How Is Laser Marking Different from Traditional Engraving?
Laser marking is fundamentally different from traditional engraving in a number of ways. To begin with, laser marking employs a concentrated beam of light to mark materials’ surfaces while the latter utilizes a tool to physically cut into the material. This distinction implies that laser marking is typically noncontact, reducing the wearing off of the marking equipment and also minimizing damage to the substrate. Besides this, it allows for higher precision and the creation of more complex designs. Moreover, it can deliver high speed and high contrast results when used on metals, plastics and ceramics among other materials. On the contrary, traditional engraving may be preferable for deeper cuts and offers a finished product that has tactility.
Understanding the Process of Laser Marking
Laser marking involves using a high-powered laser beam to change the surface properties of materials resulting in accurate and permanent marks. It starts with generating the laser beam which is then passed through several mirrors and lenses to concentrate its energy at a small area on the target material. The focused light interacts with the material’s surface leading to localized heating, chemical events or physical changes as may be applicable depending on the material and type of laser.
Several types of laser marking techniques exist including:
- Annealing: This method heats up metal without removing its surface hence resulting to alteration of color due to oxidation.
- Etching: This is where the material melts away and vaporizes thus creating depth.
- Engraving: An intense beam removes material leaving deep lasting marks.
- Ablation: Coatings or films are removed exposing underlying materials while not affecting the substrate.
Laser marking is highly valued for its speed, accuracy, and versatility. In many cases it can mark metals, plastics, ceramics, glass and other materials without requiring further finishing steps. Computer-aided design (CAD) software has made it possible for manufacturers to design complex parts that they can produce with consistently high quality even in large numbers.
Differences Between Laser Marking and Laser Engraving
Laser marking and laser engraving are different methods that people confuse quite often though the differences between them are precise.
Usually, laser marking alters the surface properties of a material without removing material. This leads to chemical or molecular changes due to contact of the laser beam with the material’s surface resulting in marks. The energy is low and thus it results into visible but less deep marks. Such consequences are normally needed for barcodes, serial numbers, etc., when durability and precision matters while depth is not important.
On the contrary, laser engraving entails removal of materials at its surface through vaporization thereby producing deeper and more enduring marks. Increased energy levels are used to cut into the object thus creating a tactile groove or indentation. Laser engraving is commonly employed in personalizing items like trophies, industrial components which must have marks resistant to wearing out.
Summarily speaking, there are two major differences between these two techniques: how deep they go and how visible their marks appear. While laser marking is all about changes within one layer by means of a laser beam, lasers engrave deeply into materials. The two techniques being highly accurate can be applied with versatility depending on what one wants to achieve from an application.
