Customization automatic vertical 300 Ton/Month aluminum anodizing production line
Customization 300T automatic Anodizing Production Line
一.Production Description
1.Variations in the thickness of the anodized layer can affect corrosion resistance and appearance.
2.Aluminum anodizing is an electrochemical process that converts the surface of aluminum into a decorative, durable, and corrosion-resistant anodic oxide finish
3.The process involves immersing the aluminum part in an electrolytic solution, typically containing sulfuric or chromic acid, and passing an electric current through it
二. Design Condition
| 1 | Alloy | Aluminium 6061 to 6063 or others |

| 6 | Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 | 3 Tank |
四. Treatment Process:
(6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um
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:
( 2rack x 5 tank x 60min/h) ÷40min x600 hour =9000jig(rack)
2) Design 50m²/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 9000jig(rack)x 50m² /jig =450000m²
2. Anodizing treatment weight:
Monthly output : 450000m²÷350m²/T*0.3=385T≧300T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =5unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =2 unit
