Laser Marking Machine For Polycarbonate

Jun 13, 2021 Upload by OTLASER

Like other laser processing such as:such as laser welding, laser heat treatment, laser cutting and laser drilling etc,Laser marking is also a popular processing technology,which is replacement of traditional marking technology in many industry, especially in the application of plastic marking.There are commonly plastic materials used on the market like: ABS plastic (acrylonitrile-butadiene-styrene), PC (polycarbonate), PP plastic (polypropylene), PS plastic (polystyrene), PPS plastic (polystyrene) Sulfide), PP polypropylene, PVC (polyvinyl chloride), PE (polyethylene), acrylic (polymethyl methacrylate), etc. What type of laser marking machine can mark these plastic materials?

Affecting The Quality Of Laser Marking Plastics Factors


There are many factors that affect the quality of laser marking. When choosing a laser marking machine, you should consider the absorption rate of the material, the power density and the time of laser act on the material. Then What is a good laser marking polycarbonate ( PC) ?


There are common tree types of laser for marking polycarbonate(PC) on the market,like fiber laser,CO2 laser and UV laser etc.


Fiber and CO2 lasers use high-energy pulsed laser beams to act on the surface of PC materials. Under the help of auxiliary additives, light energy is converted into heat energy that leads to melting, foaming, discoloration, or carbonization of the surface of PC materials, thus producing a permanent graphic marks.


However, for transparent or white polycarbonate, it is difficult to use the above laser marking without additives, because it can not hardly absorb the laser. For colored polycarbonate, it is easy to cause degradation ,cracks, cavities on the surface of PC material without additives, which will also reduce the quality of the marks.

UV laser marking for polycarbonate

Fiber and CO2 lasers produce infrared wavelength range resulting in a heat thermal,However,the 355nm ultraviolet laser has the advantages of small focus spot and small heat thermal area that no damage to marking object.So, it is called "cold marking" processing. UV lasers are better used for plastic or polycarbonate materials. In the special marking application of laser engraving,the short wavelength directly produces a photochemical reaction with the polycarbonate without heating.There are no damage to the PC material.So,UV laser marking machine for polycarbonate has played an irreplaceable role in these application.


UV laser marking for polycarbonate

This 3W UV laser marking marker comes with 355nm laser source,which adopts the doubling technique of intracavity frequency and greatly improve the stability of laser.With high beam quality, and a small focus diameter,which is very suitable for fine marking.


UV laser marking for polycarbonate



  • Narrower pulse width and smaller heat affection contribute to generate peak power.
  • Higher pulse repetition frequency meets the need of quick marking and high production efficiency.
  • High efficiency of the photoelectric conversion and long lifespan.
  • Higher pulse stability, namely better pulse consistency of laser produces the same carving effect,very suitable for precision marking.
  • Support many format from Auto-CAD, PLT, BMF, AI, JPG, etc.
  • Superior performance, good stability, high conversion rate and low energy consumption.
  • Automatic in a rotary table (optional item), convenient marking, fast speed, high efficiency.
  • It can mark date,text,number,code and two-dimension code etc.
