Output 3000 Ton Automated Anodizing Line Aluminium Alloy Profile
一.Description
1.Anodizing is an electrochemical process that enhances the surface properties of metal by creating a protective oxide layer.
2.The automated line incorporates various features to streamline the anodizing process and improve efficiency.
3.An automated anodizing line is a fully integrated system used for the anodizing of metal parts or components in an industrial setting.
4.It is designed to streamline the anodizing process, increase efficiency, and maintain consistent quality throughout production. The line consists of various components and stages that work together to achieve the desired anodized finish.
二.Feature
1.Pre-treatment Zone:An automated anodizing line often begins with a pre-treatment zone where the metal parts undergo cleaning and surface preparation. This may involve processes such as degreasing, etching, and descaling to remove contaminants and improve the adhesion of the anodizing layer.
2.Control System:An automated anodizing line features a control system that monitors and regulates various parameters throughout the process.
3.Quality Control: An automated anodizing line may incorporate quality control measures such as automated inspection systems or sensors to detect any defects or inconsistencies in the anodized surface.

五.Treatment Process:
(6) Average anodizing layer : 0.36*1.3*26*0.77 =9.4um
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
六. 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
