2,200 Tons/Month PLC-Controlled Aluminum Anodizing Production Line for Type II & III Surface Treatment

This turnkey anodizing production line is engineered for manufacturers of aluminum fire fighting equipment components in Saudi Arabia. The complete system covers the entire process chain—from pre-treatment through anodizing to sealing—within a PLC-controlled automated framework.

The system supports both conventional sulfuric acid anodizing (Type II) and hard anodizing (Type III) for aluminum components used in fire fighting equipment, including valve bodies, connectors, adapters, and structural brackets. These components require surface treatment to enhance corrosion resistance and wear performance in outdoor and high-moisture environments.

With a capacity of 2,200 tons per month, the line is configured for large-scale production of small to medium-sized aluminum fire fighting parts. Process parameters are fully adjustable based on alloy composition, component geometry, and target film properties.

Each stage is controlled by the central PLC system, with automated gantry crane transfer between tanks. Rinse stages incorporate cascading counter-flow to reduce water consumption. The anodizing stage uses a high-frequency switching rectifier with stable DC output, and electrolyte temperature is maintained within set thresholds by an industrial chiller system.

A typical line layout includes the following major equipment:

• Automated Gantry Crane System: Multi-unit hoist system for rack transfer between tanks
• Process Tanks: Degreasing, alkaline etching, neutralization, anodizing, rinsing (multi-stage), coloring (optional), sealing
• Rectifier: High-frequency switching rectifier with stable DC output
• Chiller System: Industrial chiller with titanium heat exchanger for electrolyte temperature control
• Exhaust & Scrubber System: PP or FRP fume hoods with acid mist scrubber
• Chemical Dosing Station: Automated dosing pumps with pH/conductivity controllers
• PLC Control Cabinet: Central control with touchscreen HMI, recipe management, and data logging
• Drying System: Hot air dryer or centrifugal dryer
• Filtration System: Continuous multi-stage micron filtration for electrolyte clarity

The line footprint and tank dimensions are customized based on maximum workpiece size and required throughput.

Every production scenario differs in workpiece geometry, alloy mix, and throughput target. We provide customized line layouts and process solutions based on your specific requirements—including tank sizing, crane configuration, rectifier capacity, and treatment cycle design.
