This horizontal automatic anodizing production line is engineered for high-volume surface treatment of precision 3C aluminum components, including smartphone frames, laptop enclosures, tablet structures, and wearable device parts. Designed for a monthly throughput of 950 tons, the line integrates automated chemical pre-treatment, precision anodizing, multi-stage rinsing, and sealing processes. Equipped with an automated gantry crane transfer system and centralized PLC control, the facility maintains consistent coating parameters and structural uniformity across high-density production batches.

High-frequency switching rectifiers provide stable DC output and precise current density control, ensuring predictable oxide growth rates and uniform film thickness across complex 3C component geometries.
A central PLC system manages hoist movement schedules, immersion times, temperature profiles, and rectifier parameters with real-time data logging to reduce human error and support traceability.
Automated chemical dosing systems and temperature-regulated dye tanks maintain stable bath compositions, reducing shade variations across production runs.
Industrial chillers combined with titanium heat exchangers regulate electrolyte temperatures within set thresholds, while continuous multi-stage micron filtration maintains bath clarity and finish quality.
The tank layout supports interchangeable pre-treatment options, allowing transitions between high-gloss chemical polishing, satin etching, and matte anodizing depending on product specifications.
The line supports Type II standard sulfuric acid anodizing for decorative finishes and Type III hard anodizing for components requiring enhanced abrasion resistance.
Current density is regulated via high-frequency switching rectifiers connected to the central control system, maintaining precise voltage and current parameters throughout the anodizing cycle.
The system utilizes screw chillers paired with titanium plate heat exchangers and continuous bath circulation pumps to maintain solution temperature within ±1°C of the setpoint.
The line utilizes automated chemical replenishment units, precise temperature control, and continuous bath agitation in the dyeing section to maintain constant dye concentrations.
An integrated aluminum ion stabilizer continuously removes excess Al³⁺ ions from the bath via resin separation while recycling sulfuric acid back into the tank.
We provide full-scope engineering design, equipment sizing, plant layout planning, and technical support tailored to your production volume and product specifications.
