Portable UV Laser Marking Machine 3W 5W 10W For High Precision Marking


Ultraviolet laser marking machine uses 355nm UV laser as the light source. The machine uses third-order intracavity frequency doubling technology. Small size, can greatly reduce the mechanical deformation of the material and has little influence on the processing heat, it is mainly used for superfine marking, engraving, cutting.

Portable UV Tabletop Laser Marking Machine

Product Description

The UV desktop air-cooled laser has a wavelength of 355nm UV laser, and the average output power is 1, 3, 5, 10W optional.
The laser repetition frequency is adjustable in the range of 20KHz-200KHz,  One-piece design, integrated drive circuit board inside,
The laser output can be obtained by connecting a 12V stabilized power supply externally. Without adjusting frame manufacturing process, the laser has stable mechanical performance and can run stably for a long time.

1.What is the processed material? ( stainless steel, aluminum, wood, plastic etc....)

A: Fiber laser marking machine is for marking metal part and CO2 laser marking machine is for marking non-metal part. UV laser is for brittle and non-metal materials.

2.Effective marking size?

A:110*110mm, 200*200mm, 300*300mm or customized size.

3.How to mark on cylindrical or round surface?

A: Standard models can mark on flat surface, if curved surface marking is needed, you need pay extra for a rotary fixture.

4.What is your marking depth?

A: All laser marking depth is less than 1mm, but if you keep marking and marking repeatedly, it will be deeper.
