Aluminum Modular Anodizing Line Process With Manual Racking System

Aluminum Modular Anodizing Line Process With Manual Racking System

一.Description

An anodizing production line is a specialized industrial system used for the process of anodizing, which is an electrochemical treatment to enhance the surface properties of metal objects, typically aluminum.

二.Detail

1.The production line usually starts with a pre-treatment section, where the metal objects undergo cleaning and preparation before the anodizing process.

2.The anodizing tanks are the core components of the production line.

3.After the anodizing process, a coloring step may be included in the production line.

4.Throughout the production line, rinse tanks are used to remove residual chemicals and contaminants from the metal objects.

四.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】                                          4 Tanks
5.  Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】          2 Tanks
6. Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 1 Tank 

五.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) 2 jig(rack)/tank x 4tanks = 8jig(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:2 jig(rack)/tank x 1tanks = 2jig(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

六. Design Parameter and Setting

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

                   ( 2 rack x 4 tank x 60min/h) ÷40min x600 hour =7200jig(rack)

2) Design 50m²^/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 7200jig(rack)x 50m² /jig =360000m²

2. Anodizing treatment weight:
        Monthly output : 360000m²÷400m²/T*0.9=810T≧800T

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

           Power Rectifier : 15000A =4unit
        2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

   Colour Rectifier : 8000A =2 unit
