Laser Marking: The Modern Standard for Permanent Marks

Laser marking has become the industry standard for many manufacturers seeking fast, precise, and non-contact identification solutions. This method uses high-powered lasers—such as fiber lasers, CO₂ lasers, and UV lasers—to create a variety of marks, including:

• Annealing: Alters the color of the metal surface without removing material—ideal for medical devices, surgical instruments, and stainless steel parts where corrosion resistance must be preserved.
• Etching: Uses laser energy to vaporize the surface, creating high-contrast marks on metals, plastics, ceramics, and more.
• Engraving: Removes more material to create deep, lasting marks that withstand wear, abrasion, or chemical exposure.
• Foaming: Generates raised marks, particularly on plastics, by causing localized melting and bubbling.
• Color Change: Alters the chemical structure of the material to produce visually distinct marks, especially on polymers.

Laser marking systems are favored in industries such as aerospace, automotive, medical device manufacturing, electronics, and defense due to their versatility, speed, and ability to meet strict quality standards. Advanced laser marking machines can be programmed for fully automated, high-throughput production, or operated as standalone workstations for prototyping and custom jobs.
