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.

| 6 | Medium Temperature Sealing【PH 5-6.5,Nickel ion0.8-1.3g/l,Fluorion0.3-0.7 g/l】 | 3 Tank |
四. Treatment Process:
(6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um
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
