2023 Best UV Laser Engraving & Marking Machine for Sale

UV laser marking and engraving machine is used for material processing with physical interaction between the high energy pulsed UV laser and the material surface in order to vaporize, ablate the material surface.

Nowadays, laser processing technology is rapidly entering all sectors of our life and most of them are related to metal material processing, which occupies more than 80% of the overall laser processing applications. Because iron, copper, aluminum, alloy are hard materials that have very good absorption of the laser.

For most common metal laser processing, it is only necessary to know the right laser power, and the processing research requirements actually is not be very high. But in fact, in my daily life and high-end manufacturing fields, a large number of non-metallic materials like soft materials, thermoplastic materials, heat-sensitive materials, ceramic materials, semiconductor materials, and brittle materials such as glass, plastic, ceramic. If these materials are processed by laser, the requirements for beam performance, degree of ablation, and material breakage control are very strict and it often requires ultra-fine processing. The precision requirement is normally with a micrometer or even nanometer level. The use of common infrared lasers is difficult to achieve this high requirement, but ultraviolet laser marking and engraving machines are very suitable choices.

UV laser marker and engraver are with industrial ultraviolet solid-state lasers. The 355nm UV laser is be obtained by tripling the 1064nm infrared all-solid laser and the pulse width has been successfully developed from nanosecond to picosecond level.

Currently, the cost of a UV laser processing machine is still high and it is difficult to have high power. UV laser marking and engraving machine is often considered as cold processing, which is very suitable for processing soft materials, thermoplastic materials, heat-sensitive materials, ceramic materials, semiconductor materials, and brittle materials such as glass, plastic, ceramic.

UV engraver and marker system are limiting thermal effect, reducing damage to the workpiece, and maintaining the integrity of workpieces while processing.

When a UV laser machine interacts with many materials, it does not only ablate and vaporize the surface material with heat, but its UV radiation even directly changes the structure of molecular chains.

It has obvious advantages in micrometer and nanometer level ultra-fine processing of heat-sensitive materials, flammable materials, hard and brittle materials, ceramic materials like glass, plastics, paper, ceramic, etc.

With the rapid development of infrared picosecond laser machines and their price has dropped significantly. There seems to be a trend that nanosecond UV laser machines will be replaced by picosecond IR one.

These two types of laser machines in the fine laser processing field certainly have a certain degree of competition, such as screen glass cutting, silicon wafer scribing, sapphire cutting, and micro-hole drilling.

The current high-power infrared picosecond laser equipment is very high. UV laser marking and engraving machine relatively with lower price, and it could also achieve the target effect of ultra-fine processing. Nanosecond UV laser marker and engraver is much more advantageous in terms of cost-effectiveness in the laser processing field of flammable materials, ceramic materials, plastics, paper, and other non-metallic products.

As the application of UV laser markers and engraver equipment is getting closer to our life, it has a natural characteristic in the industrial field.

Now it has become one of the mainstream industrial-grade lasers with its short wavelength, narrow pulse width, fast speed, high material absorption rate, and high peak laser power. UV laser engraving and marking technology is becoming more and more mature, the application fields are getting wider and wider, and more and more popular in more industries. At present, the UV laser machine in the market is used for marking and engraving on plastic, glass, ceramics, crystal, and some metal materials.

The UV laser machine is also called a cold processing machine, which is different from the fiber machine known as thermal processing equipment. It uses high-density laser energy to irradiate on the target area of the workpiece to cause vaporization or color change of the photochemical reaction on the material surface to achieve a permanent mark.

UV laser marker and engraver require no consumables, and the final marking effect is precise and beautiful. Replacing the traditional processing method with an ultraviolet laser system has become an irreversible trend.

Laser Marking & Engraving on Plastic 3C Products

3C products becomes popular in recent years along with the development of the electronic industry, and the processing process is becoming more and more precise to meet the higher aesthetic demand of modern people. At the same time, enterprises urgently need to find a new processing method to save production costs and make a permanent mark on products.

The UV laser marker and engraver have a very small heat effect, fast speed, and high accuracy. Most importantly, UV laser marking machines on plastic will not cause deformation of the original parts, yellowing or blackening surface, and other unwanted phenomena.

Laser Marking & Engraving on PCB

As we all know that many parts on printed circuit boards are made up of precious metal materials, including gold, silver, and copper. To manage those small metal parts, a distinguished logo, serial number, the text is always marked or engraved.

With the traditional inkjet or sandblast marking technology, it is difficult to achieve such a fine process standard. The PCB UV laser marker and engraver is with very small beam size and short pulse width for high quality and small size data marking and engraving.

Laser Marking & Engraving on Glass

Glass could be seen everywhere in our daily life. Glass products can be used for storage, decoration, and so on. We often see the image or text mark on some glass cups, which is not colorful but very beautiful. It is permanent or will not cause any pollution. Additionally, compared with manual engraving. the surface is more flat and smooth.

Laser Marking & Engraving on Ceramic

Ceramic materials are applied for thousands of years and now could be found in every industry every day like decorative items, electronics, and construction materials.

Electronic ceramic applications became mature in the last century, with a wider range of applications field such as heat sink substrates, piezoelectric materials, resistors, semiconductors, biological applications, etc.

In addition to the traditional ceramic processing process, ceramic laser marking and engraving machines become widely used for ceramic processing due to the increasing new applications with ceramics materials.

In terms of absorption rate during marking and engraving, CO2 and fiber machine is difficult to meet the demanding requirements. The UV laser system is an ideal choice for ceramic processing.
