Tolerances – Material
> Material – Thickness
At LaserBoost, we use top-quality materials from leading manufacturers in Northern Europe. Our material suppliers comply with ISO and EN standards for the supply of flat metal materials. The following table shows the specific standard that applies to each material.
Material

Aluminum
IN 485
Stainless Steel

The material thickness can be affected by the finishes we offer. Below, we show the estimated value of thickness loss according to each finish:
Finish

The thickness loss values for finishes with a “High” effect on the material can be up to 30% higher than those shown for soft materials such as Aluminum, Copper, or Brass.

The shown tolerances will be met as long as the guidelines for flat laser cutting and the guidelines for laser cutting with bending are followed.
> Laser Cutting – Minimum perforations
For a proper cut, we require that all perforations have a minimum diameter.

In aluminum, the value of Esperor (t) is equal to the value of the minimum diameter (d).
> Laser Cutting – Minimum Bridges and Distance to the Nearest Vertices
To avoid burns or irregularities in the narrow areas of the part, we need them to meet a minimum distance. This also applies to the minimum distance between the cutouts and the outer edge of the part.

> Other considerations about laser cutting
Heat-induced deformations
Our cutting process subjects the part to high temperatures. A very high cutting density can generate deformations or oscillations in the part. For example, a large-sized grid. More information is available in our design guide for flat laser cutting.
Part flatness
The materials used in LaserBoost comply with European flat rolled supply regulations, including their flatness. However, this may not be directly related to the final flatness of the part, which depends on its length and can be affected by its design or even gravity. For example, a 1mm thick part measuring 2000mm x 5mm may experience a lack of flatness.
Tolerances and Bending Capabilities
> Bending Tolerances
At LaserBoost, we work with the technique of air bending, using punch and die. Below, we show the bending tolerances with some basic shapes as examples. For more complex parts, you need to add the values for each shape present. The tolerance values vary according to the material thickness.

> Bending Radious
At LaserBoost, we require that the exterior radius of the parts be designed with a value two times equal to the thickness of the material (this value is mechanically most optimal). We use the necessary bending tools to reproduce these radii within specific tolerances based on the material thickness. This value is maintained regardless of the angle, from 0º to 180º.

Regarding the User Guides, Tolerances, and Production Capacities of LaserBoost’s service, it is possible to manufacture parts correctly that do not meet the capacities advertised here. However, LaserBoost does not guarantee the correct result of cutting and/or bending if the specifications mentioned on our website are not met. If a design does not meet any of the tolerances, capacities, or limitations announced, it can be produced by LaserBoost at the customer’s risk. You can validate the proper producibility of your design prior to placing the order by contacting our technical team at info@laserboost.com.
