Problems solved by technology

[0018] As the cause of uneven anodization, the temperature of the electrolyte, current density, electrolysis voltage, etc. will have an influence, and it may be that the surface temperature of the roll-shaped aluminum is uneven, and the current-carrying member for supplying a stable current is not in close contact with the aluminum substrate. Poor power supply due to ground contact
