900T/Month Anodizing Production Line for Aluminium 6061-6063 Alloy Product

900T/Month Anodizing Production Line for Aluminium 6061-6063 Alloy

一. Product Description 

1.The anodizing production line is a system specifically designed for anodizing aluminum products.

2.Immerse the processed aluminum products into an anodizing tank, apply electricity for anodizing, and form a uniform aluminum oxide film.

3.After anodizing, aluminum products need to be rinsed with water in multiple rinsing tanks to remove residual electrolyte and reaction products.

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) 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 : 0.3*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

五. 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÷350m²/T*0.9=925T≧900T

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 =2unit
