Advantages of Sheet Metal Bending
Accuracy: Programmed laser cutters and CNC bending machines with high-quality software, as well as top-notch equipment, can produce accurate bends.
No tooling investment: The laser cutting and sheet metal bending processes don't require specialised tooling, as common tools usually can produce the desired bends. This means limited tooling investment.
Speed of manufacture: Sheet metal parts can be produced fast, enabling big quantities of components to be produced in a short space of time.
Fewer parts required: Making a workpiece from one piece of material instead of multiple, through the use of joints, reduces time, errors, complexity, and failure points.
Less weight: There is a complex range of bends available. Strength can be achieved without the need for too much material. This reduces weight, which is an advantage for every step in the supply chain.
Lower costs: CNC cutting, laser cutting and bending cut down on the manual labour required, and parts can therefore be made by less-skilled workers, leading to lower-end costs.
Steel
Steel is a very versatile metal that consists of iron and carbon. Steel is economical and has great strength and durability. There are a range of different steels that can be bent including mild steel and stainless steel. Mild steel is easily bent and used widely, including in a range of automotive applications.
Aluminum
Aluminum is a lightweight and cost-effective metal used in the aerospace, electronics, and automotive industries. Aluminum is easy to fabricate and benefits from a high strength-to-weight ratio and high corrosion resistance.
Copper
Copper is a soft metal that allows it to be easily bent and formed. It is also highly conductive, making it perfect for electrical applications. Copper is also naturally antimicrobial and recyclable.
Brass
Brass is an alloy consisting of zinc and copper. Brass is used a lot in sheet metal bending because of its aesthetic appeal and ease of fabrication. Because of its aesthetic appeal, it is used in decorative applications including: Home hardware, architecture, and instruments. Brass benefits from high machinability, low friction, and corrosion resistance.
Stainless steel
Stainless steel, like regular mild steel, is made of iron and carbon, but with the addition of chromium and nickel. Due to the extra chromium and nickel, stainless steel is also harder and work hardens as it bends. This means that stainless steel usually requires a press brake rather than bending by hand. Stainless steel, which uses chromium to protect against degradation, is used in medical and food processing equipment.
Galvanized steel
Galvanized steel, like stainless steel, is highly corrosion-resistant. This is because galvanized steel has a zinc coating. In addition to having an improved service life, galvanized steel components are lower cost than other forms of corrosion-protected steel.
6 Sheet Metal Bending Methods
Method #1 V-bending
V-bending is the most common sheet metal bending method. As its name implies, the v-bending method employs a v-shaped die and a punch to bend metals at desired angles. The v-shaped punch forces the sheet metal workpiece into the “v-shaped” groove in the die, forming sheet metals with different bend angles. For example, you can achieve acute, obtuse, or 90° bend angles, depending on the v-shaped punch and die angle.
Method #2 Air Bending
Air bending is quite similar to the V-bending method: it relies on v-shaped punch and die to bend sheet metals. However, unlike the conventional v-bending process, the punch in the air bending method does not force the sheet into the bottom of the cavity. Instead, it leaves space (or air) underneath the sheet, allowing more bend angle control than conventional v-bending.
Method #3 Bottoming
Bottoming (or bottom bending) is a type of v-bending that also solves the springback challenge. It involves deforming the sheet metal in the bend region by applying additional force through the tip of the punch after completion of bending.
Method #4 Wipe Bending
In the wipe bending method, the sheet metal is held against a wipe die by a pressure pad. The punch then forces against the edge of the sheet that extends beyond the die and pressure pad, causing it to bend over the end of the die.
Method #5 Roll Bending
The roll bending method allows you to bend sheet metals into rolls, tubes, cones, or curved shapes. This unique sheet metal forming process uses sets of rollers that feed (and bend) the metal stock to the desired curvature.
Method #6 Rotary Draw Bending
In rotary draw bending, the sheet metal is clamped to a rotating die and drawn around the die to form a geometry whose radius matches the desired bend radius. This method often employs an internal supporting mandrel to prevent wrinkling on the wall of the bent sheet metal.

Applications of Sheet Metal Bending
Sheet Metal Fabrication: Involves bending sheet metal using universal dies and a press brake. This method offers precise control over bend angles and lengths.
Press Operations: Utilizes dedicated dies and a press machine to shape metal components. Common products include kitchenware, metal sieves, and badge pins.
Roll Forming: Shapes metal sheets by passing them through alternating sets of three rolls, producing large-radius curves. This process is used in manufacturing large cylindrical structures.
Tank Manufacturing: Fabricates tanks, ducts, and support structures.
