What material can 355nm UV laser mark

Lasers are one of the great inventions of mankind since the 20th century, after nuclear energy, computers, and semiconductors. With the rapid development of science and technology, the laser field has developed rapidly. It can be used in industry, agriculture, measurement, detection, communication, information processing, medical treatment, military and other aspects, greatly improving the productivity of society.

Under the current trend of rapid development, in order to better adapt to the market, many enterprises often endow new products with new values ​​through technological reforms. At the same time, in order to meet people's individual needs for commodities, and to reduce production costs, beautiful design, individual trademarks, etc., the unique advantages of ultraviolet lasers have been widely used in various micro-processing industries.

So if you want to have a stable and fine marking effect, first of all, the laser must be stable enough. For example, the TR-W-UV03 ultraviolet laser of Gelai Laser is 355nm, with excellent and stable beam quality (M2<1.5), and has been strictly monitored in all frequency ranges. At the same time, its pulse width is short (<15ns@30KHz), and its spot characteristics (spot ellipticity>90%) can be controlled by Rs232 remote computer, which can ensure fine marking effect.

egg marking

Now we find that many eggs sold in large supermarkets are marked with signs indicating where the eggs come from! The engraving is clear, and its traces cannot be erased without destroying the surface quality. In fact, it is processed by ultraviolet laser, which is simple and convenient, and can realize flow operation.

3C material marking

With the advent of the 5G era, the development of the 3C industry (computer, communication and consumer electronic products) will be accelerated. At the same time, 3C electronic products will be upgraded in the direction of high integration and high precision, and the internal components of their products will become smaller and smaller. , the precision and electronic integration are getting higher and higher. In product development, the pursuit of lighter, thinner, and more portable designers has led to new materials. The laser can be used for text generation, pattern generation, bar code, two-dimensional code, etc., and can be controlled by computer remotely, which can well meet various proofing needs.

metal craft

The daily use of stainless steel chopsticks, knives and forks, spoons, bracelets, rings and other metal utensils, practical or simple decoration can no longer meet people's current needs. Try and think about it, if you add an artistic beauty to ordinary tableware, such as text or pattern modification, etc., it is estimated that it can make people more fond of it, and the valuation can also be improved a lot.

Precision proofing

In the past, when watching movies, many hidden secrets would be engraved in pendants. Such scenes are very common. The words in the crystal cannot be seen by the naked eye, and the mystery can only be discovered under the microscope. At that time, I often wondered, how can I put every word or rune on the thumb-sized ornament? Ultraviolet laser is controlled remotely by computer, and precise proofing can be realized according to what you want to describe.

Putting your own unique logo on the product will not only let consumers know the source of the product and trace it, but also dispel consumers' various concerns when consuming. So a good laser, in addition to the diversification of functions, must also have a long life and durability. After all, the price of ultraviolet lasers is in the thousands or even tens of thousands, and laser marking is an industry with small profits but quick turnover. Therefore, only when the laser operates stably for a long time, the mechanical performance of the laser is reliable.
