3000T/M Vertical Anodizing Line with Type II Sulfuric Acid Anodizing and Electrophoretic Coating for Outdoor Tent Frames

This production line is specifically designed for surface treatment of aluminum profiles and tubes used in outdoor tent frames. It features a vertical layout with Type II sulfuric acid anodizing followed by electrophoretic coating. The project target capacity is 3,000 tons per month, with final capacity depending on profile section, racking density, process cycle, shift pattern, and yield.

Outdoor tent frames are exposed to rain, UV light, and temperature changes. Type II sulfuric acid anodizing forms a porous oxide layer that provides a base for coloring and corrosion resistance. The electrophoretic coating applied over the anodized surface enhances weather resistance and provides mechanical protection. The vertical line configuration is particularly suitable for long aluminum tubes and profiles, making handling and transfer between tanks more manageable for extended workpieces.

Loading → Pre-treatment (degreasing, etching, desmutting) → Rinsing → Type II sulfuric acid anodizing → Rinsing → Coloring (optional) → Sealing / electrophoresis pre-treatment → Electrophoretic coating → Recovery / rinsing → Curing → Unloading.

This represents a typical process flow. Final tank quantity, process time, bath concentration, and temperature are confirmed during the project process design phase.

• Vertical layout: Suitable for long tent frame tubes and profiles, with easier handling between tanks
• Type II + electrophoresis: The anodized layer provides a base for coloring and corrosion resistance; the electrophoretic coating supports outdoor weather resistance and surface protection
• Automatic control: Process parameters can be set, stored, and recorded for batch management and repeatable production
• Paint recovery: The RO recovery system helps reduce electrophoresis paint consumption and stabilize rinsing tank conditions
• Exhaust treatment: Acid/alkali fume treatment supports workshop environment and project environmental requirements
• Configurable capacity: Power supplies, tanks, curing oven, and handling systems can be configured to the target capacity and product length

• What anodizing process is suitable for outdoor tent frames?
  Type II sulfuric acid anodizing with electrophoretic coating is commonly used. Final film thickness, color, and weather resistance requirements are set by the order and project specification.
• What is the purpose of Type II anodizing plus electrophoresis?
  Anodizing provides a base for corrosion resistance and coloring. The electrophoretic coating supports weather resistance, UV exposure performance, and surface protection. This combination is used for outdoor aluminum profiles.
• What profile length can a vertical anodizing line handle?
  A vertical line suits long profiles. The maximum length is determined by tank depth and factory conditions, and should be designed according to the product drawing.
• How is 3,000 t/month capacity calculated?
  It is calculated from profile weight per meter, number of parts per rack, cycle time, working shifts, and yield. Final equipment quantity and tank dimensions are confirmed after project evaluation.
• What equipment is included in the line?
  Pre-treatment, anodizing, electrophoresis, power supplies, chiller, curing oven, loading/unloading, crane, pure water, recovery, fume treatment, and control system.
• How is color consistency managed?
  It is managed through process parameters, bath maintenance, batch records, and inspection. Final color tolerance should be agreed in the project technical specification.
