Selecting an electro-coloring salt should not be based only on price. The chemical should be compatible with your anodizing process and the required final finish.
Before selecting a product, consider:
1. Required Colour:
Specify the desired anodized colour or shade.
2. Aluminium Alloy:
Different aluminium alloys can behave differently during anodizing and colouring.
3. Existing Process:
Provide details about your current anodizing and electro-colouring process.
4. Equipment:
The electro-colouring equipment and electrical parameters should be considered.
5. Production Requirement:
Large anodizing plants may require regular bulk supply and process consistency.
6. Sealing System:
The final sealing process should be compatible with the complete anodizing system.
Quality & Process Consistency
For an anodizing plant, chemical consistency is an important part of maintaining production quality. Variations in chemical concentration, contamination or operating parameters can affect colour development and surface appearance.
A controlled process combined with suitable raw materials and regular bath monitoring can help manufacturers maintain consistent production.
We therefore recommend that customers follow their established process specifications and technical operating procedures when using electro-colouring chemicals.
