• Material Expertise: Guidance on selecting the optimal sheet metal for formability, strength, corrosion resistance, and cost targets.
• Process Optimization & Simulation: Fine-tuning stamping parameters and tool design using FEA modeling for intricate forms and tight tolerances.
• Rigorous Quality Assurance: Dimensional inspection, material verification, and in-process monitoring to ensure consistent quality across production runs.

It is a process that forms a sheet of metal using a punch and a die. The initial part can be a sheet metal coil or a blank previously cut into a custom shape. See laser and waterjet cutting. Stamping can cut or form sheet metal. It can perform several cuts and bends in a few seconds.

Stamping is widely used in progressive die stamping, a fully automated manufacturing line that transforms sheet metal coils into functional mechanical parts such as enclosures and car bodies. This process is used in automotive manufacturing to fabricate mass-volume car body parts.

Sheet metal components are used in:

   •  Aircraft's bodies
   •  Car's bodies
   •  Consumer electronics
   •  Biomedical
   •  Enclosures
   •  Beverage cans

Generally, sheet metal operations are performed as cold. Norck supplies sheet metal cutting and forming processes such as:

1. Blanking / Punching: Cutting a workpiece from a sheet metal coil using a press (DIE).

The desired result is the difference between blanking and punching (workpiece/scrap).

2. Forming : It comprises multiple operations such as blanking, punching, and bending to form a simple or complex shape of sheet metal components. The sheet metal is transformed between a punch and a DIE with male and female shapes of the final workpiece.

3. Deep drawing : A blank is held between a die and a blank holder, and then it is formed using a punch. The shapes obtained are generally curved parts.

Stamping is typically fabricated using specialized equipment such as stamping or punch press machines. The process can involve several steps, depending on the part's complexity.

  •   Sheet metal cutting: The first step is to cut the sheet metal to the correct size and shape. It uses various methods such as shearing, sawing, or laser cutting.

  •   Loading: The sheet metal is then loaded into the stamping press or punch press machine, which holds the metal in place while the stamping process occurs.

  •   Stamping: The punch, typically a cylindrical or conical shape, is pressed into the die, typically a block with a shaped surface, to cut and shape the metal.
