Laser Marking, Etching and Engraving – the Processes
Laser marking, etching and engraving processes all use the highly concentrated energy from a parallel beam of light, focused to an intense spot. This spot is guided by control software over the area to be marked, etched or engraved. This provides the ability to create a huge variety of durable images on a wide range of materials – very much like writing with a pen on paper (only far more accurate and repeatable!)
The legibility of marks made by lasers is achieved by creating a contrast between the mark and the base material. This contrast results from one of several processes, including engraving, chemical reaction, annealing and ablation.
Laser Marking, Etching and Engraving – the Materials
Suitable materials for marking, etching or engraving with lasers include most metals and plastics, glass, wood, ceramics and even foodstuffs. Electrox laser systems employ a range of fiber, CO2 and UV based laser technologies that can readily mark, etch or engrave a huge range of materials and products. This list of materials is not set in stone so please contact LMI to see if we can offer a solution for your application.
Laser Marking / Laser Engraving Machine / Laser Etching - different definitions
What is the difference between laser marking, laser engraving and laser etching?
In laser processing there are serveral processes that decribes how concentrated laser light affect a material. For the uninitiated it can be confusing and hard to distinguish the marking concepts.
The processes are:
Laser engraving that involves vaporizing the surface of materials to produce a high quality inscribed mark.
Laser annealing, synonymous to laser etching. For most bright steels, a surface color change can be achieved by annealing using laser marking equipment. Enabled by precision-controlling the heat output, the laser marker is able to produce a highly legible mark in varying color on the surface being marked, without employing additives.
Chemical reaction. When exposed to laser marking radiation, most plastics react by developing a mark. The type of mark achieved depends on the type of reaction initiated by the laser – typically melting, foaming or bleaching. That reaction depends on the composition and color of the base material. To enhance/modify the color change, additives may be used.
Ablation involves creating marks on anodised, plated or painted products by using a laser marking system to remove the top layer, which exposes the base material in a contrasting colour. By removing an opaque layer from a substrate the creation of graphics for back-lit, day/night products and light show projection devices is enabled.
