Semi-Automatic Vertical Anodizing Production Line with 6500mm Profile Cut Length

This semi-automatic anodizing line equipped with travelling hoist crane and steel structure conveyor is professionally designed for surface finishing of CNC-machined aluminum bow grips and supporting archery hardware components. Adopting mature sulfuric acid decorative anodizing technology, the line supports organic dyeing and nickel-salt electrolytic coloring processes, and allows optional upgrade for electrophoretic coating composite process to meet diverse appearance and protective performance requirements of archery accessories.

The production adopts matched travelling crane and steel structural conveyor for workpiece transmission, with semi-automatic operation mode combining mechanical conveying and manual auxiliary positioning. With adjustable production configurations and continuous shift operation, the monthly production capacity stably ranges from 200 to 1500 tons, adaptable to small-batch trial production and large-scale mass production of aluminum bow grips, maintaining stable and consistent surface processing quality.

• Controlled Film Thickness: Equipped with constant-current rectifier and precise timing control system, the line matches stable oxidation parameters according to bow grip specifications, keeping uniform oxide film thickness for batches of workpieces and meeting consistent dimensional tolerance standards of archery parts.
• Automated Process Control: Matched travelling hoist crane and steel structure conveyor undertake stable workpiece transferring and fixed-position feeding. Cooperated with independent electrical control system, it standardizes process time, soaking duration and dripping procedures, reduces manual operation errors and ensures reproducible processing parameters for mass production.
• Batch Color Consistency: Adopts closed-loop tank body filtration and constant-temperature coloring system. The matched large-capacity chilled water buffer tank stabilizes coloring bath temperature, effectively controlling color deviation among different batches of aluminum bow grips.
• Temperature & Filtration Control: Independent circulating cooling system with large-volume ice water buffer equipment suppresses temperature fluctuation during high-load continuous production. Multi-stage circulating filtration devices reduce suspended impurities in the tank liquid, improving surface finish yield.
• Flexible Surface Finishing: Supports free switching of multiple surface textures and color schemes. Different process recipes can be stored for different bow grip models, realizing flexible production of multiple specifications in one line.
• Anti-cross Contamination Structure: Reserved drip leakage drainage area between adjacent tanks, which collects residual tank liquid dripping from workpieces and hangers, lowers rinse water pollution degree and reduces water replacement frequency for high-volume production.
• Optional Electrophoretic Composite Process: The line supports modular upgrade of electrophoretic coating system without replacing original travelling hoist crane and steel structure conveyor. It can switch freely between single anodizing and anodizing-electrophoresis composite processes, matching ordinary mass production and high-standard customized production demands. The composite layer improves surface abrasion resistance, fingerprint resistance and weather resistance of aluminum bow grips.

• Conveying & Operating System: Travelling hoist crane, heavy-duty steel structure conveyor and supporting electrical control system, suitable for stable cyclic conveying of bow grip workpieces under high-load production, with flexible manual auxiliary adjustment function.
• Pretreatment Tank Units: Degreasing tank, alkaline etching tank, neutralization tank, all equipped with matched circulating filtration and liquid level monitoring components to ensure stable pretreatment effect.
• Anodizing Core Equipment: Sulfuric acid oxidation tank, high-precision stable current DC rectifier, tank liquid circulating stirring device and multi-stage filtration system, ensuring uniform oxide film formation.
• Constant Temperature & Coloring Equipment: Electrolytic coloring tank, independent large-capacity chilled water buffer tank, industrial chiller and plate heat exchange system, maintaining constant temperature of process liquid during continuous production.
• Water Treatment Equipment: Multi-stage counter-flow pure water rinse tanks, supporting circulating water filtration and reuse, effectively reducing water consumption for high-volume production.
• Post-Processing Equipment: Sealing tank, constant-temperature hot air drying oven with uniform air supply, ensuring full sealing effect and moisture-free drying of workpieces.
• Intelligent Control & Detection Equipment: PLC integrated control cabinet, HMI touch screen, temperature sensor, liquid level sensor and timing control module, realizing standardized and repeatable process operation.
• Circulating & Filtering Auxiliary Equipment: Multi-functional industrial filter, chemical liquid circulating pump, precise dosing pump, supporting long-term stable operation of each process tank liquid.
• Environmental Protection & Maintenance Facilities: Acid mist exhaust and purification device, automatic chemical feeding system, workshop diversion trench and under-tank maintenance gallery, meeting long-term high-load operation requirements.
• Optional Upgrade Equipment: Reserved installation space and matched power & pipeline interfaces for electrophoretic coating unit, including electrophoresis rectifier, ultrafiltration recycling system and curing supporting equipment, supporting later modular upgrade of composite process.
