A UV laser marking machine is a device that can produce an ultraviolet laser beam to engrave the surface of the materials. UV Laser marker can also be called UV Laser engraver. We all are familiar with the diode. This ultraviolet ray comes from the UV laser diode based on Gallium Nitride – GaN. It emits the near UV laser wavelength. Ultraviolet laser marking has properties of short wavelengths and small spots. A 355nm UV laser engraving machine adopts 355 nm lasers. In this case, It usually has the output power of 3W, 5W, 8W, and 10W. The UV marking area can be 100 x 100 mm or 150 x 150 mm. The machine typically needs 110v/220v of power supply. The repeating pulse rate usually is from 1 kHz to 30 kHz.

It is suitable for non-metallic materials such as plastics, silicone, glass, ceramics, acrylic, rubber, polymer materials, etc.; it is suitable for ultra-fine marking.

Yes, it can mark dark materials, such as black plastic. These materials have a high absorption rate for UV light, so the marking effect is usually clear and has high contrast.
