What Is Sheet Metal Working & How The Forming Of Sheet Metal Works

Sheet metal is not a specific material. Rather, the term is used for metals that have been formed into shape. As a rule, sheet metal has a rectangular shape. It is also characteristic that the thickness of a sheet is considerably below that of its length and width.

In addition to steel, numerous other metals such as copper, aluminum and gold as well as brass alloys can be processed into sheet metal. In order to be processed into sheet metal, however, the materials used should have specific characteristics, i.e. a certain toughness and rigidity, and of course be ductile, i.e. formable. These requirements result in restrictions with regard to the materials that can be used. Thus, it is not possible to process very brittle or extremely stiff materials into sheet metal.

According to this, sheet metal is a semi-finished product that can be produced over a large area, whereby sheets are generally light, thin, stable, elastic and flat. Due to these specifics, they are suitable for all types of cladding and covering. In addition, sheet metal can be deformed in many ways, i.e. it can be welded, bend, punched or cut. A wide variety of shapes can be made from sheet metal, which is why it is used as the starting material for a wide variety of products.

The term "sheet metal processing" covers a large number of manufacturing processes. Basically, the word sheet metal working refers to the manufacture of products, components and parts made of metal. In addition to welding, cutting and bending, the processes of sheet metal processing also include punching, forming, rolling and joining. Sheet metal forming is usually also included in sheet metal processing, with the following subcategories:

• Welding
• Gluing
• Bending
• Piercing
• Drawing
• Steel construction
• Layer forming
• Heating coil
• Cutting
• Slitting
• Bending punching
• Laser cutting
• Laser processing
Within the framework of sheet metal processing, both soft and resistant sheets can be produced, whereby the different characteristics are achieved by different alloys. For example, there are numerous elements that can be added to steel in the liquid state during metalworking and that determine the material properties of the sheet metal produced. In addition to silicon, nickel and chromium, these elements also include titanium, copper, niobium and molybdenum.

① As machined(standard): ~125 RA µin (3.2 RA µm). Minor tool marks will be visible on the part.
② Smoothed: Parts are machined at a lower feed rate in order to achieve a surface roughness of ~62.5 RA µin (1.6 RA µm). Surface roughness can be decreased up to ~32 RA µin (0.8RAµm) upon request.
③ Bead Blasted: Bead blasting adds a uniform matte or satin surface finish on a machined part, removing all tool marks. Mainly used for aesthetic purposes.
④ Anodized Clear or Color: Anodizing adds a thin, hard, non-conductive ceramic coating on the surface of aluminum parts, increasing their corrosion and wear resistance. Available in a variety of colors.
⑤ Anodized Hardcoat: Hardcoat anodizing produces a thicker ceramic coating providing excellent corrosion and wear resistance. for functional applications.
⑥ Powder Coated: Powder coating adds a thin layer of strong, wear and corrosion resistant protective polymer paint on the surface of a part. Available in a large range of colors.
⑦ Electropolished: Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface surface roughness.
⑧ Black oxide: Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.
⑨ Chromate conversion coating (Alodine/Chemfilm): Chromate conversion coating is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.
⑩ Brushing: Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish.
