Sinotech Laser solutions are widely used in various stages of finished and unfinished metal and wire products, as well as the automotive, medical, and infrastructure industries. With professional User friendly software you can mark Lot Code Engraving,Part Number Engraving,2D Code Engraving ,brand logos and so on.


Laser marking is one of the most popular marking technologies in industrial production. Metals, plastics, ceramics, and other materials can be marked with lasers by different laser wavelengths range from 1064 nm (infrared), 532 nm (green), and 355 nm (ultraviolet). As a production tool, lasers can be applied to digital, text, trademark or readable codes, such as data matrix codes with high density information and arranged in limited spaces at different scales.

In this way, high-speed marking machine greatly shorten the time of the production process, while at the same time not requiring expensive up-front work and nor final finishing work. In addition, laser marking machines can be easily integrated into production lines. With the user-friendly program interface, you can quickly switch to a new working process and having a fine product that is highly repeatable and resistant to aging and wear.

In plastic marking applications, the potential of using laser marking machines are far from being realized. In addition to the benefits mentioned above, the increasing popularity of frequency-doubled lasers and triple-frequency lasers, as well as the diversity of materials and processes, is opening up new areas for laser applications in the plastics industry.

Precision marking

For plastic marking, Q-switched solid-stated laser marking machines or fiber laser marking machines are the common types. These lasers typically have an average power of less than 100 W with a pulse duration between 10 and 100 ns. The pulse frequency is up to 120 kHz, and in the case of fiber lasers, it is even up to 1 MHz. In this way, the interaction with the material to be identified can be fine-tuned. Short pulse times result in high pulse peak powers of tens of kilowatts reaching an average of 10W.

The laser is a diode-pumped laser that is energy efficient. They have excellent focusing power and are therefore ideal for fine marking. Diode-pumped solid-state lasers have high beam quality, resulting in a small focus diameter for the laser beam during marking. In this way, it is possible to achieve a precision marking track width as small as 30 m on a small component.
