Customization And Flexibility Automated Anodizing Line Aluminium Alloy Profile
Customization and Flexibility Automated Anodizing Line Aluminium Alloy Profile
Description
- Anodizing production lines can accommodate different variations of the anodizing process to achieve specific results
- Anodizing production lines often incorporate systems to control the thickness of the anodized layer on the metal objects
- Some anodizing production lines are capable of performing Type III hard anodizing, also known as sulfuric acid hard anodizing or hardcoat anodizing
Features
- Modern anodizing production lines often incorporate automation and advanced control systems to enhance efficiency and consistency
- The design of racks and fixturing used in the production line is crucial for optimal anodizing results
- Anodizing production lines can consume significant amounts of electricity, especially during the anodizing process

Treatment Process
1. Degreasing
6 jig(rack)/tank x 1 tank = 6 jig(rack)
Treatment time: 2-5min
2. Alkaline Etching
6 jig(rack)/tank x 2 tanks = 12 jig(rack)
Treatment time: 3-15min
3. Neutralization
6 jig(rack)/tank x 1 tank = 6 jig(rack)
Treatment time: 1-5min
4. Anodizing
3 jig(rack)/tank x 8 tanks = 24 jig(rack)
Current density: 130A/m²
Process time: 26min
Unprocess time: 7min
Total time: 26+7=33min
Average anodizing layer: 0.36*1.3*26*0.77 = 9.4µm
5. Colour 1
Colour process: Mix Salts
Quantity: 3 jig(rack)/tank x 1 tank = 3 jig(rack)
Current density: 70A
Process time: 2-8min
6. Sealing
Sealing method: Sealing at Medium or Normal Temperature
Quantity: 6 jig(rack)/tank x 1 tank
Process time: 10-15min
Design Parameter and Setting
Anodizing Treatment Area
Each anodizing process tank needs 33min, where total jig(rack)/year:
(3 rack x 8 tank x 60min/h) ÷ 33min x 600 hour = 26181 jig(rack)
Design 50m²/jig(rack). Where every tank is 100m²
Area treatment/year: 26181 jig(rack) x 50m²/jig = 1309050m²
Anodizing Treatment Weight
Monthly output: 1309050m² ÷ 350m²/T x 0.9 = 3366T ≧ 3000T
Power Consumption
Anodising Tank: 100m²/tank x 130A/m² ÷ 0.9 = 14444A/tank
Power Rectifier: 15000A = 3 units
Colouring tank: 100m²/tank x 70A/m² ÷ 0.9 = 7777A/tank
Colour Rectifier: 8000A = 3 units
