Perforated aluminum sheets are typically made from durable, lightweight and corrosion resistant high quality aluminum alloy sheets. Perforations can be created using a variety of methods, including stamping, drilling, laser cutting and waterjet cutting.
In the DIY, we carefully place the desired sheet metal into the punching machine. The software controls the spacing, size and position of the holes punched in the sheet metal.
In total industrial production, to produce high quality perforated metal, the entire sheet is loaded onto a turret punch. The machine can then be punched with single die or cluster tools as required, moving through the stationary material section by section.
Typically, a certain amount of material along the length of the sheet will not be perforated. This is done to create margins or plain white spaces around the edges of the material.
