The basic principle of laser engraving laser that produces a continuous high-energy laser beam from the laser generator, when the laser acts on the printing material, in atomic ground state transition to a higher energy state; in a higher energy state atom is unstable , will soon return to the ground state, when the atom returns to the ground state, will be released in the form of photons or quantum of additional energy by solar energy is converted into heat, the surface of the material to be melted instantly, and even gasification to form a graphic mark . Laser engraving laser engraving means, is carved signs and cause chemical changes in the surface material by physical energy of the laser beam, or portion of the material is burned by light, showing the required etched graphics, text; in accordance with the engraving method It can be divided into lattice engraving and vector cutting. Small metal marking machine is the latest developed a new production of a portable laser can move freely class fonts, pictures, microcode marking and lettering. Dapeng whole new generation of laser marking machine - Portable machines with small size, light weight, flexible, you can always move very easily move laser marking machine wherever you think of. Place the marking machine, connect a computer with Internet access will be free of any marks you want to print.
