Sheet Metal Bending

Sheet metal bending is a forming process in which a metal sheet is passed through a pressure device and a special mold to transform a desired three-dimensional shape by applying bending stress. We are professional sheet metal bending company and we provide the sheet metal bending services.


What is Sheet metal bending process?


The bending, or press brake forming or folding, is a forming process in which the plastic deformation happens over an axis. Bending does not normally change the thickness of the sheet metal.

Punches and dies press brakes are used to perform this process. A die can be a lower V- or U-shaped tool. The plate is pressed into the die to made a bending part. 

The CNC controls of our machines will precisely regulate the lowering depth and helps to maintain the minimum bending radius.

How to control sheet metal bending tolerances?


  • In the process of sheet metal bending, tolerances are inevitable. Tolerances within a certain range are allowed. 

  • Our tolerances are less than 5.0 for sheets of ±0.1 and 5.0 or more for ±0.3.  And those over the range should be caused by improper operation. What we need to do is to control the tolerance to the smallest possible range. 

  • Therefore, when cutting the material, it is necessary to ensure that the tolerance of the plate shearer can be controlled. In addition, shear plates and CNC machining also play a significant role in sheet metal processing.

Sheet Metal Bending Related FAQs

Sheet Metal Bending Related FAQs

  • What is the application of ours bent sheet metal parts?

    The common applications of bent sheet metal parts are in the panels, enclosures, cabinets, etc. of automobiles and airplanes.


  • How to select materials for sheet metal panel bending?

    According to product functional, aesthetic and cost requirement, we choose the appropriate sheet metal materials. After selecting the materials, they should be verified and tested according to the product design requirements.


  • What is sheet metal bend allowance?

    Bend allowance is defined as the material required to add to the total length of the panel metal in order for it to get cut in the required size.


  • What metals can bend well?

    The higher a metal's degree of elasticity is, the greater bend allowance it has. One of the most elastic metals is nickel titanium. The next most elastic metals include tin, magnesium, cadmium, and aluminum.
