3000T / M Semiautomatic Anodizing Production Line 8-12µm
一. Description
An anodizing production line is a specialized manufacturing system designed for the process of anodizing metal objects, typically aluminum. The purpose of an anodizing production line is to enhance the surface properties of these objects by creating a durable and corrosion-resistant oxide layer on their surfaces.
二.Feature
1.Before anodizing, the metal parts need to go through a pre-treatment process.
2.The anodizing tanks are the central part of the production line. They contain an electrolyte solution, typically sulfuric acid, which acts as an electrolyte.
3.An anodizing production line is equipped with control systems to monitor and regulate various parameters during the process.

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 8tanks = 24jig(rack)
(2) Current density: 130A/m²
(3) Process time: 26min
(4) Unprocess time: 7min
(5) Total time 26+7=33min
(6) Average anodizing layer : 0.36*1.3*26*0.77 =9.4um
- Colour 1
1) Clour process: Mix Salts
2) Quantity:3 jig(rack)/tank x 1tanks = 3jig(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 33min ,where total jig(rack)/year:
( 3 rack x 8 tank x 60min/h) ÷33min x600 hour =26181jig(rack)
2) Design 50m²/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 26181jig(rack)x 50m² /jig =1309050m²
2. Anodizing treatment weight:
Monthly output : 1309050m²÷350m²/T*0.9=3366T≧3000T
3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank
Power Rectifier : 15000A =3unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank
Colour Rectifier : 8000A =3 unit
