What Is Sheet Metal Punching?

Sheet metal punching is a forming process that uses a punch press to create holes, shapes, and cutouts in metal sheets. This metalworking process involves:

• Using specialized tooling to create specific shapes
• Removing material through controlled force
• Creating precise holes and patterns
• Processing various metal thicknesses

The punch and die work together to create clean, accurate cuts in the workpiece.

How Does Metal Stamping Compare to Punching?

Metal stamping and punching are related but distinct processes:Stamping:

• Forms shapes without breaking the metal piece
• Creates three-dimensional forms
• Uses dies realizing any kind of shape
• Suitable for complex geometries

Punching:

• Removes material completely
• Creates holes and cutouts
• Uses punch presses and dies
• Focuses on material removal
