A Comprehensive Solution for High-Quality Aluminum Surface Finishing

➤ Modern Anodizing Line for High-Quality Products

Ngô Hoàng Co., Ltd.'s automatic aluminum anodizing line is designed with a production capacity of 5,000 tons per year, meeting the surface treatment requirements for a wide range of aluminum alloys, including 6063, 6061, 6082, 7075, and 2024. After anodizing, aluminum products achieve excellent corrosion resistance, enhanced surface hardness, superior color durability, and an improved aesthetic appearance.

➤ Integrated Surface Treatment Process

The production line incorporates a complete sequence of processing stages, including:

• Degreasing
• Alkaline etching
• Bright dipping (chemical polishing)
• Desmutting
• Anodizing
• Dyeing
• Sealing
• Water rinsing
• Drying

The bright dipping tank provides a highly polished aluminum surface, significantly enhancing the visual quality and appearance of the finished products.

➤ Flexible Configuration with High Productivity

The system is equipped with:

• Four (04) conventional anodizing tanks and one (01) hard anodizing (cold anodizing) tank.
• Two (02) dyeing tanks and two (02) sealing tanks, allowing simultaneous processing of various products with different colors and anodic coating thicknesses, thereby improving both production flexibility and throughput.
• Two (02) independently operated automatic overhead cranes, optimizing product transfer between process tanks, reducing cycle time, and increasing production efficiency.

➤ Dual Operating Modes

The production line supports both Automatic (Auto) and Manual operating modes.

Auto Mode

• The PLC automatically controls product transfer, processing time, and process sequence, ensuring stable and consistent product quality.

Manual Mode

• Individual equipment can be operated independently, making commissioning, maintenance, troubleshooting, and special processing requirements more convenient.

➤ Intelligent Control and Monitoring

The entire production line is controlled by a PLC system integrated with an HMI (Human-Machine Interface).

Operators can:

• Monitor equipment operating status
• Monitor anodizing current
• Monitor rectifier voltage
• Control processing time
• Monitor process tank temperatures
• Control pumps and valves
• Monitor alarms and fault conditions
• Store production data

This intelligent control system ensures precise process management, improving operational efficiency while optimizing production performance.

➤ Complete Auxiliary Systems

To ensure stable and continuous operation, the production line is integrated with the following auxiliary systems:

• Exhaust gas extraction and treatment system for collecting and treating acid and alkaline fumes, ensuring a safe working environment.
• Steam boiler system supplying heat to process tanks requiring heating, such as degreasing, dyeing, and sealing tanks.
• RO (Reverse Osmosis) water treatment system, providing high-quality water for rinsing and chemical solution preparation.
• Cooling Tower combined with a Chiller system to maintain stable temperatures in the anodizing tanks, especially the hard anodizing tank, ensuring consistent oxide coating quality while extending equipment service life.
