Power Automated Anodizing Line Process Horizontal Anodiding line
一. Product Description
Semi automatic given control system
(1) The start and stop of the oxidation power supply can be
controlled by the PLC of manual or automated production lines;
(2) PLC sets oxidation working time timer or automated production
line;
(3) The output current or voltage value and operating process of
the power supply are set by the production line PLC and central
control system;
(4) The operating parameters and status can be transmitted to the
upper computer of the production line through a communication
interface;
(5) Pre set values can be set according to the process and provided
parameters.

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
六. 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
