3000T/Month Anodizing Horizontal Line Process Consistent Quality

Product Specification

3000T/Month Anodizing Horizontal Line Process Consistent Quality

一. Description: 

1.Anodizing production lines often incorporate filtration and purification systems to maintain the quality of the electrolyte solution. These systems remove impurities, suspended particles, and contaminants from the electrolyte, ensuring consistent anodizing results and prolonging the lifespan of the solution.

   2.Temperature control is crucial in the anodizing process to achieve desired coating properties and process stability. Anodizing production lines may include heating or cooling systems to maintain the electrolyte solution at the required temperature throughout the process.

 3.Anodizing production lines often include waste treatment systems to handle and treat the waste generated during the anodizing process.

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 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

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. 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
