The so-called laser marking is the use of laser beams to carve permanent marks on the surface of materials or inside transparent materials. Laser beam can produce chemical and physical effects on matter! When the substance instantly absorbs laser light, it produces a physical or chemical reaction, so as to engrave marks 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 garment fabrics, medical packaging, wine packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell famous brands, craft gifts, electronic components, leather and other industries.
It can carve metal and a variety of non-metallic materials. It is more suitable for processing some products requiring fine and high precision.
It is used in electronic components, integrated circuit (IC), electrical engineering, mobile phone communication, hardware products, tool accessories, precision instruments, glasses, clocks, jewelry, auto parts, plastic keys, building materials, PVC pipes, medical devices and other industries.
The materials used include: ordinary metals and alloys (all metals such as iron, copper, aluminum, magnesium and zinc), rare metals and alloys (gold, silver and titanium) metal oxides (all kinds of metal oxides), special surface treatment (phosphating, aluminum anodizing and electroplating surface), ABS materials (electrical appliance shell and daily necessities), ink (transparent keys and printed products), Epoxy resin (packaging and insulating layer of electronic components).
Laser surface treatment is to use laser beam for heating to quickly melt a certain depth of thin layer on the workpiece surface. At the same time, alloy elements are coated on the workpiece surface by vacuum evaporation, electroplating, ion implantation and other methods, which are fully integrated with the base metal under laser irradiation. After cold setting, the thickness of 10 ~ 1000 is obtained on the die surface μ M alloy layer with special properties, and the cooling rate is equivalent to quenching
