Stamping Process for Sheet Metal

Typical Sheet Metal Stamping Procedure

Sheet metal, die, and press machine are the essentially only three parts of sheet metal stamping; however, each part may need more than one step to reach its finished form. Some of the common processes that might happen during metal stamping are explained in the guide below.

• Forming: Forming is the process of using force to change the flat metal into a different shape. It can be done in a few different ways, depending on the part's design requirements. The metal can be transformed from a fairly simple shape into a complex one through a sequence of operations.
• Blanking: The simplest method is called blanking, and it starts with feeding the sheet, or blank, into the press so that the die can cut the desired shape out of it. We refer to the finished product as a blank. The blank could be the desired part—also referred to as a fully finished blank—or it could go on to the next phase, which is forming.
• Drawing: This process, which is more difficult, is how deep depressions or vessels are created. The material is carefully drawn into a cavity using tension to change its shape. Even though the material may stretch while being drawn, technicians make every effort to minimize stretching in order to preserve the material. Drawings are typically used in the construction of oil pans for cars, sinks, and cooking appliances.
• Piercing: Piercing is nearly the reverse of blanking; however, technicians utilize the material surrounding the punched area rather than preserving the blanks. Consider slicing biscuits from a rolled-out circle of dough as an illustration. The biscuits are saved during blanking; however, during piercing, the biscuits are thrown out and the desired result is the remains filled with holes.
