High Capacity Anodizing Production Line with 300d/m x 20h/d Working Hour
一.Product Description
1.Modern anodizing lines adopt functions such as closed-loop water circulation, flue gas extraction, and wastewater treatment systems to minimize environmental impact and comply with relevant regulations.
2.The production line is equipped with advanced process control systems and sensors to continuously monitor and adjust parameters such as temperature, pH value, and current density, ensuring consistent and high-quality results.
3.The aluminum anodizing line is highly automated, using a robotic material handling system to move parts between various process tanks and stations, improving efficiency, consistency, and worker safety.

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 4tanks = 8jig(rack)
(2) Current density: 130A/m²
(3) Process time: 30min
(4) Unprocess time: 10min
(5) Total time 30+10=40min
(6) Average anodizing layer : 0.3*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 4 tank x 60min/h) ÷40min x600 hour =7200jig(rack)
2) Design 50m²/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 7200jig(rack)x 50m² /jig =360000m²
2. Anodizing treatment weight:
Monthly output : 360000m²÷350m²/T*0.9=925T≧900T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =4unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =2unit
