Laser engraving machines use a laser beam to permanently mark the surface of various materials. The marking effect is to expose the deep layer of the material through the evaporation of the surface material, or to "carve" the trace through the chemical and physical changes of the surface material caused by light energy, or to burn part of the material through light energy, thus showing the need for etching. pattern and text. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tools and accessories, precision instruments, glasses clocks, jewelry, auto parts, plastic buttons, building materials and PVC pipes. Compared with traditional mechanical metal engraving, laser has many advantages in metal engraving: 1. Laser engraving does not need to be in contact with the workpiece to be engraved, which saves a lot of fixtures and tools, and the marked workpiece will not generate internal stress, ensuring The original precision of the workpiece. 2. No corrosion to the working surface, no "tool" wear, non-toxic and pollution-free. 3. The high precision of laser engraving is especially suitable for processing complex graphics. 4. The marking will not fade due to environmental relations (touch, acid and reducing gas, high temperature, low temperature, etc.). ), with high anti-counterfeiting. 5. Non-contact: Laser marking is a non-mechanical "light knife" that can print marks on any regular or irregular surface. 6. Low operating cost: fast marking speed, one-time marking, low energy consumption and low operating cost. Although the equipment investment of laser marking equipment is larger than that of traditional marking equipment, the operating cost of using laser marking equipment is much lower.
