Product Description

Sheet Metal Applications

Sheet metal is a versatile manufacturing process for a range of metal components.

The process can support high-volume commodity products and low-volume, one-of-a-kind applications.

Common sheet metal parts include:

1. Electrical enclosure
2. Parts for computer electronics
3. Chassis
4. Brackets
5. Cabinets
6. Mounts
7. Appliances

Bending for sheet metal fabrication

This section focuses exclusively on the best practices for sheet metal bending — one of our core sheet metal fabrication services.
 
We'll start with key general design considerations specific to sheet metal parts intended for bending, then dive deep into the essential best practices to optimize your designs specifically for the bending process.

Wall Thickness

Tolerances

Since sheet metal parts are made from a single metal sheet, the part must maintain uniform wall thickness throughout.
 
We recommend a sheet metal thickness range of 0.5–18 mm (0.02–0.7087 in) for laser cutting, and 0.5–20 mm (0.02–0.7874 in) for bending.

Sheet metal fabrication tolerances are often slightly larger than those of CNC machining. This is because material stretching can occur during bending.
It's important to note that the more processes a part goes through—such as having multiple bends—the harder it becomes to achieve tight tolerances.
We provide the tolerances shown on the right, which are widely accepted in the industry. While tighter tolerances can be achieved, extremely tight ones will increase process difficulty and significantly raise costs.

Hole Placement Guidelines

K-Factor Considerations for Bending

Interior Bend Radius Guidelines

Keep holes at least 2× the sheet thickness away from the bend radius start.

If the hole is placed too close to the bend, it may become distorted or act as an unintended relief cut.

Account for K-factor to prevent deformation and tearing.

When bending metal, the material stretches—this shifts the neutral axis away from the center. To design an accurate flat pattern and determine the correct bend allowance, calculate the K-factor to locate the neutral axis along the bend. 

Keep interior bend radii at least equal to material thickness.
When bending sheet metal, a completely sharp corner can't be achieved—there will always be a slight curve, known as the bend radius.
To avoid distortion around the bend, design parts so the interior bend radius is equal to or larger than the material thickness.

Use consistent radii and bend orientations to cut costs.

Add bend reliefs to prevent tearing and reduce springback

Material on both sides of the bend builds stress, causing deformation or tearing.

Inconsistent orientations and varying radii require more part reorientations, taking more machinist time.
Consistent radii and orientations reduce reorientations, saving time and costs.

Material on both sides of the bend builds stress, causing deformation or tearing.

Relief cuts/bend reliefs relieve stress, boost stiffness and reduce sheet metal springback.

For relief cuts, add incisions on both sides of the bend (at least material thickness wide)

Relief cuts/bend reliefs relieve stress, boost stiffness and reduce sheet metal springback.

For relief cuts, add incisions on bend sides (min. material thickness wide).

Advantages of Sheet Metal Fabrication

The sheet metal fabrication process stands out as an ideal solution for manufacturing metal components, seamlessly accommodating both prototyping needs and full-scale production volumes.

1. Minimal material waste
2. Cost-effective scalability for production volumes
3. Diverse finishing options, such as anodizing and powder coating
