Metal Processes

Sheet Metal Bending

-A piece of sheet metal is placed into the bending machine.

-The sheet is placed into the v shaped die below the punch.

-The punch presses down and bends the material into a certain shape.

-The angle of the bend is determined by how far the punch moves.

-Metal up to 10mm thick can be bent cold on these machines.



CAD Plasma Arc Cutting

-Components are drawn in a CAD program such as Pro-Desktop.

-A nesting program is used to arrange the designs in a way which creates least waste.

-The designs are sent to the machine in DXF form.

-It cuts the material using a plasma-cutting torch.


-This is used to cut out sheet metal shapes for welded boxes etc.
