The so-called laser marking is to use the laser beam to carve a permanent mark on the surface of a material or inside a transparent material. Laser beam can produce chemical and physical effects on matter! When the material instantly absorbs the laser light, a physical or chemical reaction occurs, so as to carve traces or show patterns or words! So it is also called laser radium carving.
It can carve a variety of non-metallic materials. It is used in clothing fabric, medical packaging, wine packaging, architectural ceramics, beverage packaging, fabric cutting, rubber products, shell brand, craft gifts, electronic components, leather and other industries.
It can carve metal and many kinds of nonmetal materials. It is more suitable for some products with high precision.
It is used in electronic components, integrated circuit (IC), electrical engineering, mobile communication, hardware products, tool accessories, precision instruments, glasses, clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes, medical devices and other industries.
The materials used include: common metals and alloys (iron, copper, aluminum, magnesium, zinc and all other metals), rare metals and alloys (gold, silver, titanium) metal oxides (all kinds of metal oxides can be used), special surface treatment (phosphating, aluminum anodizing, electroplating surface), ABS materials (electrical appliances shell, daily necessities), ink (transparent keys, printing products), Epoxy resin (packaging and insulating layer of electronic components).
surface treatment
Laser surface treatment is to use laser beam to heat and melt a certain depth of thin layer on the surface of the workpiece. At the same time, the alloy elements are coated on the surface of the workpiece by vacuum evaporation, electroplating, ion implantation and other methods. Under laser irradiation, the alloy elements are fully fused with the base metal. After cooling, the thickness of the die surface is 10 ~ 1000 μ M alloy layer with special properties, the cooling rate is equivalent to quenching
