Desktop UV laser marking machine is a type of cold laser engraving system with Ultraviolet laser source for plastics, including PP (polypropylene), PC (polycarbonate), PE (polyethylene), ABS, PA, PMMA, silicon, glass and ceramics.
UV laser marking machine is developed with a 355nm Ultraviolet laser source for plastic, silicon, glass, and ceramic, which adopts a third-order intracavity frequency doubling technology. Compared with infrared lasers, a 355nm UV laser has a very small focus spot, which can greatly reduce the material mechanical deformation, and the processing heat influence is small. UV laser marking machines are mainly used for ultra-fine marking and engraving. It is especially suitable for food and medical packaging materials, marking, micro-holes, high-speed division of glass materials, and complex pattern cutting of silicon wafers.
Ultraviolet laser marking machines are widely used in some high-end markets for fine processing. For example, some high-molecular materials for cosmetics, marking of flexible PCB boards, micro-controlling of silicon wafers, and 2D code marking of LCD liquid crystal glass, various metals, plastics, building materials, communication equipment (mobile phone screens, mobile phone cases, iPhone cases, Huawei mobile phone cases, Samsung mobile phone cases, OPPO mobile phone cases, XIAOMI mobile phone cases).
The principle of the UV laser marking system is similar to the most common laser marking machines, which use laser beams to make permanent marks on the surface of various materials. The effect of marking is to directly break the molecular chain of the substance through the short-wave laser (different from the evaporation of the surface substance produced by the long-wave laser to expose the deep substance) to reveal the pattern and text to be etched.
Ultraviolet laser marking is a type of cold engraving method. The engraving process is called the "photo etching" effect. "cold processing" has a very high load of energy (ultraviolet) photons, which can break the chemical bond in the material (especially organic material) or the surrounding medium. To cause the material to undergo non-thermal process damage. There is no heating or thermal deformation on the inner layer and nearby areas of the processed surface. The high-energy molecules of ultraviolet photons directly detach the molecules on the metal or non-metal materials that need to be processed. However, this detachment causes the molecules to separate from the material. This way of working does not generate heat, because it does not generate heat. As a result, the method of UV laser processing has become cold processing, which is the source of the difference from traditional fiber laser marking systems.
The UV laser marking machine is based on its unique low-power laser beam, so it can perform ultra-fine marking and special material marking. It is the 1st choice for customers who have higher requirements for marking effects. It is especially suitable for the high-end market of ultra-fine processing, with fine effects and clear and firm markings.
The Ultraviolet laser engraving machine has high beam quality and small focused spot, which makes marking finer and higher definition; the heat-affected area is small, no thermal effect is generated, and the deformation or scorching of the processed material is avoided. The applicable materials are particularly wide, which solves the problems of insufficient detail and poor effect of fiber laser engraving for many materials. The marking speed is fast and the efficiency is high. The function of online flying marking can be realized on the assembly line.
1. A UV laser engraving machine adopts 355nm pumped UV laser device, to get smaller diameter of focusing spot and fine marking effect.
2. The metal absorbs UV higher than infrared and is therefore more suitable for UV laser marker marking on metal and glass materials compared with infrared pump machines.
3. A narrower pulse width of UV laser makes a shorter time of processing on materials, thus the materials avoid being deformed or burnt due to thermal.
4. With a smaller heat-affected area and a more beautiful marking effect, our products' UV laser marking system can meet customers with higher marking requirements.
5. The UV laser engraving machine is equipped with a safety shield, which can effectively isolate the purple radiation, to ensure the safety of UV laser marker operators.
6. UV laser engraver is equipped with a professional water cooling machine, air-cooled water circulation cooling, with water-cooled high efficiency and air-cooled small size.
7. Low energy consumption, environmentally friendly, no consumables. Little affected area, no heat effect, without material burned problem.

Selecting the ideal UV laser marking machine is a crucial choice that can affect the productivity, caliber of your products, and overall profitability of your company. Given the abundance of possibilities, it's critical to consider vital criteria before making a purchase. The key factors to take into account when choosing the ideal UV laser marking system for your requirements are broken down below.
1. Understand Your Material and Application Needs
Before purchasing a UV laser marking machine, identify the materials you will be working with, such as plastics, glass, ceramics, or silicon. Different materials react differently to laser marking, so ensuring compatibility is crucial. Also, consider the type of marking—whether it's engraving, etching, or micro-marking—so you choose a machine that meets your specific requirements.
2. Evaluate Laser Power and Wavelength
The 355nm wavelength of UV laser machines is ideal for ultra-fine, high-precision marking, but the power level matters too. Machines with 3W to 10W power are typically suitable for most applications. Higher power means faster processing speeds, but excessive power may not be necessary for delicate or intricate markings. Choose wisely based on your workload and material sensitivity.
3. Consider Marking Speed and Efficiency
If your business requires high-volume production, you need a UV laser marker with fast marking speeds and stable performance. Look for machines that support on-the-fly marking (dynamic marking on production lines) to maximize efficiency. A slow machine can create production bottlenecks, reducing overall output and profitability.
4. Check for Precision and Resolution
A good UV laser marker should offer high resolution (as fine as 0.01mm line width) and repeatable accuracy (±0.003mm) to ensure crisp, clear, and permanent markings. If your business deals with small components, circuit boards, or intricate designs, precision is a top priority. Low-quality machines may leave blurry or inconsistent marks.
5. Assess Cooling and Heat Management System
UV laser marking machines generate heat, but effective cooling systems help maintain stability. Most UV laser markers come with air-cooled or water-cooled options. Water-cooled systems provide superior heat dissipation for extended operation, making them ideal for high-intensity usage. Investing in proper cooling ensures longevity and consistent performance.
6. Prioritize Software Compatibility and Ease of Use
A user-friendly interface and versatile software are essential for smooth operation. Look for machines that support EZCAD or other widely used laser control software for seamless design imports and parameter adjustments. An intuitive system reduces operator training time and minimizes errors, boosting overall productivity.
7. Look for Safety Features and Compliance
Since UV laser technology emits high-energy beams, safety is crucial. Choose a machine with a protective enclosure, laser shielding, and automatic shut-off features to ensure workplace safety. Additionally, check for CE, FDA, or ISO certifications, which indicate compliance with international safety and quality standards.
