Punching is a metal fabrication process that removes a section of metal from a sheet or plate by applying high force using a punch-and-die system. It’s commonly used to create holes, notches, slots, or decorative patterns—and it’s known for being fast, repeatable, and cost-efficient in high-volume production.
