Colour Anodising and Colour Matching Service: (Sub Sulphuric)
Anodising is an electrochemical process that increases the thickness of the natural oxide layer on the surface of Aluminium. This process not only enhances the aluminium’s resistance to corrosion but also allows for vibrant colour finishes, which can be used for both decorative and functional purposes. Our colour anodising process ensures consistent, long-lasting results that do not peel, fade, or chip over time.
Steps in the Colour Anodising Process:
-
Surface Preparation: Prior to anodising, the Aluminium surface is cleaned and pre-treated to remove any contaminants, such as oils, grease, and oxides. This ensures an optimal surface for the anodising process.
• Anodising: The aluminium is immersed in an electrolytic bath and exposed to an electric current. This process creates a thicker oxide layer, which is the key to the durability and appearance of anodized aluminium. -
Colouring: After anodising, the part undergoes a colouring process where the oxide layer is dyed with special anodising dyes. This process is typically done in an aqueous dye solution.
-
Dyeing: The dye bonds with the porous oxide layer, allowing for a wide range of colours to be applied, including vibrant tones and subtle metallic hues.
-
Sealing: After the part is dyed, the oxide layer is sealed to lock in the colour and enhance corrosion resistance. This is typically done through boiling water or a chemical sealing process.
Types of Colours We Offer:
-
Bright Colours: Vibrant colours such as reds, blues, and greens.
-
Subtle Shades: Natural metallic shades such as bronze, gold, and champagne.
-
Custom Colours: Customised colour options to suit specific requirements.
-
Matt and Gloss Finishes: We offer both matt and glossy finishes, depending on the client’s preferences and the part’s intended use.
Colour Matching Services:
At Majestic Aluminium Finishing Ltd, we understand that consistency in colour is critical, especially in applications like architecture, automotive, and electronics. Our colour matching services are designed to ensure that the anodized aluminium matches a specific shade or tone exactly as required.
Colour Matching Process:
-
Client’s Colour Reference: Clients can provide a physical colour sample or a reference to match, such as a Pantone code, RAL colour, or a custom sample.
-
Colour Formulation: Our skilled technicians use advanced equipment to analyse the reference and formulate the exact dye mixture needed to match the requested colour. We use both digital and visual inspection methods to ensure accuracy.
-
Test Runs and Samples: Before moving into full production, we conduct test runs to ensure that the anodized finish matches the desired colour. This includes producing sample parts that are dyed and sealed to confirm the result.
-
Approval and Production: Once the test samples are approved, we proceed with full-scale production. Each batch is monitored to maintain consistency in colour and finish.
Colour Matching Technology:
-
Spectrophotometers: We use spectrophotometric devices to accurately measure the colour and ensure the dye mixture matches the reference sample. This ensures precise, repeatable colour matching, especially for complex or custom colours.
-
Manual Visual Checks: Along with technology, we rely on experienced technicians to visually assess the colour in different lighting conditions to guarantee that the anodized finish looks perfect both under natural light and artificial lighting.
