Today, people have increasingly high demands for quality of life, and accurate and fast traceability of product information has attracted the attention of people from all walks of life. The country has also introduced a series of corresponding policies for product labeling. Laser marking machines have gradually entered people's vision. As the name suggests, they are machines that print various labels on product packaging or workpieces. Their function is not only to promote and advertise, but also to accurately and quickly trace and manage products. It has been widely used in many industries such as automotive and motorcycle parts, pharmaceuticals, food, electronic information, daily necessities, and craft gifts.

Laser marking machine, also known as laser engraving machine, laser coding machine, laser spray coding machine, etc., has different names in different regions and industries. Its marking principle is to use a high-density laser beam to irradiate the workpiece, absorb laser energy on the surface, and cause the material surface to undergo deformation, melting, ablation, evaporation and other phenomena, thereby forming permanent marks. Some materials, such as special plastics, absorb heat and expand on the surface of the workpiece, forming a permanent protruding mark, but only for a very few materials.

Different depths of concave markings can be printed based on laser power, printing speed, marking frequency, and processing materials. According to different lasers, laser marking machines can be divided into semiconductor laser marking machines, CO2 laser marking machines, fiber laser marking machines, etc. They have different marking effects for different marking materials.
