Bending your metal parts adds a $9.00 minimum to your cart total. Pricing starts at $2 per bend once you’ve met the minimum charge. See our handy chart below for examples.
| # of Parts | # of Bends per part | Total Cost | The Math |
| 1 | 2 | $9.00 | $2 per bend x 2 bends x 1 part = $4 ($9.00 minimum used) |
| 2 | 2 | $9.00 | $2 per bend x 2 bends x 2 parts = $6.40 (20% part qty discount, $9.00 minimum used) |
| 10 | 2 | $24.00 | $2 per bend x 2 bends x 10 parts = $24 (40% part qty discount) |
| 50 | 2 | $100.00 | $2 per bend x 2 bends x 30 parts = $100 (50% part qty discount) |
For shipping, please allow for an additional 3-5 business days (100 pieces or more may require additional time). Most bent parts will ship ground as they will exceed 2″ in height when packed.
Before you start dreaming up your next project, you’ll need to know some of the limitations to metal bending.
While we’re happy to bend your parts to your hearts’ desire, there are some bends we don’t offer:
While our effective bend radius for our materials ranges from .024″ – .250″, the dies we use will span at least .472″ -1.575″ across the bend line. We cannot offer cosmetic protections along the die lines, so holes, edges, and other cutouts are subject to distorting in the bend process. Check out each material page to see what die we will use for your material of choice, and make sure your cut features are at least half the die’s width away from the bend line.
Here are the basics you’ll need to know before you send us your first file for bending. If you have any questions, feel free to contact support.
Make sure the file you upload for bending is a flat, 2D file. You will be able to view your bends in a 3D model during the checkout process to make sure the angles and flange orientations are correct.
| SOFTWARE | FORMAT | BEND LINE |
| Fusion360 | .dxf | Solid line (default) |
| Adobe Illustrator | .ai | Solid, separate color from cut lines |
| Solidworks | .dxf | Dashed line (default) |
| AutoCAD | .dxf | Dashed line |
| CorelDraw | .eps | Solid, separate color from cut lines |
| Inkscape | .eps | Solid, separate color from cut lines |
Please upload a “flat” .DXF, .AI or EPS as you normally would. We do not require a 3D file for bending, although you are encouraged to attach a PDF or image preview to your order to help us understand your project.
If you design your parts in non-CAD software (Adobe Illustrator), please send us the original (native) ai file. We’ll take care of the conversion on our end. While we accept .AI and .EPS files, it’s critical that your bend lines are parallel when uploaded from these softwares or the file will delay our process.
For the fastest turnaround on your order, we recommend designing your parts in a CAD software.
To learn more about design guidelines for laser-cutting, please see our Laser Cutting Guidelines.
The minimum and maximum flange length will change depending on what material and thickness you use. Please reference your chosen material in our materials directory to see the correct dimensions.
The example here is the bending information for .040″ 5052 Aluminum.
Bend Deduction is used to counteract material stretch caused by forming. This is unique to each material type, thickness, and bend angle. We’ve created a calculator to help you make your measurements spot on.
Advanced-user note: All calculations should be for air bending, not coining.
Once you have your new measurements from the bend calculator, you’ll want to adjust your file accordingly. You will be reducing the length of your base and flange to accommodate the length of the bend itself, aka the bend deduction. See the illustration below for an example. The green line indicates where the bends will occur.
The bend angle is measured on the outside of the bend. In the illustration below, you will see that the acute bend is being called out as 130°. Note: the bend radius for your part can be found on the material page or the bending calculator. We do not offer a custom bend radius.
To reduce bulging in the corners of your bent parts and prevent tearing, you can incorporate bend relief notches into your design. Bend relief notches are just narrow notches or circles put into the corners of your design. These notches should be at least 50% of the material’s thickness in width and the depth should equal to Bend radius + Material thickness +.020”. These notches allow for less stress on the inner radii of the flanges, and will help keep the corners of the bends from interfering with the base material. Check out our guide to designing bend reliefs.
While we do allow for irregular shapes for your flange, we will need a flat piece to bend. To do this, add tabs to make a flat surface parallel to the bend.
Take a look at the example below. The irregular shape is still attached to the flat area and will be removed upon receiving parts.
If two bend lines are in line and nearly touching they will automatically be combined into a single line in the SendCutSend app. The app will flag which lines have been combined into one bend.
We are unable to bend intersecting lines that do not have separate flanges. Please reference the bending design guidelines.
Certain designs require bend relief to avoid damage to the part. Without proper relief, a part cannot be bent accurately. Check out our guide to designing bend reliefs.
Although metal forming is a deeply complex process, we here at SendCutSend aim to make part bending as easy as possible. Questions? Email us anytime: support@sendcutsend.com
