Laser and material processing technology

Laser processing technology is an advanced processing technology that uses the characteristics of the interaction of laser beams and substances to cut, weld, surface treat, drill and micro-machine materials (including metals and non-metals). It has been widely used in automobiles, Important sectors of the national economy, such as electronics, electrical appliances, aviation, metallurgy, and machinery manufacturing, play an increasingly important role in improving product quality, labor productivity, automation, pollution-free, and reducing material consumption.
Jeppe fiber laser uses pulsed main oscillation power amplification fiber laser system (Master-Oscillator Power Amplifier Fiber Laser System, MOPA) has the advantages of fast response speed, good beam quality and high reliability, in industrial processing, 3C industry and precision welding, etc. Widely used in the field.

Laser marking system
Laser marking technology is one of the largest application fields in laser processing. Laser marking is the use of high-energy density laser to locally irradiate the workpiece, causing the surface material to vaporize or produce color changes through temperature, thereby leaving permanent marks. Laser marking changes the position of the output beam through the deflection of the galvanometer, and then focuses the laser into a micrometer sized focusing spot through a lens, achieving fine marking of a large format. The extremely thin laser beam after focusing is like a tool, which can remove the material on the surface of the object point by point. Its progressiveness lies in that the marking process is non-contact processing, which does not produce mechanical extrusion or mechanical stress, so it will not damage the processed object. Since the size after laser focusing is very small, the heat affected area is small, and the processing is fine, it can complete some processes that cannot be achieved by conventional methods.
