Sheet Metal Bending
Bending metal sheet at home is a forming process. In process of custom sheet metal bending, 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 supplier and we provide custom sheet metal bending services.

What is Sheet Metal Bending?
The process of precision sheet metal bending involves transforming a flat sheet of metal into a V-shaped opening. To achieve this, the workpiece is positioned onto a concave die that has a V-shaped opening. Subsequently, a wedge-shaped tool (knife) applies pressure to the workpiece, pushing it into the V-shaped opening and bending the plate to the desired angle.

HSJ 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.

HSJ Custom Sheet Metal Bending Servies
HSJ offers professional Custom Sheet Metal Bending Services with seven different methods available:

V-bending - this method involves using a v-shaped die and punch to bend sheet metal to achieve acute, obtuse, or 90° bend angles.

Air Bending - leaves space (or air) underneath the sheet, allowing for more bend angle control than conventional v-bending, resulting in higher accuracy due to less springback.

Bottom bending - this method requires a higher tonnage press to achieve precise bend angle control.

Wipe Bending - involves holding the sheet metal against a wipe die via a pressure pad, and using a punch to force the edge of the sheet beyond the die and pressure pad, causing it to bend.

Roll Bending - uses sets of rollers to feed (and bend) the metal stock into rolls, tubes, cones, or curved shapes.

Rotary Draw Bending - the sheet metal is clamped to a rotating die and drawn around the die to form a geometry that matches the desired bend radius, with an internal supporting mandrel to prevent wrinkling on the surface and minimize the risk of scratches.

Customized Shape Bending - HSJ accepts custom one-piece molding requests for high-efficiency production.

How to Control Sheet Metal Bending Tolerances?

In the process of precision metal bending, tolerances are inevitable. Sheet metal bending tolerances within a certain range are allowed.

Our sheet metal bending 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 sheet metal bending tolerances to the smallest possible range.

Therefore, when cutting the material, it is necessary to ensure that the sheet metal bending tolerances 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
What is the application of ours sheet metal bending parts?
The common applications of sheet metal bending parts are in the panels, enclosures, cabinets, etc. of automobiles and airplanes.

How to select materials for precision metal bending?
According to product functional, aesthetic and cost requirement, we choose the appropriate precision metal bending 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 sheet metal panel bending metals include tin, magnesium, cadmium, and aluminum.

As a sheet metal products manufacturer, we will do our best to meet all the needs of customers.
