What is the difference between laser marking and engraving?

Generally speaking, laser marking refers to placing readable information on the surface of a part with little or no penetration, whereas laser engraving refers to placing information on a part with obvious penetration below the surface. Laser marking discolors the surface of the material, while laser engraving removes a portion of the surface area as you mark. The main difference between laser engraving and engraving is the depth at which the laser penetrates the surface. Instead of creating a microsurface that rises above the material, laser engraving goes deep into the material.

The engraving depth can reach up to 500 microns. Laser marking is a manufacturing process that uses a focused beam of light to permanently alter the surface of the workpiece. Unlike laser engraving, it changes the surface without removing material. Produces durable, high-contrast marks that can be easily read or scanned.

The terms “laser marking”, “laser engraving” and “laser engraving” are often used interchangeably, but there is a difference. Laser marking refers to placing readable information on the surface of a part with little or no penetration. In contrast, laser engraving refers to placing information on a part with obvious penetration below the surface of the material. The same laser can perform any technique simply by changing the settings within the laser marking software.

Laser engraving creates marks on parts and products by melting their surface. The laser beam sends a large amount of energy to a small area to create a relief impression. The engraving and marking are very similar and can be used interchangeably. However, the term “laser marking” is more often associated with metals and engineering plastics, while “laser engraving” generally refers to other substrates such as wood, acrylic and plastic.

Laser engraving is basically the use of lasers to engrave an object. On the other hand, laser manufacturing is a fairly broad category that involves leaving marks on objects. It also involves a color change due to melting, ablation and foaming, charring, melting, and molecular alteration. Laser engraving techniques are a rather advantageous type of engraving, since it does not involve the use of drill bits or ink.

Therefore, it can be an excellent alternative to engraving, since it does not wear down the engraved surface. Laser engraving creates a cone-shaped indentation in the surface of the material. Laser engraving produces a high contrast mark on the surface of the material by vaporizing only the surface layer of the material. Laser marking creates high-contrast marks without altering the material itself by a method called discoloration.

Laser engraving also uses high temperatures to melt the surface of the material, producing a slightly raised engraving pattern of your choice. My husband's company is launching a new product and they are trying to decide if they should do a laser marking or engraving on it. If you laser engrave a design on some jewelry, it will quickly fade if the piece is touched frequently because the depth is only 0.001 inches. The difference between annealing and etching is that annealing is a chemical reaction and that it does not melt the surface of the material.

The cone-shaped slits created in the laser engraving process can be deepened by passing the laser over the same areas several times. Laser engraving is not recommended for safety-critical parts, as the engraving process may damage or structurally compromise the engraved part. That's just one of the reasons why it's important to choose a laser marking methodology that fits your intended purpose. Between dot blasting, inkjet printing, laser marking and printed labels, the right solution is not always obvious.

Over the years, the laser has become one of the most powerful manufacturing tools a company can use. TYKMA Electrox specializes in reliable, customer-focused laser marking systems for engraving a variety of materials. Learning how laser engraving differs from laser engraving is really interesting. For example, manufacturing on micrometer, vernier-caliper or other measuring instruments is carried out by permanent laser marking.

While there are other ways to mark materials, they don't give you the quality or environmentally friendly marks that come with laser marking, engraving and engraving. In the manufacturing industry, for example, lasers are used in a variety of everyday tasks, such as welding, cutting, cleaning, measuring, drilling and detection, as well as in marking, engraving and engraving. TYKMA Electrox offers precise laser marking, engraving and engraving systems for almost any industry and application you can think of. A low-power laser generates just enough heat to oxidize the material beneath the surface and turn it black, creating distinctive, high-contrast marks that are easy to identify.
