What are the core steps of metal bending process?

Metal bending process is the process of plastically deforming metal sheets along a predetermined straight line or curve through mechanical force to finally obtain the desired shape. This technology is widely used in the metal manufacturing industry, especially in sheet metal processing. Common metal bending methods include V-shaped bending, U-shaped bending and Z-shaped bending.

Core steps of bending process

1. Material preparation
To make sure the material thickness satisfies the bending requirements, choose appropriate metal sheets, such as carbon steel, aluminum, stainless steel, etc.

2. Mold selection
Make use of a specialized bending mold, which is often made comprised of upper and lower molds and a bending machine. The shape and bending angle are taken into consideration when choosing different molds.

3.Compute the bending force
Calculate the required bending force based on the thickness of the sheet, the bending angle and the radius of the mold. The size of the force determines the bending effect. Too large or too small will cause the workpiece to deform unqualified.

4. Bending procedure
The sheet is plastically deformed along the mold's shape to take on the necessary shape and angle by applying pressure through the CNC bending machine.

5. Post-processing
To guarantee that the final product satisfies quality standards, the workpiece could require surface treatments like polishing, deburring, etc. after bending.

Commonly used equipment includes CNC bending machines and hydraulic bending machines.
