In the process of Metal Stamping, there are many factors that can affect the quality of stamped parts. The minimum bending radius of stamped parts is very important for the factory. Once the difference is too large or exceeds the requirements, it is a very serious matter for production. Therefore, stamping processing plants will be cautious in processing.

So what are the factors that affect the minimum bending radius of stamped parts? EMAR answers for you:

1. Mechanical properties of the material: The better the plasticity of the stamping material, the higher the plasticity index, and the smaller the minimum bending radius; 2. The connection between the fiber direction of the stamping material and the direction of the bending line: The rolled sheet is anisotropic, and the plasticity index along the fiber direction is higher than the plasticity index along the straight fiber direction; therefore, if the bending bending line is straight in the fiber direction of the sheet, the value of rmin/t is less than the bending line in parallel with the fiber direction. When bending a workpiece with a smaller r/t, try to make the bending line straight in the fiber direction of the sheet to improve the degree of deformation and prevent the outer fiber from cracking; for multi-directional curved workpieces, the bending line can be angled with the fiber direction of the sheet metal.

When you notice these during the metal stamping process, you can largely avoid them.
