Top 6 Common Process Of Sheet Metal Forming

Sheet metal, which is made up of thin, flat slabs of metal, usually made of steel or aluminum, is crucial to the industrial and construction sectors. It is utilized in the construction industry as panels for homes and structures. Sheet metal is utilized in the manufacturing sector for a variety of things, including floors, large machinery, and vehicle parts.

The common process of sheet metal forming

When making sheet metal, companies must use these 6 important forming processes.


The sharp and jagged edges of sheet metal are smoothed out by the sheet metal manufacturing process called curling. After being made, sheet metal frequently has “burrs” along its sharp edges. Deburring sheet metal to create smooth edges is a step in the forming process known as curling.


Bending is yet another typical sheet metal forming procedure. Businesses often use a brake press or another type of machine press to bend sheet metal. 

A punch then applies pressure to the sheet metal after it is laid over a die block. Actually, bending doesn’t make holes in sheet metal. Instead, it fulfills the meaning of its name by “bending” sheet metal into the die’s shape.


In order to achieve a consistent thickness, sheet metal can also be ironed. For instance, ironed aluminum is used to make the majority of aluminum cans. The aluminum sheet metal is ironed to make it thinner and more consistent because it is too thick in its raw form for beverage cans. In order to iron metal, a punch is used to press the metal between two dies.

laser cutting

Manufacturers of precision sheet metal components claim that in recent years, laser cutting has become a more widely used method of sheet metal shaping. When sheet metal is cut with a laser, a strong laser is used to burn holes into the metal. 

Using a computer numerically controlled (CNC) laser cutting equipment is a quicker and more accurate cutting technique that can even be carried out automatically.


Hydroforming is a less well-known method of sheet metal forming. Hydroforming requires stretching the blank over a die, just as deep drawing. What distinguishes deep drawing from hydroforming, then? The main distinction between these two methods is that deep drawing needs several draw reductions, whereas hydroforming only needs one.


Last but not least, punching is a sheet metal forming technique that entails poking holes in the metal with a punch and dies set. Between the punch and die is the sheet of metal. The punch then depresses and penetrates the sheet metal to make a hole.


Globally, sheet metal is widely used and is a crucial component of practically all production industries, including the aerospace, automotive, and food industries.

The applications of forming processes are both numerous and diverse, and they can include more well-known examples like drawing, stamping, or roll forming as well as less well-known examples like explosive and magnetic pulse forming.

A large variety of production parts are used in sheet metal forming for both visible and invisible functions. Metal with a high surface area to volume ratio is referred to as sheet metal. Due to its characteristics, it offers us a huge number of advantages in numerous ways.
