What Is Sheet Metal Fabrication

Sheet metal fabrication(here we introduce the No-mold way) is a manufacturing process way that involves metal cutting and bending to form different metal shapes products.

There are mainly 3 processing ways for sheet metal fabrication, Include cutting, punching, and bending. These ways can be used either in tandem or individually.

  • Cutting: Usually, Laser Cutting, Waterjet Cutting, and Plasma Cutting services are used for sheet metal processing.
  • Punching: The equipment of the punching process is a punching machine, which can further process the cut material into shape. A lot of parts require specific perforations or patterns, such as ribs, shutters, or countersinks. To this end, CNC punching machines use specific tools to “beat” the metal plate and perforate or shape it in a specific way.
  • Bending: Bending is the last step of sheet metal forming. They can bend or roll the metal sheet into the required shape, which is the forming process of parts; the process of cold pressing the metal sheet by the upper and lower knives of the bending machine to deform the metal sheet to obtain the required shape.

Except for sheet metal cutting and bending, sheet metal processing is also involves welding, assembly, and surface finishes.
