Laser marking machines use laser beams to mark permanent surfaces of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to “mark” the chemical physical change of the surface material through light energy, or burn off some of the material through the light energy to show the required etching. Pattern, text. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipe, medical equipment and other industries.

How can a laser marking machine play deeper?

1. From the laser's power range, increasing the laser power will directly increase the depth of laser marking. However, it must be remembered that once the power of the laser is changed, the laser power supply, the laser chiller, the laser Q-switching system, and the laser mirror can be replaced and the cost will increase. The workload will also increase.

2. From the point of view of the laser, optimizing the beam quality of the laser will also increase the intensity and depth of the laser marking machine. This method is processed by generating lasers, such as tamping the laser cavity, such as replacing a good laser material, a laser crystal, or replacing a higher-grade gas, replacing a more reliable and reliable laser pumping source, and a laser. All mirrors and output mirrors and other measures.

3, from the point of laser light spot treatment, the use of high-quality laser group can achieve a multiplier effect. For example, the use of a good beam expander allows the spot to expand through it to produce a perfect spot that resembles a Gaussian beam. The use of a high-quality F-field mirror allows the laser passing through to have a better light focus and a better spot. The energy used in the effective web spot is more even.

4. If the above three basic methods cannot be changed, the laser marker can achieve a better depth by replacing the field lens with a shorter focal length.
