Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus etching intricate patterns, trademarks, and text. Laser marking machines are mainly classified into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are primarily used in applications requiring higher precision and finer details. Applications include electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.
Laser marking uses a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved through evaporating the surface material to expose the deeper material, or through light energy causing chemical and physical changes in the surface material to "etch" a mark, or through light energy burning away part of the material to reveal the desired pattern or text.
