Product Description

This SUNNA 355nm 3D 5W UV Laser Marking Machine For Glass Plastic Paper Cloth uses a 355nm UV laser source, the 355nm UV laser provides a small size spot and large depth of focus, by short wavelength laser marking interrupts the molecular chain of the material, which can greatly reduce the mechanical deformation and temperature deformation of the material, it is a cold light, mainly used for ultra-precision marking and engraving, especially suitable for food and pharmaceutical packaging materials, micro-hole.

Advantages of UV Laser Marking Machine

Long service life,degree of power instability less than 3%

Line marking can be realized

Laser source Modular design,could adapt long working time

Fiber laser marking frame,small size and compact

Supports continuous 24/hour workloads

Easy to use and maintenance free

Desktop UV laser marking machines are known for their high absorption rates, which enable them to mark various materials with minimal heat damage and excellent contrast, especially on plastic and organic materials.

How do Desktop UV Laser Marking machine system work?

Desktop uv laser marking machine have a much shorter wavelength than fiber laser type. Using “cold processing”, this process does not produce thermal deformation (heat damage) on the inner layers and nearby areas of the target area.

A UV laser’s wavelength is one-third of standard wavelength lasers, therefore often referred to as third-harmonic generation (THG) lasers. This wavelength is achieved by passing a standard wavelength laser at 1064 nm through a non-linear crystal, reducing it to 532 nm, this is then passed through another crystal, reducing its wavelength further, down to the working 355 nm.

In summary, UV lasers work a little differently to their CO2 or Fibre based siblings as they do not damage the materials surrounding surface, using a far lower power form of marking. This makes them the best of the bunch when it comes to “marking”, suitable for anything from fruit, to glass, diamond, silicone, plastic and precious metals. You really can mark almost anything with a UV laser!

UV Laser Marking Machine for Plastic Feature and Application

Desktop uv laser marking machine with high quality light beam, small focal point, ultra- fine marking.

Low energy consumption, environmentally friendly, no consumables.

Little affect area, no heat effect, without material burned problem.

Continuous operation for 24 hours meet the needs of industrialized mass production of online or offline.

High Marking Speed.With high repeat frequency of the pulse,power output steadily,energy surge of single pulse is lower than 1%,can achieve high speed marking,and control the depth and shape of the facula.

Easy Operating.Afford the specific marking software based on windows,which is real-time adjust the laser power and pulse frequency.You can edit what you need to mark directly by the specific marking software and the graphic software such as Auto CAD,CORELdraw of photoshop.

Delicate marking.High quality laser beam(near to the limit of diffration,exporting TEM00 fundamental transverse mode,M2 near to 1,expanding angle of laser beam is only 1/4 of the diode laser marker).Therefore it is very suitable for delicate marking.from quivering and resonance during long time work.
