies with local emission standards for smooth environmental assessment.
5. Compatible with Full Series Aluminum Alloys, Uniform Coating for Complex Shapes

   Fits 6061, 6063, 7075, cast aluminum, die-cast aluminum, magnesium alloy and titanium alloy. Uniform intact oxide film forms on extruded profiles, machined irregular parts, deep holes and threaded workpieces without missing coating or breakdown defects.

6. Integrated Production Line Matching, Stable & Reproducible Process

   Cooperated with MEIAL full set of automatic / vertical / manual / mini oxidation equipment including power supply, temperature control, circulation and filtration systems, no independent chemical debugging required for customers. We provide on-site coating process commissioning, operator training and intelligent production report management as one-stop after-sales service.
