Sheet Metal Fabrication
Sheet metal fabrication refers to multiple processes that alter a metal sheet’s original shape to produce desired parts and products. The manufacturing steps are procedural and must incorporate the right processes to give out a desired final product.
Types of Sheet Metal Fabrication Materials
There are numerous types of sheet metals available that are suitable for various fabrication processes. The primary metals available include:
- Steel – all four classifications of steel are prominent for robust strength, ductility, and resistance to corrosion
- Aluminum – a relatively lightweight metal with high strength
- Magnesium – a shiny, lightweight, and strong metal with low density making it adequate for structures that require stiffness
- Bronze – a very high ductile metal with a low melting point
- Copper – a soft and malleable metal with heat and electrical conductivity
What is the Sheet Metal Fabrication Process?
There are three primary steps in the fabrication process. Following each process guarantees the production of high-quality final products.
The cutting process is complex and depends on the type of material. Also, the preferred final product plays a crucial role in the selection of the cutting process. The main cutting processes include:
- Mechanical cutting
- Laser cutting
- Waterjet cutting
It is the process of bending the sheet metal into desired shapes. The manufacturer uses methods like air bending, roll forming, and coining in this process.
Joining is the process of assembling together different components of the metal to achieve the desired product. This process can include welding (MIG, TIG, laser welding, spotwelding), riveting, or the use of hardware fasteners.
