Exploring the Craftsmanship of Metal Logo Plaques: Laser Engraving

Writer：admin Time：2025-02-28 19:56 Browse：℃

Laser engraving of metal logo plaques is a rapidly developing new process in recent years, widely welcomed for its high precision and non-contact characteristics. This technique utilizes a high-energy laser beam to etch the metal surface, creating permanent markings.

The core equipment for laser engraving metal plaques is the laser generator. Commonly used types include fiber lasers and CO2 lasers, with the former being more suitable for metallic materials. The laser beam is precisely controlled in position by a galvanometer system, generating high temperatures on the metal surface to vaporize or discolor the material, forming patterns. The depth and color of the engraving can be controlled by adjusting the laser power and speed.

The advantage of laser engraving metal plaques lies in its extremely high precision. It can engrave patterns with line widths of just 0.01mm, with clear and sharp edges. Additionally, as a non-contact processing method, it does not exert mechanical stress on the material, making it particularly suitable for processing thin sheet materials. This technique can achieve various effects such as black-and-white contrast and varying depths of engraving.

Another advantage of laser engraving metal plaques is its flexibility. It allows for quick changes in engraving patterns, making it suitable for small-batch customized production. Furthermore, when combined with a computer control system, it can achieve precise engraving of complex patterns. This process is particularly suitable for producing high-end plaques such as precision instrument panels and commemorative plates.

Laser engraving of metal plaques has a wide range of applications and can be used on various metallic materials including stainless steel, aluminum alloy, and copper. Different materials have different laser absorption rates, requiring adjustments to laser parameters for optimal results. Fiber lasers are suitable for stainless steel and aluminum alloy, while high-power CO2 lasers are suitable for copper materials.

With the development of laser technology, the efficiency and precision of laser engraving continue to improve. The emergence of new ultrafast lasers has made engraving quality even more refined. Ultrafast lasers can release high energy in an extremely short time, reducing the heat-affected zone and improving engraving precision. In the future, laser engraving will play an even greater role in the field of personalized custom plaque production.
