What tolerance can I realistically expect on a formed part?

With our modern CNC press brakes, we can typically hold bend angle tolerances of ±0.5 degrees and linear dimension tolerances of ±0.010" to ±0.020", depending on the material and thickness.

Does the type of metal change how tightly it can be formed?

Yes. Softer materials like 5052 aluminum can be bent to tighter radii without cracking. Harder materials like 6061-T6 aluminum or heavy-gauge stainless steel require larger bend radii to prevent fracturing along the bend line.

What's the difference between powder coating and other finishes?

Powder coating provides a thicker, more durable, and more scratch-resistant finish than traditional wet paint. It's applied electrostatically as a dry powder and then cured under heat, making it ideal for formed parts that will see harsh environments.

How many bends can be done in a single setup?

Our multi-axis press brakes can perform numerous complex bends in a single handling, often completing 6 to 10+ bends on a single part sequentially, which drastically reduces production time and cost.

Understanding Bend Tolerances Before You Submit a Forming Job

Forming metal isn't as simple as folding paper. When a press brake bends a piece of sheet metal, the material stretches on the outside of the bend and compresses on the inside. Understanding how this affects your final part dimensions is critical for successful design.

Bend Allowance and Deduction

To get an accurate final dimension, you must account for bend allowance (the amount of material consumed by the bend) and bend deduction (the difference between the sum of the flange lengths and the flat pattern length). These values change based on material type, thickness, and the inside bend radius.

The Springback Effect

After the press brake releases pressure, the metal will naturally spring back slightly toward its original flat shape. Harder materials like stainless steel exhibit more springback than softer materials like aluminum. Our advanced Trumpf press brakes automatically calculate and compensate for springback, but it's a factor engineers must be aware of.

Designing for Manufacturability

To avoid rework, ensure your inside bend radius is at least equal to the material thickness (ideally larger). Keep holes and cutouts away from the bend line to prevent them from distorting during the forming process. A good rule of thumb is to keep features at least 2.5 times the material thickness plus the bend radius away from the bend line.
