Product Description

950 Tons/Month Automatic Horizontal Anodizing Production Line for 3C Aluminum Components

Overview

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.

Anodizing Process Flow

Loading → Chemical Degreasing → Rinse → Chemical Polishing / Alkaline Etching → Rinse → Acid Neutralization (Desmutting) → Rinse → Sulfuric Acid Anodizing / Hard Anodizing → Multi-stage DI Water Rinse → Organic Dyeing / Electrolytic Coloring (Optional) → DI Water Rinse → Nickel-Free / Medium Temperature Sealing → Hot Water Rinse → Drying → Unloading

Key Features

Controlled Film Thickness

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.

Automated Process Control

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.

Batch Color Uniformity

Automated chemical dosing systems and temperature-regulated dye tanks maintain stable bath compositions, reducing shade variations across production runs.

Temperature & Filtration Control

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.

Flexible Surface Finishing

The tank layout supports interchangeable pre-treatment options, allowing transitions between high-gloss chemical polishing, satin etching, and matte anodizing depending on product specifications.

Production Line Configuration

Automated Crane & Hoist System: Overhead multi-gantry cranes equipped with position sensors, variable frequency drives, and collision-avoidance logic for smooth rack transfer between process tanks.
Rectifier & Power Supply Units: High-frequency IGBT switching power supplies and SCR rectifiers featuring ripple control, automatic voltage/current regulation, and PLC integration.
Exhaust & Acid Mist Scrubber System: Lateral slot hoods, UPVC extraction ductwork, and countercurrent packed scrubber towers for neutralization of acid and alkaline vapors.
Chiller & Thermal Regulation System: Industrial screw-compressor chilling units, plate heat exchangers, and acid-resistant circulation pumps for continuous electrolyte temperature control.
Bath Filtration & Agitation Modules: Specialized acid-resistant magnetic/centrifugal pumps, UPVC piping networks, and cartridge filter units for bath homogenization and particulate removal.
Reverse Osmosis (RO) Water System: Multi-stage RO purification unit producing deionized water required for high-purity rinsing and sealing steps.
Aluminum Ion Recovery Unit: Online ion exchange system to control excessive Al³⁺ build-up in the anodizing bath, extending bath life and stabilizing bath conductivity.
Waste Water Treatment Facility: Neutralization tanks, double reactors, filter presses, and sludge handling equipment configured to meet local discharge standards.

Frequently Asked Questions

What anodizing types are supported on this production line for 3C parts?

The line supports Type II standard sulfuric acid anodizing for decorative finishes and Type III hard anodizing for components requiring enhanced abrasion resistance.

How does the line control film thickness uniformity on small electronic parts?

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.

How is bath temperature maintained during continuous anodizing?

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.

What measures prevent color variation in dyed 3C components?

The line utilizes automated chemical replenishment units, precise temperature control, and continuous bath agitation in the dyeing section to maintain constant dye concentrations.

How does the system manage aluminum ion concentration in the anodizing bath?

An integrated aluminum ion stabilizer continuously removes excess Al³⁺ ions from the bath via resin separation while recycling sulfuric acid back into the tank.
