The purchase of laser marking machines is mainly based on the characteristics of the product, because laser marking machines with different characteristics target different product materials. Generally, laser marking machines are mainly divided into three categories, fiber laser marking Machine (see the functions of fiber laser marking machine), ultraviolet laser marking machine, co2 laser marking machine, these are the three types commonly used in the market after all. Direct burning and etching by laser is a permanent mark, which cannot be erased and will not fail, deform and fall off. It is suitable for anti-counterfeiting and anti-smuggling, and realizes the requirements of product traceability. Laser processing is optical contact, non-mechanical contact, and no mechanical stress, so it is especially suitable for applications with high hardness (such as cemented carbide), high brittleness (such as solar silicon wafers), high melting point and high precision (such as precision bearings) Use in other occasions.
Laser processing has a large energy density, short time, small heat-affected zone, small thermal deformation, small thermal stress, and will not affect internal electrical properties. Especially the cold processing of 532m and 266m laser is suitable for precision processing of special materials. Fiber laser marking machine is mainly suitable for metal materials and most non-metal materials, such as iron, copper, aluminum, gold, silver and other metals and various alloys, as well as ABS materials, ink coatings, epoxy resins, etc.
Ultraviolet laser marking machine is mainly suitable for marking the surface of glass, polymer materials and other objects, microhole processing, flexible PCB board, LCD, TFT marking, scribing and cutting, etc., metal or non-metallic coating removal, silicon wafer micro Hole, blind hole processing, etc. co2 laser marking machine is mainly suitable for non-metallic materials, such as wood, paper, acrylic, glass and so on. There are also some materials that are suitable for both types of laser marking machines, but the marking process effect will be different. According to the actual needs of different users, it is equipped with different shapes and structures, fixtures and tooling, and tailor-made software systems to form a complete laser marking solution.
