200-1500 Tons/Month Semi-Automatic Vertical Processing Anodizing Production Line for Aluminum Window Frames with Type II Sulfuric Acid Anodizing

This semi-automatic aluminum anodizing line is specifically designed for architectural aluminum profiles, primarily applied to standard and customized aluminum window frames, door frames, and building facade profiles. Utilizing the mature Type II sulfuric acid anodizing process compliant with architectural aluminum industry standards, the line supports conventional dye coloring and optional electrophoretic composite finishing to meet outdoor weather resistance and decorative requirements.

The production employs a professional vertical processing mode, equipped with travelling hoist crane and heavy-duty steel structure conveyor system. It combines mechanical cyclic conveying with manual auxiliary operation, specially optimized for vertical hanging processing of architectural aluminum profiles. The monthly output ranges from 200 to 1500 tons, covering small-batch customized orders and large-scale engineering batch production while maintaining stable and consistent surface processing quality for architectural aluminum products.

• Stable & Controlled Film Thickness: Matched with constant-current rectifier and timed oxidation control system, the line maintains uniform oxide film thickness on long and irregular window frame profiles, conforming to conventional architectural aluminum profile tolerance standards.
• Professional Vertical Processing Design: The whole line adopts exclusive vertical hanging processing mode, professionally optimized for long architectural profiles such as window frames. It avoids liquid accumulation and surface streaks easily caused by horizontal placement, ensuring uniform film formation and consistent appearance on the whole profile.
• Stable Batch Color Consistency: Equipped with closed-loop tank filtration and constant-temperature coloring system. It reduces color deviation among batches of window frame products, keeping uniform decorative appearance for engineering matching projects.
• Reliable Temperature & Filtration Control: Independent chilled water buffer tank and circulating cooling device lower temperature fluctuation during high-volume continuous production. Multi-cycle filtration reduces suspended impurities in tank liquid, stabilizing surface finish quality.
• Flexible Surface Finishing Solutions: Compatible with multiple architectural color schemes and surface textures. Process recipes can be stored and switched quickly to adapt to different window frame styles and project requirements.
• Optional Electrophoretic Upgrade: Reserved modular installation space and interfaces for electrophoretic coating system. It can switch freely between single anodizing and composite processes, suitable for high weather resistance outdoor building profiles.
• Anti-Cross Contamination Structure: Drip leakage drainage zone reserved between tanks collects residual electrolyte from hangers and profiles, lowering rinse water pollution and stabilizing long-term batch production quality.

• Conveying & Operation System: Heavy-duty travelling hoist crane, vertical special steel structure conveyor frame, semi-automatic vertical lifting and transmission mechanism, stable and reliable for long window frame profile hanging processing
• Pretreatment System: Degreasing tank, alkaline etching tank, neutralization tank, equipped with circulating filtration and liquid level monitoring accessories
• Core Anodizing System: Sulfuric acid anodizing tank, high-precision DC stabilized rectifier, tank liquid stirring and circulating filtration equipment
• Constant Temperature System: Industrial chiller, large-capacity chilled water buffer tank, plate heat exchanger, ensuring stable oxidation and coloring temperature
• Coloring & Sealing System: Decorative coloring tank, sealing tank with constant temperature control unit
• Pure Water Rinsing System: Multi-stage counter-flow pure water rinse tanks, reducing water consumption and improving rinsing cleanliness
• Drying System: Constant-temperature hot air drying oven with uniform air circulation for moisture-free drying of profiles
• Intelligent Control System: PLC control cabinet, HMI touch screen, temperature and timing sensing modules for standardized process management
• Environmental Protection & Auxiliary Facilities: Acid mist exhaust purification device, automatic chemical dosing system, workshop diversion trench and under-tank maintenance gallery
• Optional Upgrade Equipment: Reserved interface for electrophoretic rectifier, ultrafiltration recycling system and curing oven for composite finishing process
