Uv Laser Marking Machine

Goldplin Laser's UV Laser Marking Machines operate at a short 355nm wavelength, making them the ideal solution for marking heat-sensitive materials that cannot withstand the thermal energy of conventional fiber or CO2 lasers. UV laser marking is commonly referred to as "cold marking" because the photochemical process produces minimal heat, eliminating any risk of burning, discoloration, or material deformation.

Our UV laser marking machines are available in 3W and 5W configurations and deliver ultra-fine marking with minimum line widths below 0.01mm — making them the preferred choice for applications requiring exceptional detail and precision on delicate surfaces.

Materials Suitable for UV Laser Marking

UV laser machines can mark a wide range of materials including ABS plastic, polycarbonate, nylon, PTFE, glass, ceramics, sapphire, silicon wafers, PCBs (printed circuit boards), flexible circuits, medical-grade polymers, pharmaceutical packaging, and coated metals. The 355nm wavelength is absorbed efficiently by most organic materials, producing high-contrast permanent marks without any surface damage.

Key Applications

UV laser marking is widely used in the electronics industry for marking PCBs, IC chips, connectors, and cables. Pharmaceutical manufacturers use UV laser machines for compliant marking of blister packs, ampoules, and vials. The automotive industry uses UV lasers for marking transparent plastic components and sensor housings. Medical device manufacturers rely on UV laser marking for surgical instruments, implantable devices, and diagnostic equipment where heat-free, permanent marking is a regulatory requirement.

Why Choose Goldplin UV Laser Machines

All Goldplin UV laser marking machines are built with imported DPSS UV laser sources, high-precision galvo scanners, and F-Theta focusing lenses for consistent beam quality across the entire marking field. The compact, air-cooled design requires no water chiller and minimal maintenance. Our machines come pre-configured with EzCad software and support all standard marking formats including text, serial numbers, barcodes, QR codes, Data Matrix codes, and vector graphics.
