Which Industries Use Laser Etching & Engraving?

Pulsed fiber lasers have a very low power consumption.

Fiber and CO2 laser systems require no consumables.

Laser etching and laser engraving machines require very low maintenance.

Laser marking has a high resolution a lot of information can be packed in a very small area (especially if you’re using data matrix codes).

Laser direct part marking encodes information that cannot be detached from the product throughout its useful life.

How Etching and Engraving Solve Those Issues In addition, you’ve probably had to deal with inconsistent results due to an unreliable marking system. If you’ve tracked parts with dot peening, inkjet printing or printed labels in the past, you know that these marking technologies come with important maintenance and consumable costs. Why Do You Need Laser Etching & Laser Engraving? In the following video, black marks are created through deep laser engraving and the white background through etching.

You need to integrate laser marking before abrasive treatments, including shotblasting and sandblasting.

The engraving depth can reach up to 500 microns. Instead of creating a micro-surface that is raised above the material, laser engraving digs into the material. This is done by sending a highly localized laser pulse onto your part. Through the engraving method, the laser vaporizes a thin layer of the material to create a tracking code. You will also see the high contrast that results from etching. Watch the following video to see how fast our fiber lasers can etch the material’s surface.

You need to integrate laser marking before non-abrasive treatments, including powder coating, e-coating, and heat treating.

You want a cost-effective laser that requires less laser power.

Your part is made of any metal, except stainless steel.

Etching is faster than engraving because it requires less energy from the laser beam. Laser etching creates black and white marks and is the most efficient process to permanently mark most types of materials. By doing so, the laser etched surface expands and creates a texture. When etching is performed, the laser heats and distorts the micro surface of the material. Let’s dive into each process to see which is best for which application. Both processes use high heat to create permanent markings on metal surfaces.īoth processes are heavily used for part traceability. The main difference between laser etching and laser engraving is that etching melts the micro surface to create raised marks, whereas engraving removes material to create deep marks.

And more importantly, which one is right for you. If you are relatively new to laser technology, you are probably wondering what’s the difference between laser engraving and laser etching.
