  1. Sheet Metal Bending. Sheet metal is bent into the desired shape by applying bending stress. The sheet metal is bent so metal deformation is reached. That prevents the metal from regaining its former shape.
  2. Sheet Metal Curling. Curling is the process of forming a circular ring at the edge of the metal sheet to make it safer for handling. Curling can also be classified into an off-centre and an on-centre roll. Off-centre rolls have the centre above the level of the sheet, whereas on-centre rolls have the centre at the same level as that of the metal sheet.
  3. Deep Drawing. Deep drawing is a sheet metal forming process in which a sheet’s shape is changed to the desired shape in multiple stages using a series of dies. Punches and dies are used to create changes at every stage. Using this process, a sheet is converted into many different shapes like a fuel tank, sink, and automobile parts. Deep drawing is mostly used for large-batch
  4. Hydro-Forming. the metal is placed on a die, high-pressure fluid is used to shape the sheet. Since matching dies are generally not needed, hydro-forming can be used to form unconventional shapes.
  5. Laser Cutting. It is precise and the finish is extremely smooth. CNC machines are generally used to cut specific shapes. After feeding the program, the specific cut is carried out by laser. Laser cutting has the advantage of flexibility. When needed, changes in the required shape can be carried out easily.
  6. Punching. It is a very common technique for cutting holes in sheet metal. The setup consists of a punch and a punching die. There is a very small clearance between the two.
  7. Rolling. It is classified as hot rolling or cold rolling. In hot rolling, the temperature is around 1400 degrees Fahrenheit for steel. This can help achieve a thickness from 1/16th of an inch to 5/16th of an inch. In cold rolling, the process is carried out at room temperature. The material is washed with acid and heat treated to achieve a good finish.
  8. Press Brake Forming. It’s used for smaller parts making it suitable for smaller pieces along with large pieces. Thickness up to 25 mm can be easily bent and the length of the piece can go up to 6 m.
  9. Wheeling. Wheeling is mainly used in producing low-volume customized parts for old vehicles. It is also used for creating sheet metal parts for car prototypes and aircraft.
