450 TPM Vertical Anodizing & Electrolytic Coloring Line | Champagne Color Series Specializedby GUANGDONG MEI-AL TECHNOLOGY CO., LTD.

This vertical anodizing production line is purpose-designed for aluminum profile manufacturers with a 450-ton monthly outputdemand, focusing on anodizing + electrolytic coloring processes (electrophoresis-free) and specialized in mass production of champagne color series finishes.

Eliminating redundant electrophoresis sections, the line is optimized for core surface treatment workflows: pre-treatment → sulfuric acid anodizing → electrolytic coloring → multi-stage rinsing → sealing. It is ideal for architectural aluminum profiles, door & window frames, decorative panels and furniture aluminum materials, solving common industry diffficulties such as large vertical color difference, unstable champagne tone consistency, uneven film thickness and insufficient production capacity.

As a professional aluminum surface treatment equipment manufacturer with over 10 years of experience, GUANGDONG MEI-AL delivers turnkey vertical anodizing lines tailored to champagne color mass production, helping clients achieve high yield, stable quality and efficient large-volume production.

The line is streamlined for anodizing and coloring production, removing unnecessary electrophoresis sections to improve production efficiency and reduce investment cost:

1. Pre-treatment: Degreasing → Alkaline etching → Neutralization → Multi-stage countercurrent rinsing
2. Core process: Sulfuric acid anodizing → Electrolytic coloring (champagne series dedicated)
3. Post-treatment: Multi-stage pure water rinsing → Nickel-free sealing → Drying

As the core highlight of this line, the electrolytic coloring system is deeply optimized for champagne tone production to ensure ultra-high batch consistency:

• Full champagne color gamut: Supports light champagne, medium champagne, dark champagne, bronze and other classic champagne series tones via tin salt / tin-nickel mixed salt electrolytic coloring process.
• Vertical uniform coloring: Vertical hanging structure ensures consistent coloring depth from top to bottom of long profiles, eliminating upper-lower color difference defects common in horizontal lines.
• High-precision bath control: Equipped with dedicated concentration detection and automatic dosing system, stably controls metal salt concentration, pH value and temperature of coloring bath, minimizing batch-to-batch color deviation.
• Color consistency guarantee: Matched with constant current / constant voltage coloring power supply and precise timing control, each workpiece receives identical coloring conditions, meeting strict color difference standards for architectural curtain wall profiles.
