Portable Laser Marking System features-Suntop

This compact, portable UV laser marking machine features a 355nm "cold" UV laser source and an integrated air-cooled design. Its small, lightweight build allows for flexible placement and mobility, eliminating the need for complex water-cooling systems. The machine produces a fine laser spot with a minimal heat-affected zone, ensuring no burning or damage to heat-sensitive materials such as plastics, glass, and anodized aluminum; the resulting markings—whether text, patterns, or logos—are crisp, durable, and resistant to wear.


Suitable for a wide range of precision processing applications, the device can mark electronic components, PCBs, cosmetic packaging, silicone accessories, optical lenses, and small hardware parts. It supports the marking of serial numbers, QR codes, scales, logos, and more. With simple operation and a stable control system, the machine is ready for immediate use, meeting the needs of both batch processing in workshops and on-site marking in the field.


The unit features a lightweight, portable structure with a small footprint, reducing transport and handling costs. Available directly from the factory in 3W and 5W power options—with free sample testing provided—it caters to the high-precision marking requirements of small processing plants, jewelry workshops, and electronics manufacturers.
