2mm Sheet Metal Bend Radius

In steel between 0 5 and 0 8 in.

2mm sheet metal bend radius. The minimum inside bend radius is even larger when bending with the grain. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. When the sheet metal is bent a bend radius is required at the bend.

In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. The problem with bending too tightly.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Let s say i have a 2 mm thick sheet and i want to bend it. To keep it simple i also use a 2 mm inside radius. The material thickness will be measured in decimal form not by the gauge number.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may. Use this document to choose values that are both manufacturable and meet your needs. Discover all our calculation tools in the calculators section of the top menu.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. It s true that the harder and thicker the plate is the greater the minimum bend radius. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form.

This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. The required die width is 12 mm and tonnage per meter is 22. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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.

The bending radius should not be too large or too small and should be chosen appropriately. Bend radii minimum bend sizes. If you re bending 0 020 thick material use a 0 020 radius. If a piece of material is bent too tightly problems can occur.

The most common problem with bending a piece of sheet metal too tightly is.
