1. Press Brakes: Press brakes are used to bend and shape metal sheets into a specific angle or shape. They use a hydraulic or mechanical press to apply pressure to the metal sheet, forcing it to bend and take on the desired shape.

2. Roll Forming Machines: Roll forming machines are used to shape metal sheets into long continuous strips with a specific cross-section shape. The machine uses a series of rollers to gradually bend and shape the metal until it takes on the desired profile.

3. Punching Machines: Punching machines are used to create holes or cutouts in metal sheets. The machine uses a punching tool to apply force to the metal sheet, creating a hole or cutout.

4. Shearing Machines: Shearing machines are used to cut metal sheets into smaller sizes or to separate them from larger sheets. The machine uses a sharp blade to slice through the metal, creating a clean and precise cut.

5. Stamping Machines: Stamping machines are used to create complex shapes and designs by pressing or stamping the metal sheet into a specific shape or pattern. The machine uses a stamping tool to apply force to the metal, creating the desired design.
