Differences Between Laser Marking and Engraving

  1. Principles of Laser Marking and Engraving

Laser marking is a technique used to mark items by utilizing a high-energy laser beam (CO2 laser, fiber laser, etc.) to create a high-temperature oxidation reaction on the surface of an object, forming a mark. Engraving, on the other hand, involves using mechanical tools or chemical etchants to carve into the surface of an item. In principle, laser marking is a non-contact marking method that does not damage the item, while engraving requires contact with the item, which can easily cause scratches and damage.  

  1. Application Scenarios of Laser Marking and Engraving

Laser marking is typically used in situations requiring high-precision marking, such as electronic products, instruments, medical devices, and can mark various materials including metals, plastics, ceramics, paper, and glass. Engraving is more commonly used in arts and crafts, jewelry, watches, and other fields, achieving aesthetically pleasing patterns and text through mechanical carving or chemical etching.

  1. Summary

Although both laser marking and engraving are marking techniques, due to differences in their principles and application scenarios, they have different characteristics, advantages, and disadvantages in practical applications. The choice of which marking method to use should be based on the actual needs of the material, size, marking position, requirements, font size, and other practical needs of the item to be marked.
