What Is A UV Laser Marking Machine?
Ultraviolet laser marking machine is one kind of laser marking machines, it is developed using a 355nm ultraviolet laser. The machine uses third-order cavity frequency doubling technology compared with infrared laser. To a large extent reduce the mechanical deformation of the material and the processing heat effect is small, because it is mainly used for ultra-fine marking and engraving, especially suitable for food, pharmaceutical packaging materials marking, micro-holes, high-speed division of glass materials and silicon Wafers are used in complex graphic cutting applications.
How Does A UV Laser Marking Machine Work?
In the field of modern precision machining, the traditional laser marking machine uses laser thermal processing technology, and the fineness has a restrictive development. Under such a background, the ultraviolet laser marking machine has become the darling of the new era.
The UV laser marking machine uses a cold working process. The process is called the "photoetching" effect. "Cold working" (UV) photons with high load energy can break the chemical bonds in the material or the surrounding medium, so that The material is destroyed by non-thermal process, the inner layer and the nearby area do not generate heating or thermal deformation, etc. The final processed material has smooth edges and extremely low carbonization, so the fineness and thermal impact are minimized, which is the laser A big leap forward in technology. The reaction mechanism of ultraviolet laser processing is achieved by photochemical ablation, that is, relying on the laser energy to break the bonds between atoms or molecules, making them small molecules vaporize and evaporate to expose the deep layer of the material, thus "engraving" The pattern text is needed, which is simply to use laser beam to print permanent marks on the surface of various substances.

What Are The Advantages And Benefits of UV Laser Marking?
Ultraviolet(UV) laser marking machine is one kind of CNC laser marking machines. The traditional laser marking machine uses the laser thermal processing technology, and the improvement space in terms of fineness has a restrictive development, while the ultraviolet laser marking machine The standard machine is a cold process, so the fineness and thermal impact are reduced to a lower level, which is a big leap in laser technology.
(1).The beam quality is good, the focusing spot is extremely small, so it can be super fine marking, special material marking,
(2).In addition to the copper material, the ultraviolet laser is more suitable for processing.
(3).The heat-affected area is extremely small, which will not cause thermal effects and will not cause material scorching;
(4).Fast marking speed and high efficiency;
(5).The machine has stable performance, small size, low power consumption and other advantages
How It Works
How To Choose The Right UV Laser Marking Machine?
There are many types of UV laser marking machines on the market, the customers are get confused of which UV laser marking machine will be the best for their work. We list some points in this article explaining in detail what you should pay attention to when choosing an ultraviolet laser marking machine.
Due to the different power and laser types of various ultraviolet laser marking machines on the market, the scope of application of the materials is also different. Increasing the utilization rate of equipment can properly meet its own needs. Therefore, it is necessary to fully consider which models of UV laser marking machines are suitable for production, and choose the UV laser marking machine equipment that meets the actual needs according to the specific actual situation.
Selection of the performance of ultraviolet laser marking machine, such as: optical characteristics and control characteristics. The optical characteristics mainly include spot size, focal plane height, spot position, and spot incident angle. The control characteristic is the choice of feedback control mode and power waveform. The optical characteristics of the UV laser marking machine can be determined during proofing, and the user can intuitively determine the marking effect when the product is initially trial-produced.
Quality and stability of use are also very important indicators for the purchase of UV laser marking machines. Now the product development cycle is short, and the replacement is getting faster and faster. There are more product diversity, prototype production, and mass production. How to complete customer orders with quality and quantity, maintain corporate reputation, and enhance corporate competitiveness are also placed in every Difficult and huge tasks in front of each operator, the purchase of stable processing equipment is the premise and foundation.
4.Technical Support & Service
Choose an ultraviolet laser marking machine, try to choose a brand with a high market share, a sound after-sales service system, many after-sales service outlets, and a long-term market test. It is not possible to buy UV laser marking machine products with poor quality and no after-sales service just because of the low price, which will have a huge impact on the company's production.
