Kitchen utensils are closely related to family life and are indispensable in people's daily life. They mainly include: range hoods, microwave ovens, refrigerators, dishwashers, toasters, rice cookers, electric kettles, induction cookers, ovens, integrated stoves, etc. . The information content identification such as the icon logo and parameters on the kitchen utensils is an important identification factor for the appearance of the kitchen utensils. Using a fiber laser marking machine, a high-energy-density laser is used to locally irradiate the surface of kitchen products, so that the surface material vaporizes or undergoes a chemical reaction of color change, thereby leaving a permanent mark.
