Process of 05mm anodized aluminium sheet

The fixture for an anodized aluminium sheet is completely different from the hanger for electroplating. It is necessary to use a flexible fixture to clamp the sheet. Only in this way can the anodizing process proceed normally. The structure of the clamp is preferably individual. If it is assembled, the riveted or welded part will be loosened due to corrosion after several uses, which hinders the normal flow of current during the anodizing process. At the same time, the fixture must have a certain cross-sectional area.

During the anodizing process, an oxide film is also generated on the fixture. For this reason, be sure to remove the oxide film before using the used fixture again. Film release can be performed in an aluminum degreasing solution. The oxide film on the part where the fixture is in contact with the workpiece can also be filed off. This method can also extend the life of the fixture for some fixtures.

In addition, it should be noted that the clamps are different, and the clamps have a certain elasticity. Excessive force should be used to prevent an 05mm anodized aluminium sheet from deformation. When the work piece is clamped too loosely, the current between the fixture and the work piece will be turned on and off. In this case, the work piece is likely to be burned.
