Driven by the wave of digital manufacturing and personalized consumption, logo laser marking is becoming a revolutionary technology in the field of industrial identification. It not only solves the efficiency and accuracy problems of traditional identification methods, but also provides new possibilities for the production of brand logos through the precise control of high-energy laser beams. From smartphones to medical devices, from luxury goods to environmentally friendly packaging, from automotive to keys, laser marking technology and logo laser marking machines are redefining the way brands and products are connected with the characteristics of "non-contact, high-precision, and permanent".

I. Technical principle of laser marking logo

The core of logo laser marking is to use high-energy-density laser beam to locally irradiate the surface of the material, and achieve permanent marking through the following two methods:

Vaporization etching: The laser energy instantly evaporates the surface of the material to form a logo pattern or text of varying depths.

Chemical discoloration: Laser irradiation triggers a chemical reaction on the surface of the material, changing the color or gloss (such as metal oxidation, plastic carbonization), thereby achieving logo marking.

For example, ultraviolet laser (354.7nm) is widely used in the fine processing of heat-sensitive materials such as leather and plastic due to its "cold processing" characteristics; while fiber laser (1064nm) has become the first choice for metal marking with high stability and low maintenance cost. This non-contact processing method not only avoids the stress damage of traditional mechanical engraving, but also eliminates the risk of contamination of ink jet coding. Laser marking is the best solution for modern logo identification.

II. Technical advantages of using laser marking machine to mark logo

Ultra-high precision: The minimum line width of laser marking can reach 0.03mm (such as ultraviolet laser), which far exceeds the accuracy limit of traditional etching or screen printing. In the field of consumer electronics, the cutting error of the logo on the back cover of mobile phones and the A side of laptops can be controlled within ±0.01mm to ensure the perfect presentation of the brand logo.

Strong material adaptability: The laser marking machine can help you achieve perfect logo marking on a variety of different metal materials, such as stainless steel, aluminum alloy, copper, etc. The logo cutting edge is smooth and burr-free, and no secondary polishing is required. For non-metallic materials, such as plastics, ceramics, glass, etc., ultraviolet laser marking technology can also achieve controllable depth and texture engraving on these various surfaces to meet personalized design needs.

Meet the marking needs of special scenarios: In the food and medical fields, the corrosion-resistant marking of medical equipment and the FDA compliance marking of food packaging can all be achieved through laser technology. Standardized brand identification can effectively improve production efficiency.

Environmentally friendly and cost-effective: With laser technology, you don't need to prepare chemical materials such as ink and ribbons to mark your logo, which can effectively reduce waste emissions by 80%. If you use chemical etching to mark your logo, you need to regularly replace the acid and filter element, and you need to pay a certain maintenance cost every year. With laser technology, the annual maintenance cost can be reduced by 60%, helping you save costs. In addition, through software control, you can easily adjust the logo image or text in real time to meet the needs of small-batch customized production.
