Process Workflow
Ultrasonic Degreasing & Hot Alkaline Wash: Removes drawing oils, lubricants, and residual metal shavings from formed wire meshes.
Multi-Stage Cascade Rinsing: Prevents chemical carryover across processing tanks and optimizes industrial water consumption.
Acid Etching & Desmutting: Clears surface oxide layers and alloy intermetallics to ensure complete visual uniformity.
Automated Anodizing: Forms an insulated, highly porous aluminum oxide layer under controlled current density and bath temperature.
Electrolytic / Chemical Coloring (Optional): Applies uniform custom color pigmentation for aesthetic appliance lines.
High-Temperature Nickel / Hot Water Sealing: Seals micro-pores to ensure scratch protection and anti-corrosion performance.
Automated Hot Air Drying & Unloading: Dries parts completely to prevent water spotting and prepare parts for final inspection.
Core Engineering Advantages
High Throwing Power for Complex Geometries: Specialized tank cathode configurations ensure complete current penetration across dense wire grill joints and bent bracket surfaces.
Batch Consistency & Low Rejection Rates: Automated hoist indexing and digital recipe management eliminate operator-induced variations in immersion time and current density.
Heavy-Duty Energy Efficiency: Equipped with high-frequency IGBT rectifiers and thermal insulation tanks, lowering continuous electrical consumption by up to 20%.
Corrosion & Chemical Safety: Structural steel frames are treated with multi-layer anti-corrosion coatings, complemented by integrated exhaust and push-pull ventilation hoods.
Auxiliary & Support Equipment
Bath Temperature Control Units: Heavy-duty titanium heat exchangers paired with precision industrial chillers.
Air Agitation & Filtration Systems: Continuous chemical bath filtration to eliminate suspended particles and minimize surface pitting.
Exhaust & Acid Mist Scrubbers: Wet acid-mist purification systems compliant with industrial emission standards.
Zero Liquid Discharge (ZLD) / Wastewater Treatment Integration: Inline chemical dosing and heavy metal settling systems for eco-friendly discharge.
Frequently Asked Questions
How does the system ensure uniform coating on complex wire mesh fan grills?
The line utilizes targeted auxiliary cathodes and customized jigging fixtures combined with automated air agitation to prevent air pockets and ensure balanced current density across all wire joints.
Can this production line switch between decorative and industrial finishes?
Yes. The PLC system stores multiple pre-configured operational recipes, allowing fast changeovers between thin decorative anodizing (8–12 μm) and thicker functional wear-resistant coatings (15–25 μm).
What is the typical floor space and ceiling height required for installation?
Equipment footprints vary based on monthly capacity targets (e.g., 80 to 150+ tons/month). Our engineering team supplies customized layout drawings based on your plant dimensions and crane clearance.
