The wavelength of UV laser light is around one-third (355 nm) of that of standard wavelength lasers (1064 nm). The name “UV laser marking machine” comes from its wavelength being in the ultraviolet portion of the light spectrum.

Marking using these lasers is called “Cold Marking,” which refers to how they can perform marking and processing with minimal heat damage due to their incredibly high absorption rate on a variety of materials. UV laser marking is ideal for applications that require high contrast or minimal product damage.

UV laser marking machine is developed with 355nm Ultraviolet laser source for plastic, silicon, glass, ceramic, which adopts a third-order intracavity frequency doubling technology. Compared with infrared lasers, 355nm UV laser has a very small focus spot, which can greatly reduce the material mechanical deformation and processing heat influence is small. UV laser marking machine 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).

UV laser marking machine is very mature relatively simple, direct use laser light through the expanded beam shaping after out to connect to the galvanometer optical system, by high energy beam to the workpiece surface, material formation on the surface of gasification off pattern. In short laser processing system refers to the energy produced by laser beam to the surface of the workpiece material moment gasification formation of cutting, perforation or surface design. The common three types of laser processing technology on the market is divided into vibration mirror machining, collimating mirror machining as well as the objective, its principle is through a variety of reflective lenses make laser energy to focus on a point, through mobile work platform, or move through the lens turn back beam forming processing.

Ultraviolet laser marking is a type of cold engraving method. The engraving process is called the “photoetching” 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.

• UV laser marking machine adopts 355nm pumped UV laser device, so as to get smaller diameter of focusing spot and fine marking effect.
• The metal absorb UV higher than infrared and therefore more suitable for UV laser marker marking on metal and glass materials compared with infrared pump machine.
• 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.

1. Flexible processing

Laser marking can be used on many products in a variety of industries, including aerospace, automotive, defense DOD, medical and electronic components. Apple Rubber uses laser marking on virtually any o-ring or seal where product identification is required.

In many industries, product authenticity and traceability is required by law. Automotive companies, for example, use part traceability to quickly determine when and where the part was produced in the case of component failure, which helps for product recalls. Because of the importance of product identification, using a flexible and reliable marking technique is critical.

2. Overall speed

In traditional ink marking, printing equipment is often mechanically complex, requiring longer downtimes for maintenance and frequent cleanings. With UV laser marking, there is no prolonged downtime associated with cleaning or fixing a printer, and the overall engraving process is extremely quick and simple.

UV lasers are better absorbed than other wavelengths and marking techniques by virtually all materials, requiring less power to produce a clear mark. This makes the process even simpler since UV laser marking ensures a high-quality, high-contrast mark in one application.

3. Maximizes authenticity

UV lasers create easy-to-read marks that are far superior to printed marks or labels. Apple Rubber uses a high-quality laser that can focus in on smaller spot sizes and produce a high peak power, leading to crisp, clear marks on o-rings and seals. This ensures that parts can be clearly identified and their markings cannot be altered or tampered with.

In the pharmaceutical industry, counterfeiting has become a huge issue with many social and economic implications. Since pharmaceutical manufacturers are limited in what types of markings they can use, they must choose an option that is tamper-proof, easy to read, compatible with their specific environment and cannot alter the product. Because of these requirements, laser marking is the best choice in this industry and many others that require complete authenticity in their products.

4. Minimizes contamination

While the ink in traditional marking methods is non-toxic, the printing equipment often utilizes lubricants and solvents that can become airborne and contaminate printed products. Medical manufacturing often requires completely sterile products that must be produced in a classified cleanroom. In this case, traditional marking would not be acceptable.

During the laser marking process, the marking device does not come into direct contact with the product, allowing for clean operation with minimal contamination. This creates a product identification option for industries that require sterile products and ensures that outside materials will not cause future contamination of a product.

Considering the list above, the end-users of this technology and this equipment span multiple businesses. For instance, they can be from food and beverages to industrial and medical products.

Below are a few example images of products describing possible end uses. From package marking for traceability to identification marking on electronics, the UV laser engraver is a proficient tool for achieving the marking.

Over the last decade, infrared fiber lasers became the dominant solutions due to their cost, performance, and size advantages. However, recent application studies have shown that wavelength in the range of green and UV lasers are providing performance and flexibility advantages that provide benefits for system integrators and end-users alike.

Furthermore, advances in compactness, weight, size, and performance parameters, as well as demonstrated reliability, ruggedness, and durability enabled UV lasers to resurface for laser marking applications.
