Instant Manufacturability Checks for Fabricated Sheet Metal

When you upload your design, our system will automatically check your fabricated metal part for manufacturability.  You can learn more about design rules on our Bending Design Rules page.

Our online app will give you instant manufacturability results, checking for:


1) Bend relief

2) Flange length

3) Part collision (eg. will it bend to the desired shape without colliding with itself?)

4) Brake and tooling collision

1. Bend Relief

When you bend your part

2. Flange Length

The finished size of your bent part will depend on the bend radius, k-factor, and the location of your bend line.

When bending your part, we will place the punch EXACTLY on the bend line in your drawing. 

If the finished size of your part is important, the best way to make sure your part is the right size is to design your part in CAD software like Fusion 360, using the bend radius and k-factor information published in our material catalog.  When CAD software unfolds your 3D model to create the flat pattern, it will use the k-factor and radius information you provide to make sure things are sized properly.

You can learn more on our design rules page.

3. Part Collision

The bend angle is defined from the perspective of the punch.  So, a 135 degree bend leaves an obtuse angle on the bent part, and a 45 degree bend is an acute angle from the perspective of the punch.  Be sure to review the 3D view of your part to make sure that it looks correct.

4. Brake and Tooling Collision

We currently do not have equipment to apply finishing operations like graining, deburring, and edge rolling.

As a result, your part may contain shallow, cosmetic scratching and small edge burrs, particularly on the bottom side of the cut edge.  We are working on expanding our capabilities to include finishing operations, but for now, if you need pristine parts, we recommend that you find a full-service fabrication shop that can provide clean, scratch-free parts.
