Application industries of laser marking machines?
Apr 18, 2025
Laser marking machines are widely used in many industries due to their advantages such as high precision, permanent marking, contactless processing and environmental protection. The following are the main industries suitable for using laser marking machines and their application scenarios:
1. Electronics and semiconductor industry
Application scenarios: used for marking printed circuit boards (PCBs), integrated circuits, electronic components, especially the precision marking of ceramic circuit boards. Laser technology can replace traditional ink printing to solve the problem of high brittleness and difficult marking of ceramic materials.
Technical requirements: UV lasers and fiber lasers are often used for marking tiny QR codes and data matrices to meet the traceability requirements of electronic components.
2. Automobile and aerospace
Application scenarios: serial numbers and brand logos of automotive parts (such as engine parts and brake pads), and permanent marking of aerospace parts. Laser marking can withstand harsh environments such as high temperature and corrosion213.
3. Medical equipment and pharmaceuticals
Application scenarios: identification of medical devices (such as surgical tools and implants), batch numbers and anti-counterfeiting code markings on drug packaging. Laser marking meets the medical industry’s requirements for sterility and disinfection resistance.
4. Food and packaging
Application scenarios: production date and expiration date marking of food packaging, as well as anti-counterfeiting labels for plastic and glass containers. CO₂ laser is suitable for rapid marking of non-metallic materials.
Environmental advantages: no ink is required, chemical pollution is reduced, and it meets food industry safety standards.
5. Jewelry and luxury goods
Application scenarios: fine engraving of precious metals (such as gold and platinum) and gemstones, and personalized customization of luxury brand logos. UV laser can achieve cold processing without heat damage and retain the texture of the material.
6. Industrial manufacturing and tools
Application scenarios: serial number marking of tools and molds, and deep engraving of metal parts. Fiber laser is suitable for permanent marking of materials such as stainless steel and aluminum alloy.
Efficiency requirements: the application of high-speed on-the-fly marking technology in industrial assembly lines to improve production efficiency.
7. Promotion and personalized customization
Application scenarios: lettering and pattern design of promotional gifts (such as mugs, key chains) and personalized products (mobile phone cases, trophies). CO₂ laser supports flexible processing of a variety of non-metallic materials. Business model: The demand for small-batch customization is growing, and portable
