High-Performance Electroplating Oxidation Production Line for Aluminum Profiles and 3C Accessories
Equipment Description:
I. Definition and core features
1. Definition
The fully automatic vertical oxidation production line adopts a vertical processing method and is specially designed for aluminum profiles, 3C accessories and other products. It integrates pretreatment, anodizing, electrophoretic coloring, closed drying and other modules to achieve continuous automated production.
2. Core features
Vertical layout : Vertically hoist the workpiece to reduce the space occupied by horizontal transmission, and the floor area is only 50% of the traditional horizontal line.
Full process automation : Through PLC + touch screen control, unmanned operation of driving movement, process parameter adjustment, and tank liquid monitoring is realized.
High-precision process control : Supports online detection and feedback adjustment of parameters such as oxide film thickness and dyeing uniformity (error ≤ 2mm).
II. Technical parameters and performance
Processing capacity Monthly production capacity of a single line: 2500-10000 tons (expandable design).
Oxide film performance Thickness uniformity error ≤ 5%, hardness ≥ 300HV;
Dyeing uniformity meets ASTM B137 standards.
Energy consumption and environmental protection Energy consumption is reduced by 20-30% (compared with horizontal lines), and the wastewater reuse rate is ≥80%; Waste gas treatment system (alkaline solution spraying + activated carbon adsorption), VOC emission ≤50mg/m³.
III. Application scenarios
Large-scale industrial profiles: products with high corrosion resistance requirements such as building curtain walls and automotive structural parts.
Precision electronic components: fields with high requirements for surface uniformity such as mobile phone middle frames and engine parts.
High value-added decorative parts: color electrophoretic aluminum profiles, metal texture surface treatment.

Main structures and components:
I. Pretreatment system
1. Cleaning tank group
Degreasing tank : Alkaline solution (NaOH concentration 50-80g/L) removes oil stains on the surface of aluminum. The tank body is made of corrosion-resistant PP material, and the automatic spray device is used to improve the cleaning efficiency. Alkali etching tank : NaOH solution (50-100g/L) corrodes the surface of the aluminum substrate to eliminate microscopic defects. The tank is equipped with a circulating filtration system to keep the solution active. Neutralization tank : Nitric acid/sulfuric acid mixture neutralizes residual alkali solution and activates the surface. The tank body and degreasing tank share corrosion-resistant materials. Multi-stage water washing tank : Municipal water + pure water automatic cleaning, equipped with a drip drying device to reduce the amount of liquid carried out and save water. 2. Automated auxiliary equipment
Ultrasonic cleaning module (optional): Improve surface cleanliness to Sa2.5 standard and reduce manual intervention.
II. Anodizing unit
1. Electrolytic cell
Cell design: Acid-resistant PP/PVC material, single cell volume can reach 3-4 times of horizontal line, suitable for continuous production of large-size aluminum profiles.
