Ablation foils

Laser foils are an interesting alternative for materials that are not directly (or only poorly) markable. The foils, specially developed for laser marking, consist of several layers: 

  • Carrier material
  • Foil with adhesive layer
  • Contrasting colour layer
  • Top-coat layer

The laser beam removes the top-coat layer on the foil, exposing the contrasting colour layer underneath. In a second step, the marking laser system can cut through the entire foil, thus enabling any 2D representable form to be displayed as a label.  Once the process is completed, the ready-to-use label can readily be removed from the carrier material.

The advantage of label marking is the flexible and wide range of applications, which is practically independent of the material used. The problems associated with conventional label marking, such as colour smudging and text fading, do not occur with laser labels. The foils, originally developed for the automobile and aerospace industries, are characterised by a high bonding strength as well as resistance to strong heat and liquids (oils etc.). There are types of label available that after bonding are impossible to remove without being destroyed in the process. Such labels provide a high degree of protection against warranty fraud.

Suitable systems

BusinessCO2

Enables fast and convenient marking on ablation foils. The BusinessCO2 series is also suitable for machining plastics, glass and organic materials.

BusinessDiode

The BusinessDiode series systems are suitable for medium to large batch sizes. Time-critical applications also represent no problem for these systems. They are also suited for machining metals, plastics and ceramics.

BusinessFibre

These lasers are particularly suited for time-critical processes. The primary application of these systems is in the fast machining of metals. Extremely high power is available for particularly time-critical applications. A variable pulse shape enables optimal flexibility in metal machining.

EconomyDiode

The EconomyDiode series systems are particularly suitable for small and medium batch sizes. They are also suited for machining metals, plastics and ceramics.

EconomyFibre

These lasers are particularly suited for time-critical processes. The primary application of these affordable marking systems with fixed pulse width is in metal machining.

Cover foils

As with ablation foils, cover foils with changing colours are used with materials that are not (or only poorly) markable. The significant difference between the two types of foils is that cover foils are coated with laminate layers that are transparent for the laser. The marking is produced beneath the laminate layer and can be made equally rich in contrast as with ablation foils. The laminate layer prevents gases and dusts escaping during the marking process.

The advantage of label marking is the flexible and wide range of applications, which is practically independent of the material used. The problems associated with conventional label marking, such as colour smudging and text fading, do not occur with laser labels. The foils, originally developed for the automobile and aerospace industries, are characterised by a high bonding strength as well as resistance to strong heat and liquids (oils etc.). There are types of label available that after bonding are impossible to remove without being destroyed in the process. Such labels provide a high degree of protection against warranty fraud.

The correct laser technology for the user is basically oriented to the machining time desired. The laser technology best suited for your application can be determined in one of the ACI laboratories by a free-of-charge test.
