![]() ![]() It’s typically used to laser engrave serial numbers and logos, among other things.It’s great for parts expected to experience high wear.This is the fastest way to mark with a laser.The maximum engraving depth is 0.020″ in metals but can go as deep as 0.125″ in materials such as graphite.Laser engraving is not ideal for marking safety critical parts.This is the most common option for people who want something personalized or customized.There are three types of laser engraving: etching, deep laser engraving, and laser ablation (the difference between the three is what the surface is and how much you remove).To form deeper marks with the laser engraving system, repeat with several passesĪlthough laser engraving is a subsection of laser marking, it still differs in many ways:.This creates a cavity in the surface that is noticeable to the eye and touch.It’s a quick process, as the material is vaporized with each pulse.High heat is created during the laser engraving process, which essentially causes the material to vaporize.Laser engraving is a process where the laser beam physically removes the surface of the material to expose a cavity that reveals an image at eye level. Laser marking is ideal for bar codes, UID codes, QR codes, logos and other identification needs.It’s popular in the medical device industry for stainless steel and titanium parts, but can be performed on other materials as well.There are four common types of laser marking: annealing, carbon migration, foaming and coloration.It is also referred to as laser coloration or laser dark marking, as well as charring for plastic materials and annealing for metals.It is less common and not all places offer these services.Laser marking differs from laser engraving and laser etching in a number of ways, including the following: All of this is done while leaving the surface intact.It applies low temperatures to metal to anneal the surface.Laser heats the material, causing oxidation under the surface and turning the material black.It is achieved by moving a low-powered beam slowly across the material using a method called discoloration, which creates high-contrast marks without disrupting the material.Some of the features of the laser marking process include the following: Laser marking is what happens when the beam interacts with the surface of a material, slightly altering its properties or appearance. ![]() Request Information The Laser Marking Process TYKMA fiber laser systems are ideal for all types of laser marking, etching and engraving in a variety of materials and substrates. Laser Marking, Etching and Engraving Demonstration Each type of process has its own applications and attributes that make it ideal for different jobs. The Main Differences Between Laser Marking, Etching and EngravingĪlthough these terms are often used interchangeably, there are differences between laser marking, laser etching, and laser engraving. ![]() Throughout this post, we will give you an overview of each of the processes and their applications to help you better determine which is right for your application needs. The major difference between laser etching and laser engraving is the depth to which the laser penetrates the surface. Laser marking discolors the surface of the material, while laser etching and engraving actually removes a portion of the surface area as it marks. The differences between laser marking, laser engraving, and laser etching largely have to do with what each process does to the marking surface, including how deep the laser goes and how it changes the overall appearance. ![]() While the three techniques may seem similar, there are actually quite a few differences between them. Thanks to industrial and government regulations regarding clearly legible product and part identification, the processes of laser marking, laser etching, and laser engraving are increasing in popularity.Īll three of these laser services provide permanent laser marking solutions, fulfilling regulations and adding distinction to your products and parts. ![]()
