Laser microperforation on acoustic panels: why choose the CO₂ laser

In the production of acoustic panels, laser microperforation has introduced a decisive innovation in the fields of acoustics and interior design. Compared to technologies such as punching, CO2 laser offers specific advantages in terms of efficiency, cost and quality of the final processing that open up new production possibilities. This is why more and more companies have chosen a laser machine for the micro-drilling of wood panels intended for furnishing environments such as theatres, cinemas and public or domestic premises. But what exactly are the advantages of laser in microperforation?

How CO2 laser microperforation works

CO2 laser microperforation uses a high precision laser beam to create extremely small and even holes on the surface of the material. This process is based on a non-contact technology, where the laser beam vaporizes a minimum amount of material to form the desired hole.

Thanks to the digital control capability of the laser, it is possible to customize with extreme precision the density, diameter and arrangement of the holes, adapting them to the acoustic and aesthetic requirements specific to the panel. The most popular aspects of laser microperforation include:

• Absolute hole accuracy: each hole is created with precision beyond the millimetre, ensuring smooth edges, even holes and optimum sound absorption performance.
• Infinite design possibilities: thanks to the software control of the machining and the versatility of the high definition laser, you can achieve endless patterns and extremely accurate drawings.
• Combination of functionality and aesthetics: in addition to the possibility of creating graphic effects with a practically impalpable texture, the laser-made micro-holes guarantee better sound absorption because they are more precise and homogeneous.

All the advantages of laser microperforation on acoustic panels

The innovation of CO2 laser for the micro-drilling of panels has allowed to improve both the production efficiency and the quality of the finished product. For companies that invest in a laser machine this means taking advantage of a number of benefits, such as:

1. Cost and time savings:

CO2 laser significantly reduces operating costs compared to traditional technologies such as punching machines. Laser microperforation allows:

• Eliminate the setup time normally required to set up or replace mechanical tools;
• Save on consumable tools, as there are no punches or molds to replace, resulting in lower maintenance and consumables costs.

2. Superior acoustic performance

As we have seen, laser microperforation allows to obtain panels with an improved sound absorption, thanks to:

• Smaller, denser holes with diameters of less than 0,5 mm, which allow for higher drilling density, improving acoustic properties and reducing noise more effectively;
• Uniform hole distribution, which optimises sound absorption.

3. Less environmental impact

The laser microperforation process is more sustainable than traditional punching. Using laser in processing:

• Waste is reduced, thanks to the precision of the laser beam which avoids waste of material;
• Waste disposal is reduced, as unlike punching, which produces residues or chips, the laser vaporizes the material, eliminating almost completely the need for disposal.

4. Reduced maintenance

CO2 laser machines require less maintenance than punching machines. In fact, since there is no mechanical contact, there are no tools that wear out. Periodic maintenance is therefore simpler and faster, reducing machine downtime and improving overall operation.

5. Customisation and flexibility

With the CO2 laser, it is possible to respond quickly to specific market demands, as it allows:

• Rapid prototyping, thanks to the possibility of changing the design of the holes in real time without additional costs.
• Adaptability to materials, as the laser can punch through materials of different hardness and thickness without requiring hardware modifications.
