Anodic oxidation process of aluminum products

[China Aluminum Industry Network] The common process flow for anodizing aluminum products is as follows:

Aluminium workpiece → on the rack → degreasing → washing → alkaline etching → water washing → light → washing → anodizing → water washing → deionized water washing → staining or electrolytic coloring → water washing → deionized water washing → closed → washing → under the rack for the requirements of high light Bright aluminum products can adopt the following process flow:

Aluminum workpiece → Mechanical polishing → Degreasing → Washing → Neutralization → Washing → Chemical or electrochemical polishing → Washing → Anodizing → Washing → Deionized water washing → Dyeing or electrolytic coloring → Washing → Deionized water washing → Sealing → Washing → Mechanical light
