1. Anodizing surface treatment can achieve almost all surface textures, from matte to high gloss. Therefore, countless color options and customization can also be provided.

2. The oxide layer (especially anodized aluminum) can provide electrical insulation for the component, while the internal metal still maintains its conductivity.

3. Anodized coating is a type of hard oxide coating that can improve hardness, wear resistance, and corrosion resistance. It covers all sharp corners, edges, and complex areas

四. Treatment Process:

Degreasing
(1) 6jig(rack)/ tank x 1 tank=6jig(rack)
(2) treatment time: 2-5min
Alkaline Etching
(1) 6jig(rack) / tank x 2 tank=12jig(rack)
(2) treatment time: 3-15min
Neutralization
(1) 6jig(rack) / tank x 1 tank=6jig(rack)
(2) treatment time: 1-5min
Anodizing
(1) 3 jig(rack)/tank x 5tanks = 15jig(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

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:

( 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
