Product Description

3000T / M Semiautomatic Anodizing Production Line 8-12µm


一.  Description

An anodizing production line is a specialized manufacturing system designed for the process of anodizing metal objects, typically aluminum. The purpose of an anodizing production line is to enhance the surface properties of these objects by creating a durable and corrosion-resistant oxide layer on their surfaces.


1.Before anodizing, the metal parts need to go through a pre-treatment process.

2.The anodizing tanks are the central part of the production line. They contain an electrolyte solution, typically sulfuric acid, which acts as an electrolyte.

3.An anodizing production line is equipped with control systems to monitor and regulate various parameters during the process.


三.Design Condition

1 Alloy Aluminium 6061 to 6063 or others
2 Anodizing film thinkness 9~ 12µm micron
3 Average coverage area 350m²/T (ton)
4 Max aluminium profile length 6500mm
5 Extrusion ratio 2.5kg/m²
6 Working hour/m 300d/m x 20h/d = 600h/m

三. 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】   8 Tanks
    5 Colouring 【stannous sulfate 3-8g/l,Free sulfuric acid 15-25g/l,PH 0.8-1.2】    3Tanks
    6 Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】    3 Tanks

四.Treatment Process:

  1. Degreasing
    (1) 6jig(rack)/ tank x 1 tank
    (2) treatment time: 2-5min
  2.  Alkaline Etching 
    (1) 6jig(rack) / tank x 2 tank
    (2) treatment time: 3-15min
  3.  Neutralization
    (1) 6jig(rack) / tank x 1 tank
    (2) treatment time: 1-5min           
  4.  Anodizing
    (1) 3 jig(rack)/tank x 8tanks = 24jig(rack)
    (2) Current density: 130A/m²
    (3) Process time: 26min
    (4) Unprocess time: 7min
    (5) Total time 26+7=33min

          (6) Average anodizing layer : 0.36*1.3*26*0.77 =9.4um

  1.  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


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


五. Design Parameter and Setting

       1. Anodizing treatment area:
              1) Each anodizing process tank need 33min ,where total jig(rack)/year:

                   ( 3 rack x 8 tank x 60min/h) ÷33min x600 hour =26181jig(rack)

2) Design 50m²/jig(rack) . Where every tank is 100m²
3) Area treatment/year :
26181jig(rack)x 50m² /jig =1309050m²


2. Anodizing treatment weight:
        Monthly output : 1309050m²÷350m²/T*0.9=3366T≧3000T


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

           Power Rectifier : 15000A =3unit
        2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

   Colour Rectifier : 8000A =3 unit
