550T/Month Automated Anodizing Line 380V - 415V Horizontal Mode

550T/Month Automated Anodizing Line 380V - 415V Horizontal Mode

一.Description

1.An automated anodizing line is a comprehensive system designed for the efficient and consistent anodizing of metal parts or components in an industrial setting.

2.The automated anodizing line typically begins with a pre-treatment stage, where the metal parts undergo cleaning and surface preparation.

3.Once the pre-treatment stage is complete, the parts are transported through a conveyor system to the anodizing tanks.

6. Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 1 Tank 

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 3tanks = 6jig(rack)
   (2) Current density: 130A/m²
   (3) Process time: 30min
   (4) Unprocess time: 8min
   (5) Total time 30+8=38min      

          (6) Average anodizing layer : 0.36*0.77*1.3*30 =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 38min ,where total jig(rack)/year:​

                   ( 2 rack x 3 tank x 60min/h) ÷38min x600 hour =5684jig(rack)

2) Design 44.3m²^/jig(rack) . Where every tank is 88m²
3) Area treatment/year : 5684jig(rack)x 44.3m² /jig =251801m²

2. Anodizing treatment weight:
        Monthly output : 251801m²÷400m²/T*0.9=566T≧550T

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

           Power Rectifier : 15000A =3unit
        2) Clouring tank: 100㎡/tank×80A/m²÷0.9 = 8888A/tank

   Colour Rectifier : 12000A =1 unit
