What is Metal Laser Engraving?

Metal laser engraving is a technique that uses a high-powered laser beam to etch or mark a design onto a metal surface. The laser beam vaporizes or melts the metal, creating a permanent mark that is precise and of high quality. This method of engraving ensures durability and longevity, making it ideal for various applications.

How does Metal Laser Engraving Work?

The process of metal laser engraving starts with a laser engraving machine. This machine consists of a laser source, a lens system, and a computer-controlled system that guides the laser beam. The laser beam is focused to a pinpoint, which allows for incredibly precise engraving.

When the laser beam comes into contact with the metal surface, the high heat from the beam vaporizes or melts the metal at the point of contact. This creates a mark that can be deep or shallow, depending on the intensity and duration of the laser pulse. This process can be repeated multiple times to create intricate designs or patterns.
