Laser marking machine is a device that uses laser beam to permanently mark the surface of various materials. It uses the high energy density of laser to quickly evaporate or oxidize part of the material on the surface of the substance, leaving the required mark. The working principle of the laser marking machine is based on the physical process of interaction between laser and matter. When a high-energy laser beam strikes a material surface, the material absorbs the laser energy and converts it into heat energy. This thermal energy causes localized areas on the surface of the material to rapidly heat up to evaporation or oxidation temperatures, thus forming marks.
Advantages of laser marking machines
1. High precision: Laser marking machines have extremely high precision and resolution, and can mark on tiny sizes to meet high-precision requirements.
2. High efficiency: The marking speed of the laser marking machine is very fast, and it can complete a large number of marking tasks in a short time and improve production efficiency.
3. No pollution: The laser marking process does not produce any harmful substances, is environmentally friendly and meets environmental protection requirements.
4. Durability: The marks formed by laser marking are extremely wear-resistant, corrosion-resistant and high-temperature resistant, and can remain clear and readable for a long time.
Because laser marking machines have the advantages of high precision, high efficiency, and no pollution, they have been widely used in many industries.
Laser marking machines can be divided into many types. According to different lasers, they can be divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines and YAG laser marking machines. Different types of laser marking machines have different characteristics and scope of application. For example, CO2 laser marking machines are suitable for marking non-metal materials, such as paper, plastic, leather, etc.; while semiconductor laser marking machines are suitable for marking metal materials, such as stainless steel, aluminum alloys, etc.
In addition to being classified by laser, laser marking machines can also be classified according to parameters such as laser wavelength, laser energy, and marking speed. Laser marking machines with different parameters are suitable for different marking needs and material types.
Laser marking machines are widely used in many industries, such as electronic components, integrated circuits, electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, and building materials, PVC pipes, etc. In these industries, laser marking machines can be used to mark product numbers, production dates, brand logos and other information to improve product traceability and brand image. In addition, with the development and innovation of technology, laser marking machines can also achieve more functions and applications, such as QR code marking, 3D marking, color marking, etc., providing more choices and application scenarios for various industries.
