High quality and large capacity 1000T/M anodizing production line
一.Production Description
1.Anodizing creates a protective oxide layer on the aluminum
surface, making it highly resistant to corrosion from moisture,
chemicals, and other environmental factors.
2.The anodized layer is much harder and more scratch-resistant than
regular aluminum, improving the lifespan and performance of
components in high-wear applications like automotive parts,
cookware, and outdoor gear.
3.Anodizing allows for a wide range of color options and finishes,
from matte to glossy, enabling designers to tailor the aesthetic
for various consumer and industrial products.

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*0.9=1157.1T≧1000T
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
