Many people think that laser marking will cause high radiation to the human body. According to scientific research, the human body can accept radiation within 1000 units. If it exceeds 1000 units, the harm to the human body is very obvious. However, in our daily life, electronic devices such as mobile phones are indispensable, and they all produce radiation. The radiation produced by the laser marking machine during the operation and processing will definitely be produced, but it is much lower than that of the mobile phone, so the damage to the human body is almost negligible. Secondly, it is not true that laser marking machines produce toxic gases. The laser marking machine relies on the heat of the laser to process the surface of the marked object to achieve the marking effect. During the marking process of different materials, a small amount of toxic gas will be produced, but the amount is very small. Plastics, for example, give off large amounts of gas containing carbon monoxide. Secondly, most processed metal materials have stable properties, high density, and a low probability of producing toxic gases. However, less powder is produced if the marking material is aluminum. Therefore, it is recommended that you try to operate under good ventilation conditions and use professional equipment when cleaning. The hazards of lasers may be the most important thing that laser marking machines should know. Lasers are accompanied by high heat, most of which is invisible infrared light. When operating, prevent the direct beam from entering the eyes, and do not place any part of the body under the laser beam marked by the laser, so as not to burn the human skin. The laser emitted by the laser marking machine may also cause damage to eyesight. During marking operations on glass products it is important to be aware of the very high laser brightness. If you keep looking directly, it will cause damage to the operator's vision, and if it takes a long time, it may also cause damage to the lens. Therefore, during the operation of the equipment, you must wear protective equipment and do not look directly at the laser for a long time. To sum up, the laser marking machine produces a small amount of radiation, but the harm to the human body is almost zero. However, if you look directly or directly at the laser, it will cause damage to the eyes. The probability of these situations is relatively small, so you must strictly follow the specifications when operating.
