Anodizing Services at Senotech Surface Coating
What is Anodizing?
Anodizing is a high-quality process used to coat metals, particularly aluminium, with a protective oxide film. This oxide layer is not only electrically insulated but also acts as a shield against white rust corrosion, ensuring the longevity and durability of the material. Anodizing is widely used in various industries, from railway components to engineering applications, offering exceptional protection and finish.
At Senotech Surface Coating, we specialize in anodizing for items as large as 18 feet in length, perfect for channels and railway items, while also providing high-thickness coatings for specialized engineering and industrial needs.
Our Anodizing Process: Precision and Quality
Our anodizing process follows a carefully structured sequence to ensure consistent quality and superior protection:
Non-Etching Soak Cleaning
Thorough cleaning to remove dirt and contaminants, preparing the surface for coating.
Water Wash
The component is washed with plain water to remove any residual cleaning agents.
Alkaline Etching
The aluminium surface is etched to prepare for the anodizing process, creating the optimal surface texture.
Water Wash
A rinse with plain water to remove any alkaline residues.
Desmutting
Removal of any smut or contaminants that might interfere with the anodizing process.
Water Wash
Another wash to ensure the surface is clean before moving forward.
Acidic Cleaning (Optional)
Optional cleaning using acidic solutions for additional surface preparation.
Water Wash
A final rinse with water to ensure no chemicals remain.
Anodizing with Sulphuric Acid
The aluminium is anodized in a sulphuric acid solution, with a controlled temperature between 18-20°C using a chiller. Electrolysis is carried out at 12-14 volts with lead sheets as cathodes and the aluminium parts as anodes.
Water Wash
Rinsing with water to remove any remaining acid or chemicals.
Electrocolouring
The anodized surface is coloured by using special salts and additives, offering a range of custom colour shades based on client preference.
Water Wash
A final wash with water to ensure the surface is clean and free from any colouring agents.
Sealing of Anodized Surface
The anodized aluminium is sealed to enhance corrosion resistance. We use either hot sealing or cold sealing chemicals, depending on the requirements of the project.
Air Drying
The final anodized product is carefully dried in the air to complete the process.
