150 T/month Oxidation Production Line and Max Profile Length 6500mm

一. Product Description: 

1.An anodizing production line should have proper ventilation to control fumes and ensure a safe working environment.

2.A mini anodizing production line may have inspection stations or quality control measures to verify the quality of the anodized parts.

3.Anodizing processes involve working with hazardous chemicals and electrical currents.

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 1tanks = 2jig(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

五. Design Parameter and Setting

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

                   ( 2 rack x 1 tank x 60min/h) ÷40min x600 hour =1800jig(rack)

2) Design 42.9m²^/jig(rack) . Where every tank is 85.8m²
3) Area treatment/year : 1800jig(rack)x 42.9m² /jig =77220m²

2. Anodizing treatment weight:
        Monthly output : 77220m²÷400m²/T*0.9=174T≧150T

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

           Power Rectifier : 15000A =1unit
        2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

   Colour Rectifier : 8000A =1 unit
