MEIAL company Oxidation production line with a monthly output of
1000 tons
一.Production Description
1. The oxidation production line integrates advanced intelligent
maintenance systems, such as predictive and condition-based
monitoring, to proactively anticipate equipment failures and
optimize maintenance schedules.
2. Through the collection and analysis of extensive process data,
oxidation production lines are able to generate detailed reports,
performance dashboards, and make data-driven decisions to enhance
operational efficiency.
3. Collaboration with customers and design teams during the product
development stage ensures optimal part design and material
selection for effective and efficient anodizing within oxidation
production lines.

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
