Laser marking machine

Laser marking is a high-precision and high-efficiency technology. It has been widely used in various fields. Laser marking can mark a wide range of materials and accurately identify patterns, text and barcodes. It is essential for improving product quality, safety and brand recognition.

Laser marking technology is based on the working principle of a laser. The laser produces a focused laser beam. The laser beam has consistent optical properties. Examples include wavelength, frequency and low scattering. This focused laser beam can be precisely directed on the surface of the material. The material can be subjected to controlled thermal energy.
There are three main types of laser marking: engraving, etching, and color change. The laser beam removes a small portion of material during the engraving process, creating the desired mark. The etching process is similar, but uses a chemical reaction to remove material. In color change, the laser changes the color of the material's surface rather than removing it.
The accuracy and control of laser marking technology depends on several factors. These include laser power, wavelength, focus and marking speed. Adjusting these parameters maintains different depths, accuracy and speeds. It makes laser marking a versatile process.

General categories of laser marking machines:
First, the models are categorized according to their principles and features:
1. According to the laser wavelength: 532nm laser marking machine, 808nm laser marking machine, 1064nm laser marking machine, 10.64um laser marking machine and 266nm laser marking machine. The most widely used is 1064nm.
2. According to the laser: CO2 laser marking machine, semiconductor laser marking machine, YAG laser marking machine, fiber laser marking machine.
3. According to the different laser visibility, divided into ultraviolet laser marking machine, green laser marking machine and infrared laser marking machine.

Second, according to the industry-specific model classification:
1. Fiber laser marking machine
Currently the most widely used model is the use of fiber laser output laser, and then through the ultra-high-speed scanning galvanometer system to achieve the marking function. Fiber laser marking machine electro-optical conversion efficiency, the use of air-cooled, small size, good output beam quality, high reliability, long operating life, energy saving, can be engraved metal materials and some non-metallic materials. Mainly used in the field of high requirements for depth, finish and fineness, such as cell phone stainless steel jewelry, clocks and watches, molds, IC, cell phone buttons and so on. Bitmap marking can produce beautiful pictures on the surface of metal and plastic, marking speed is the traditional first-generation lamp pump marking machine and the second generation of semiconductor marking machine 3 to 12 times.

2. Ultraviolet laser marking machine
Ultraviolet laser marking machine belongs to the cold light or ultraviolet laser marking, is a promising model. Marking, fiber laser marking machine for many products does not produce satisfactory results. Generally speaking, the UV laser marking machine can be in the marking production of printed text, patterns and so on. Will be finer and clearer, mainly used in enterprises with high requirements for text, patterns and other major products. UV laser commonly used in the market are 3W, 5W, 7W, 8W, 10W, 15W.

3.CO2 laser marking machine
Adopting CO2 metal laser, beam expanding and focusing optical system and high-speed galvanometer scanner, stable performance, long service life, maintenance-free.CO2 laser is a laser wavelength of 10.64m gas laser, belonging to the mid-infrared wavelength.CO2 laser has relatively high power and relatively high electro-optical conversion rate. CO2 lasers use CO2 gas as the working substance.
