150 T /mAluminum anodizing production line for oxidation surface
treatment
一.Product Description:
1.Anodizing production lines are implementing automated, inline
defect detection systems, such as computer vision and machine
learning-based inspections, to identify and sort parts with
defects, improving quality and yield.
2.Anodizing production lines are integrating with enterprise-wide
ERP systems to streamline business operations, optimize resource
utilization, and improve overall efficiency and responsiveness
across the organization.

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) 2 jig(rack)/tank x 1tanks = 2jig(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:
( 2 rack x 1 tank x 60min/h) ÷40min x600 hour =1800jig(rack)
2) Design 42.9m²/jig(rack) . Where every tank is 85.8m²
3) Area treatment/year : 1800jig(rack)x 42.9m² /jig =77220m²
2. Anodizing treatment weight:
Monthly output : 77220m²÷400m²/T*0.9=174T≧150T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =1unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =1 unit
