      How laser marking is done

      Application of laser marking and engraving on different surfaces can vary a bit, depending on the equipment and specifications, as well as the type of material.

      The general procedure is based on the following steps:

      1) Prepare the equipment

      The first thing you must do is conduct the checklist to guarantee that the laser equipment is in optimum operational condition, verifying that all settings are properly configured. You must also verify that the equipment’s control software is installed and updated.

      2) Prepare the material

      You must clean the material’s surface to remove all leftover dirt or other contaminants that could affect the laser mark’s result. You must also verify that the material is properly held in the device.

      3) Mark design

      With the aid of specific laser design software, you can create or import the design you want to mark on the material surface. You will need to adjust the size, position, and other parameters.

      4) Laser settings

      At this point, you must adjust laser parameters, such as marking speed and beam intensity and frequency, depending on the material type and desired depth.

      5) Focus configuration

      In regard to this point, you must adjust the distance between the laser head and the material’s surface to guarantee the necessary precision in the focus. Laser equipment offers a series of tools and aids that you can use to obtain a perfect focus.

      6) Start the laser mark

      Now with all necessary aspects properly configured, you can begin the laser marking process, using the command through the software control.

      After this, the high-energy beam of light emits, marking on the material’s surface based on the previously established settings and design.

      7) Verification and finish

      When you finish the laser marking and engraving design on the material, you must verify that the result is the one you want in terms of quality, depth, and precision.

      Laser marking and engraving FAQs

      COUTH wants to help you to get all the information you need before purchasing our laser marking and engraving devices. As such, here are FAQs about this marking method.

      1. What is laser marking?

      This is a technique or procedure used to mark and label different materials or products with a laser beam. The laser beam takes light action on the surface of the material, removing a small fraction of it and leaving a permanent mark.

      2. What is a laser marker machine?

      This is a device that uses fibre laser technology for the permanent mark or engraving on the surface of different materials.

      These devices have a system that uses mirrors, which make it possible to guide the laser with the utmost precision over the surface to mark.

      3. Which materials can you laser mark?

      Laser marking and engraving can be applied to different materials in different industries, used in sectors such as automobile, aeronautics, iron and steel, jewellery, food, etc., for different applications like item customisation and more.

      These materials include:

      • Metals such as aluminium, brass, gold, silver, platinum, titanium, stainless steel, bronze, copper, and more.
      • Plastics, such as plastics with additives for laser, polycarbonate,  ABS, PVC, polyamide, PMMA.
      • Glass.

      4. Are there different laser marking techniques? What are they?

      Yes, there are different types of laser marking techniques. They depend on the material and the type of finish you seek to obtain, as well as the device’s power.

      The most well-known laser marking techniques are:

      1. Annealing:
      2. This technique is an exclusive kind of laser mark for the metal market. It consists of taking advantage of the oxidation process caused by the laser underneath the surface of the material you are working on, changing the colour instead of going black with the heat created by the laser beam.
      3. The colour you obtain depends on the kind of metal and power level you use.
      4. Laser engraving:
      5. This procedure melts the surface of the material you are working on. It evaporates with the laser, thus producing a permanent engraving in the depression made.
      6. Elimination:
      7. This laser marking technique eliminates the top layers of the material you are working on, which creates a contrast with different colour tones between the bottom and top layers. This can be applied to materials like painted metals, anodised aluminium, films, and laminates.
      8. Decolouring:
      9. Decolouring is a procedure based on a chemical reaction with the material you are working on, as a result of the heat generated by the laser. This creates changes in the colour tones depending on the material.
      10. Foaming:
      11. With this procedure, the material is melted by the laser beam, which causes bubbles of gas on the surface that reflect the light. It is usually used with dark plastics.

      5. What power levels do laser marking machines have?

      Laser marking machines provide a wide power range:

      • 20W
      • 30W
      • 50W
      • 60W
      • 100W
      • 200W

      Depending on the material and the work you are doing, you can select the right power.

      6. Can laser marking and engraving damage the material?

      The material used for a laser marking and engraving process is called substrate. It should be noted that it does not suffer damage with this kind of procedure.

      What you should remember is that laser marking can slightly alter the surface of the substrate, leaving a permanent mark, with no need to apply adhesives, dyes, or any other related method.

      7. How do you maintain laser marking machines?

      Laser marking machines do not require complex maintenance. This is one of their advantages, since it leads to significant cost savings on expenses related to this kind of equipment.

      Additionally, COUTH laser marking and engraving devices are high quality and one of their main features is high performance, with great resistance and a long life cycle.

      Maintenance is based on protecting the devices’ optics, which must be revised before, during, and after laser marking. To this end, you need to adequately protect and clean the lenses with optical solvents when not in use, following basic recommendations.
