Sheet Metal Bending

Sheet metal bending 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.

Sheet Metal Bending Process

The process of 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.

V-bending

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

Bottom bending

This method requires a higher tonnage press to achieve precise bend angle control.

Customized Shape 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.

Materials of sheet metal bending parts. Those bending metal plates include SGCC galvanized plate, SECC electrolytic plate, SUS stainless steel (model 201 304 316, etc.), SPCC iron plate, white copper, red copper, AL aluminum plate (model 5052 6061, etc.), SPTE, spring steel, manganese steel.

As a professional china sheet metal bending company, TOSTA Metal Fabrication offers a wide range of sheet metal bending services. We can provide you with custom sheet metal bending prototypes or designs according to your specific projects and needs.

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.

With our experienced workers, professional sheet metal bending service and multifunctional metal bending machine we can bend sheet metal panel from materials to custom-desired sheet metal bending parts in any shapes and radii you need.

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.
