Aluminum Profile Anodizing Production Line

Product Specifications

Technical details and manufacturing context for Aluminum Profile Anodizing Production Line

Definition

This production line is an integrated industrial system for the electrochemical anodization of aluminum profiles and fabricated components. It automates sequential surface treatment processes including cleaning, etching, anodizing, coloring, and sealing. The line comprises coordinated modules such as material handling systems, chemical treatment tanks, power supply units, and drying stations. It enables controlled oxide layer formation for enhanced corrosion resistance, durability, and aesthetic finishing of aluminum products.

The line handles profiles with lengths from 6000 to 12000 mm, operates at production speeds of 0.5 to 2.0 m/min, and has a footprint of 500 to 1500 m² depending on configuration. Anodizing voltage ranges from 15 to 25 V DC, with current density typically 1.0 to 2.0 A/dm² for sulfuric acid anodizing. Operating temperature is maintained between 15 and 25 °C. Coating thickness can be controlled from 5 to 25 μm, with sealing quality verified by ISO 3210 (mass loss ≤30 mg/dm²). Tank capacities range from 20 to 60 L, and rinse water consumption is 5 to 15 m³/h. Total installed power is 100 to 500 kW, and air supply pressure for pneumatic controls and agitation is 0.5 to 0.8 MPa. Noise level at operator position is ≤75 dB(A) per ISO 11201.

Materials of construction include stainless steel tanks, PVC/PP piping, aluminum cathodes, and epoxy-coated steel frames. The line is designed for aluminum product manufacturing facilities. All listed parameters are reference ranges; model-specific values and applicable standards must be confirmed with the legal manufacturer or supplier.

Working Principle

The working principle is based on an electrochemical process where aluminum profiles act as anodes in an electrolyte bath, typically sulfuric acid. A controlled DC current is applied, causing oxygen ions to react with aluminum at the surface, forming a protective aluminum oxide layer. The thickness and properties of this layer are controlled by current density, voltage, temperature, and processing time. The line integrates pre-treatment (cleaning, etching), anodizing, coloring (if required), and sealing to produce a uniform, corrosion-resistant finish.
