Aluminum Anodizing Plant (10 to 25 Micron Finish)
State-of-the-art automated sulfuric acid electrolytic anodizing and electro-coloring plant. Transforming raw extruded aluminum sections into exceptionally hard, corrosion-resistant, and non-fading architectural surfaces.
Architectural Anodizing Color Finishes
Electrolytically bonded metallic salts locked deep inside the anodic oxide pores for permanent fade-free performance.
Natural Matt Silver (CA / Clear)
Classic satin silver finish highlighting pure aluminum metallic sheen with zero color fade.
6-Stage Chemical & Electrolytic Anodizing Lifecycle
Chemical Degreasing & Cleaning
Sections are immersed in alkaline degreaser tanks to eliminate die lubricants, grease, and atmospheric contaminants.
Caustic Etching / Matt Finish
Controlled caustic soda etching dissolves micro-surface imperfections to yield a smooth, uniform satin texture.
Acid Desmut & Deoxidizing
Nitric acid bath strips insoluble alloying elements (silicon, copper, iron) to reveal pure aluminum substrate.
Sulfuric Acid Anodizing Tank
Direct electrical current in chilled sulfuric acid (18-20°C) transforms the metal surface into a hard, crystalline Al2O3 layer.
Electro-Coloring (Tin / Nickel Salts)
Metallic salts are deposited deep inside the porous oxide column via AC electrolysis for permanent, non-fading shades.
Nickel Acetate Hot Sealing (96°C)
High temperature de-ionized water seal hydrates the pores into boehmite, locking colors and guaranteeing lifetime corrosion resistance.
