Different methods to use Laser Marking

1. Different methods to use Laser Marking Laser marking machines and embossing tools allow us to achieve flawless results on practically all types of metals, ranging from staining, material extraction or engraving in 2 or 3 dimensions. Depending on the results you want to achieve, it will be more effective to use one method or another, which we will see below. Surface laser engraving: This type of marking occurs when the heat emitted by the laser does not reach the melting point and therefore only a color change occurs on the working area. This creates a very effective contrast that allows us to mark the metallic material without penetrating it or changing any of its properties. This type of Control panel engraved is practically indestructible to corrosion and is used above all in titanium, stainless steels and carbides, being highly appreciated in the medical and aeronautical sectors. Marked by layer removal: Through this technique, we are going to extract a layer of the metal cladding and expose its lower part, so that a color difference appears that allows us a fast, effective, exact and burr-free contrast. Engraving by steel marking stamps removal does not damage metal components and is used especially on painted surfaces and materials such as anodized aluminum. It is perhaps the fastest method of all that we are going to see today, an essential factor in ensuring that we respect delivery times and that it adapts perfectly to signaling plates and other similar elements. Laser engraved: When the melting temperature is reached, we can melt or evaporate the metal depending on the type it is. Laser engraving machines can be configured to select the appropriate power and thus make grooves more or less deep and with more or less contrast. This marking is carried out directly on the piece and is permanent, very resistant to wear and tear over time and to that produced by transport and storage. It is mainly used to identify high-cadence elements, engrave decorative motifs and personalize parts in the automotive industry and other sectors with similar requirements. Deep laser engraving: The power and flexibility of stencil marking equipment allow us to engrave metal parts in 2.5D and 3D. We can perform complex operations such as marking molds and tools in sectors that require enormous precision, such as watchmaking. These teams pre-calculate the route they have to make on the surface and are capable of making even the smallest of details without the piece suffering any type of damage or deforming.
