Flexibility 550T/Month Automated Anodizing Line Horizontal
一.Description
1.An automated anodizing production line often includes rack and
fixture systems to hold the metal products during the anodizing
process.
2.Automation in an anodizing production line can include real-time
process monitoring and feedback mechanisms.
3.Automated anodizing production lines often incorporate
energy-saving features.

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 3tanks = 6jig(rack)
(2) Current density: 130A/m²
(3) Process time: 30min
(4) Unprocess time: 8min
(5) Total time 30+8=38min
(6) Average anodizing layer : 0.36*0.77*1.3*30 =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 38min ,where total jig(rack)/year:
( 2 rack x 3 tank x 60min/h) ÷38min x600 hour =5684jig(rack)
2) Design 44.3m²/jig(rack) . Where every tank is 88m²
3) Area treatment/year : 5684jig(rack)x 44.3m² /jig =251801m²
2. Anodizing treatment weight:
Monthly output : 251801m²÷400m²/T*0.9=566T≧550T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =3unit
2) Clouring tank: 100㎡/tank×80A/m²÷0.9 = 8888A/tank
Colour Rectifier : 12000A =1 unit
