Working Principle of UV Laser Marking Machine
UV (ultraviolet) laser marking machine realizes non-contact precision processing by emitting high-energy UV laser beams (usually with a wavelength of 355nm). After the laser beam is expanded, scanned and focused by the optical system, it acts on the surface of the material with micron-level precision, and removes the surface material through photochemical reactions (such as molecular bond breaking) or thermal effects (such as material evaporation/oxidation), thereby forming a permanent, high-precision mark. UV laser marking has the characteristics of short wavelength and high energy density, which can realize micron-level fine processing and is suitable for scenes with extremely high precision requirements.
Advantages of NITRATEK Ultraviolet Laser Marking Machine
UV laser marker has become the core equipment in the field of industrial manufacturing due to its high precision, non-contact processing and wide material adaptability. Its laser wavelength is 355nm (deep ultraviolet band), and the minimum line width can reach 0.01mm, which can realize micron-level fine etching to meet the needs of precision scenes such as electronic components and medical devices. The equipment uses photochemical reaction or thermal effect to remove the surface of the material, avoiding deformation or damage caused by traditional thermal processing. It is especially suitable for fragile or heat-sensitive materials such as plastics, glass, ceramics, and metals. At the same time, UV laser marking systems do not require consumables (such as inks), have no pollution emissions, and meet environmental protection requirements. The intelligent air cooling system, water cooling system and precision optical design ensure long-term stable operation, and the modular structure (such as Flying mode, desktop models) supports flexible configuration, adapting to small-batch laboratory research and development to high-speed production line mass production. Whether it is 3W/5W/10W power selection or 70*70mm to 300*300mm marking area, it reflects its significant advantages in efficiency, accuracy and cost control.
