2000T/M Aluminum Anodizing Line For Metal Electroplating Surface Treatment

2000T/M Aluminum Anodizing line for Metal electroplating surface treatment

一. Pruduction: 

1.Increasingly, anodizing production lines are incorporating remote monitoring and control capabilities, allowing key personnel to access and manage the production processes from off-site locations. This enhances operational flexibility and responsiveness.

2.Anodizing production lines may utilize specialized simulation software to model and optimize various aspects of the anodizing process, such as current distribution, coating thickness, and process kinetics.

3.Advanced anodizing production lines employ sophisticated metrology and inspection tools, including optical profilometry, X-ray fluorescence, and automated visual inspection systems, to ensure precise measurement and verification of critical coating properties.

四. Treatment Process:

1. Degreasing
   (1) 6jig(rack)/ tank x 1 tank=6jig(rack)
   (2) treatment time: 2-5min
2.  Alkaline Etching 
   (1) 6jig(rack) / tank x 2 tank=12jig(rack)
   (2) treatment time: 3-15min
3.  Neutralization
   (1) 6jig(rack) / tank x 1 tank=6jig(rack)
   (2) treatment time: 1-5min           
4.  Anodizing
   (1) 3 jig(rack)/tank x 6tanks = 18jig(rack)
   (2) Current density: 130A/m²
   (3) Process time: 30min
   (4) Unprocess time: 10min
   (5) Total time 30+10=40min      

          (6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um

5.  Colour 1

                     1) Clour process: Mix Salts

                     2) Quantity:3 jig(rack)/tank x 1tanks = 3jig(rack)

                     3) Current density: 70A

                     4) Process time: 2-8min

      6. Sealing
           1) Sealing menthod:  Sealing at Medium or Normal Temperature
           2) Quantity: 6jig(rack)/tank x 1 tank
           3) Process time 10-15min

五.Process Tank

1. Degreasing 【Free sulfuric acid 180±30 g/l】 1 Tank
2. Alkaline Etching【Free alkali 40-60g/l,Al3+ 30-120g/】 2 Tanks
3. Neutralization 【Free sulfuric acid180±20g/l】 1 Tank
4. Anodising 【Free sulfuric acid 140-180g/l,Al3+≤20g/l】 6 Tanks
5. Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】 3 Tanks
6. Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 3 Tank

六. Design Parameter and Setting

       1. Anodizing treatment area:
              1) Each anodizing process tank need 40min ,where total jig(rack)/year:​

                   ( 3 rack x 6 tank x 60min/h) ÷40min x600 hour =16200jig(rack)

2) Design 50m²^/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 16200jig(rack)x 50m² /jig =810000m²

2. Anodizing treatment weight:
        Monthly output : 810000m²÷350m²/T*0.9=2082T≧2000T

3. Power consumption:
        1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank

           Power Rectifier : 15000A =6unit
        2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

   Colour Rectifier : 8000A =3 unit
