Comparison of UV laser marking and CO2 laser marking

In recent years, intelligent manufacturing technology has been continuously upgraded, and the demand for fine processing is increasing. UV marking and fiber laser marking are increasingly favored by users. In particular, the UV laser marking machine realizes "cold processing", with fine processing effect, accurate positioning, small heat-affected area, and more detailed and exquisite pattern effect, which begins to gradually replace the status of CO2 laser marking and marking machine. So, what are the advantages of UV laser marking machine and CO2 laser marking machine?

PS: UV laser marking machine is suitable for ultra-fine processing industry, and the equipment cost is higher.

What are the advantages of UV laser marking machine and CO2 laser marking machine?

The advantages of CO2 laser marking machine:

CO2 laser marking machine has become one of the commonly used laser marking forms due to its high efficiency and beam quality. It also works with a variety of non-metallic materials, including wood, acrylic, glass, textiles, plastics, foils and films, leather, and even stone. CO2 laser marking is mainly used for food, medicine or wine packaging, electronic components, integrated circuits, electrical appliances, mobile communications, building materials and PVC pipes, etc. It uses the interaction of laser energy and materials to leave permanent traces on the surface of objects, which is a revolutionary alternative to traditional techniques such as inkjet, silk screen printing, and knife engraving. This technique can engrave beautiful designs, logos, dates or text on the surface of a product.

Advantages of UV laser marking machine:

The UV laser marking machine is a laser with a wavelength of 355nm. Due to its short wavelength and narrow pulse characteristics, it produces a very small focused spot and maintains a minimal heat-affected zone, which enables it to be processed very precisely while minimizing mechanical deformation of the material. It can not only provide extremely fine processing effect, but also maintain good positioning accuracy, which is the advantage of UV laser marking machine. UV laser marking is mainly used for surface marking of packaging bottles of pharmaceuticals, cosmetics, food and other polymer materials, flexible PCB board marking, scribing, silicon wafer micro-hole, blind-hole processing, LCD liquid crystal glass two-dimensional code Marking, surface drilling of glassware, etc.

UV laser marking machine and CO2 laser marking machine is better

1. In the application fields with high precision requirements, such as glass, chip, and various PCB board marking, UV laser marking machine is obviously better than CO2 laser marking. Especially in various PCB material applications, UV laser marking machine is considered to be the best choice.

2. From the perspective of market performance, UV laser marking machines seem to far exceed CO2 laser marking machines. In 2017, the national shipments of UV laser marking machines soared by more than 3000% compared with 5 years ago.
