Aluminum plates are easy to break after bending and will burst after anodizing. There will be a lot of confusion among many manufacturers. How to effectively prevent aluminum plates from breaking? Let's understand the main causes and preventive measures for aluminum plate breakage after bending.
1. Hardness of aluminum plate
The hardness of the aluminum plate is too high and it breaks easily. This requires choosing a good aluminum material, mainly based on the grade and condition of the aluminum. Commonly used ones are 1 series, 3 series and 5 series; 6 series and 7 series are too hard. After annealing to the O state, good bending is required. In addition, there is the quality of the aluminum plate. The same type of imported aluminum plate material is less likely to crack than domestic materials, but the price of the material is also very expensive.
2.Thickness of aluminum plate
Aluminum plates that are too thick are not easy to bend. As long as you want to understand, try to use a thin aluminum plate.
3. The size of the bending R angle
The larger the bending angle R, the higher the success rate, and the larger the R angle, the better.
4. Aluminum plate direction
The bending direction should be perpendicular to the direction of the aluminum plate and not parallel.
5. It is best to draw after the bending process, otherwise it will increase the possibility of bending fracture.
