Microperforation: The Invisible Technique for Adding Functionality

Microscopic Holes with Great Possibilities

Laser microperforation allows us to create holes on a micrometric scale in materials. These holes can modify the properties of the material, such as permeability to liquids, gases, light, and sound.

We believe that this technology has great potential for applications in various materials, including metals, films, plastics, and textiles. Therefore, we have developed a wide range of laser microperforations to meet the needs of our clients

Laser micro-perforation innovation for all needs

Based on our knowledge and experience, we have developed a wide range of laser microperforations for different applications, taking into account the starting material and the function it needs to perform.

Our goal is the industrialization of this laser technology, so we constantly work to enhance our processes and optimize our results.

This is the width of the perforation mouth, i.e., the distance between its edges.

By this we mean the length that separates the centre of one hole from the centre of the next.

We can distribute them in different ways; depending on the process, they can be linear, intersecting, etc

Our methodology in micro-drilling

To transform a microperforation idea into industrialization, we follow a process of research, development, and manufacturing.

1

We define the diameter and spacing of the micro-perforations required for the application. These two aspects are key in this type of project.

2

We select, based on the material, the type of laser, power, and necessary optics. We have different types of lasers that allow us to choose the most suitable for each case (UV, IR, CO2, etc.)

3

Once the type of laser is selected, we optimize the laser parameters to achieve the best result for the application. Among the most important parameters are power, pulse, frequency, and spacing.

4

Subsequently, we manufacture the final prototypes, which will be used to validate the idea through functionality and aging tests.

5

In our characterization laboratory, we ensure to check the quality of the microperforations and conduct the necessary tests for validation.

6

Once we verify that the prototypes meet the established requirements, we take care of installing and integrating the laser equipment into the production process.

Our laboratory equipment

Lasers are devices that produce a concentrated and organized beam of light. In our laboratory, we have three types of lasers that are perfect for a variety of applications.

This is the most versatile of our machines, with variable spot diameters from 10 to 100 microns.

We can achieve the highest quality thanks to their emission of ultra-short pulses that prevent heat propagation.

We use this laser in situations where we want to provide a heat treatment to the material.

Some applications of micro-perforation

Laser microperforation opens up a new world of possibilities with great potential for the development of new applications in various materials, including metals, films, plastics, and textiles.

We can create filters with small hole diameters, high efficiency, large density, and precision.

This technology has great potential for applications in many sectors as it allows us to selectively control the passage of fluids, gases, light, or sound.

Through laser microperforation, we can create tiny holes in materials, increasing the contact area of the catalyst with the reactants. This, in turn, allows us to improve the performance of chemical reactions.

With this technology, we can modify its properties. In the case of films, it allows us to create pores that allow the passage of gases while blocking liquids.

With laser microperforation, we can create plastic packaging that releases a predetermined amount of liquid automatically at regular intervals. The size and quantity of holes determine the amount of liquid released.

We can create holes so small that they are almost invisible. These holes allow the passage of sound, which can be used to create products with a more attractive and functional design.

Creating these imperceptible holes with certain diameters allows light to pass through the material. This means we can make opaque surfaces transparent or create light patterns in materials that are not translucent.
