Product Description

600T/M Fully Automatic Anodizing Line for Kitchen & Bath Fittings

High-throughput anodizing system engineered for humid environments. Delivers electrolytic coloring in Brushed Silver, Gun Black, and Champagne with medium-temperature nickel salt sealing.

Overview

This fully automatic anodizing line is designed for manufacturers supplying kitchen and bathroom hardware into high-humidity environments. With a monthly capacity of 600 metric tons, it integrates pre-treatment, electrolytic coloring, and medium-temperature nickel salt sealing into a single automated workflow.

The system ensures consistent film thickness, uniform color distribution, and UV-fade resistance—critical for faucet handles, shower rails, towel racks, and cabinet pulls exposed to daily moisture and cleaning chemicals.

Technical Specifications

Parameter	Specification
Monthly Capacity	600 T/M
Operation Mode	Fully Automatic (Gantry Type)
Workpiece Type	Kitchen & bath fittings (faucets, handles, rails, brackets)
Base Material	Aluminum alloy 6061 / 6063 / die-cast ADC12
Anodizing Type	Sulfuric acid anodizing (Type II, decorative)
Film Thickness	8 – 15 μm (standard); up to 25 μm on request
Coloring Method	Electrolytic coloring (AC electrolysis)
Available Colors	Brushed Silver, Gun Black, Champagne
Sealing Method	Medium-temperature nickel salt sealing (60 – 70°C)
Sealing Quality	≥ 300 mg/dm² weight loss per ISO 3210
Corrosion Resistance	≥ 500 hours CASS test (humid environment rated)
UV Fade Resistance	≥ Grade 4 per ISO 105-A02 (electrolytic pigment locked in pores)
Water Rinse Stages	3-stage cascading rinse + 1 DI rinse
Wastewater Treatment	Integrated neutralization + heavy metal precipitation
Control System	PLC + HMI touch panel; recipe storage for 99 products
Energy Consumption	~180 – 220 kWh/ton (variable by load)

Process Flow

Loading — Jigs loaded onto overhead conveyor; barcode scan initiates recipe
Degreasing — Alkaline soak at 55°C to remove machining oils and fingerprints
Water Rinse — Overflow cascade rinse, conductivity monitored
Pickling / Desmuting — Acid dip to remove oxide scale and smut
Water Rinse — Second rinse to prevent cross-contamination
Anodizing — Sulfuric acid electrolysis at 18 – 22°C; DC rectifier 15 – 18 A/dm²
Water Rinse — Remove residual acid before coloring
Electrolytic Coloring — AC current deposits metallic salts into porous oxide film; color locked at molecular level for UV stability
Water Rinse — Stop coloring reaction precisely
Nickel Salt Sealing — Medium-temperature bath (60 – 70°C) hydrates and seals pores; enhances corrosion resistance for humid environments
Water Rinse — Remove sealing residue
DI Water Rinse — Final deionized rinse to prevent water spots
Hot Air Drying — 80°C circulated air; moisture eliminated before packing
Unloading & Inspection — Film thickness, color consistency, and seal quality checked per AQL standard

Core Advantages

Built for Humidity

Medium-temperature nickel salt sealing achieves ≥500 hours CASS corrosion resistance. Ideal for bathroom and kitchen environments with constant moisture exposure.

UV-Stable Electrolytic Colors

Unlike organic dyes, electrolytic coloring deposits metallic pigments inside the oxide pores. Brushed Silver, Gun Black, and Champagne retain their appearance after prolonged UV exposure.

Fully Automatic Consistency

Gantry transfer system eliminates human error in dwell time and temperature. Batch-to-batch color deviation controlled within ΔE ≤ 1.0.

Recipe-Driven Flexibility

PLC stores 99 product recipes. Switching from Gun Black to Champagne takes <15 minutes—no manual parameter re-entry.

Integrated Wastewater Compliance

Built-in neutralization and nickel recovery module ensures discharge meets local environmental regulations without external treatment plant investment.

Supporting Equipment

Equipment	Function
Overhead Gantry Transfer System	Automated jig movement between tanks; programmable dwell time ±2 sec accuracy
DC Rectifier (Anodizing)	12V / 8000A thyristor-controlled; ripple <5% for uniform film growth
AC Coloring Rectifier	18V / 3000A sinusoidal output; essential for even metallic pigment deposition
Medium-Temp Sealing Tank	60 – 70°C nickel acetate/fluoride bath; PID temperature control ±1°C
Cascading Rinse Tanks	3-stage counterflow; reduces water consumption by 40% vs. single-tank rinse
DI Water Generator	Reverse osmosis + mixed-bed ion exchange; conductivity <10 μS/cm
Hot Air Dryer	Circulating oven at 80°C; prevents water staining on decorative finishes
Wastewater Treatment Unit	Chemical precipitation + pH adjustment; handles Ni²⁺, F⁻, and Al³⁺

Frequently Asked Questions

Why is electrolytic coloring recommended over organic dyeing for kitchen and bath fittings?

Electrolytic coloring deposits metallic ions (Sn, Ni, Co) directly into the anodic pores. These pigments are locked within the aluminum oxide crystal structure, making them resistant to UV fading, heat, and household cleaners. Organic dyes sit on the surface and degrade faster in humid, high-UV environments.

What is the difference between medium-temperature nickel sealing and hot water sealing?

Hot water sealing (95 – 100°C) hydrates aluminum oxide into boehmite, closing pores. Medium-temperature nickel salt sealing (60 – 70°C) adds nickel ions that accelerate pore closure and improve corrosion resistance—critical for bathroom fittings exposed to chlorinated water and steam. It also reduces energy costs by ~35% compared to boiling water sealing.

Can this line handle small, irregular-shaped bathroom accessories like hinges and brackets?

Yes. The gantry system uses adjustable titanium jigs and custom racking fixtures. Parts as small as 50 mm can be secured without contact marks. We design fixtures during the DFM (Design for Manufacturing) phase based on your CAD files.

What is the lead time from deposit to commissioning?

Standard lead time is 90 – 120 days (design 15 days, fabrication 60 days, installation & commissioning 30 – 45 days). Shorter lead times available for standardized configurations.
