2mm Aluminium Sheet Bending

After a few wiggles the sheet will fracture along the cut line leaving a clean break as shown in the above photos.

2mm aluminium sheet bending. Move the sheet around inside the brake as needed to align the bend point with the internal edge of the clamp bar the side facing you. The required die width is 12 mm and tonnage per meter is 22. I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. You can also use a craft knife to mark soft metals such as aluminium.

How to bend sheet metal without a brake. Material bend radii and minimum bend size charts please note. Adjust the edge of your sheet to set your desired bend line. With care and patience full size sheets of aluminium can be cut using this method.

The finer the marks the more accurate your bends and cuts will be. This doesn t sound like a lot but when you are drilling four holes to mate up to another piece its important. The section of the sheet beneath the clamp bar will fold up and around this edge to produce the bend. To keep it simple i also use a 2 mm inside radius.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. Let s say i have a 2 mm thick sheet and i want to bend it. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.

Create a long fracture line then progressively bend the sheet from one end to to the other.
