"Engraving" material ablation

The laser beam ablates the material by means of vapourisation or melt ejection. In doing so, a noticeable indentation is created. Depending on the property of the material as well as the laser setting, it is possible to realise different depths (from fine surface engraving to depth engraving) and operating speeds. In comparison to, say, HSS, aluminium can be quickly machined – even with low power classes. By using a stronger laser, it is possible to further reduce the machining time.

Advantages of material ablation: Material ablation provides an abrasion-resistant marking able to withstand mechanical stresses for a long time. In addition, this method is not sensitive to heat influences or liquids such as water and oils.

Typical materials: Stainless steel, HSS, carbide, cast steel, aluminium, copper, brass, titanium, gold, silver, bronze, ...

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

Coating ablation

Ablation can also be perceived as a form of engraving. Here too the laser vapourises the surface of the workpiece. In contrast to engraving, not the primary material is affected but rather the coating on its surface. A typical practical example is the marking of anodised aluminium. The laser removes the eloxal coating, thereby exposing the layer of aluminium underneath. By clever choice of the anodising colour, it is possible to realise very beautiful and high-contrast markings.

Advantages of ablation marking on metals: Ablation provides an abrasion-resistant marking able to withstand mechanical stresses for a long time. In addition, this method is not sensitive to heat influences or liquids such as water and oils.

Typical coatings (selection): burnished, nickel coated, coppered, chromated, anodised and lacquered materials
