We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Minimum radius on bending 6mm steel sheet.
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 minimum inside bend radius is even larger when bending with the grain.
By multiplying the material thickness by 0 63 63 percent the natural minimum radius can be determined in this case 0 063 in.
Let s say i have a 2 mm thick sheet and i want to bend it.
These dimensions are all in relation to a 90 angle.
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.
Bend radii minimum bend sizes.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
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 require a minimum bend radius that s 3 75 times the material thickness see figure 1.
Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
If a piece of material is bent too tightly problems can occur.
Maximum dimensions are 2980 x 1200 mm.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
Maximum weight is 40 kg.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
Maximum sheet thickness for all other steel is 6 mm.
In steel between 0 5 and 0 8 in.
Picture a sheet of 0 100 in thick material 2 54 mm.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
Discover all our calculation tools in the calculators section of the top menu.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
In principle does not seem that this operation is complicated and difficult.
The problem with bending too tightly.
To keep it simple i also use a 2 mm inside radius.
Use this document to choose values that are both manufacturable and meet your needs.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
