Laser marking is a kind of marking method that uses high energy density laser to locally irradiate the workpiece to make the surface material vaporise or undergo a chemical reaction of colour change, thus leaving a permanent mark. Laser marking has no contact, no cutting force, small thermal impact, green and pollution-free processing technology and other advantages, especially suitable for high-precision requirements of the industry. Its processing mode is flexible, not only suitable for small batch multi-species operation, but also can meet the requirements of industrialised mass production, and customised laser marking machine can be combined with MES system technology, to play a variety of text, symbols, patterns, to adapt to the needs of the modern production of fast-paced. In addition, the laser marking machine on the material adaptability of a wide range of materials, can be in a variety of materials on the surface of the marking out of fine and durable marking.
Laser marking machine is a can be in a variety of material surface marking to form a permanent sign of a class of laser equipment.
1. According to the laser type (laser band) to points, laser marking machine can be divided into:
Fibre laser marking machine:
Fibre optic as a gain medium, the output laser wavelength is generally 1064nm, is near infrared light.
Suitable for marking a variety of metals and some non-metallic materials, with good beam quality, small size, low energy consumption, high stability, etc., widely used in electronics, automotive, aerospace and other fields.
CO₂ laser marking machine:
Adopting carbon dioxide gas as the working medium, the generated laser wavelength is 10.6μm, belonging to infrared light.
Mainly used for non-metallic materials marking, such as wood, paper, leather, plastic, organic glass, etc., in the food, medicine, daily chemical industry is widely used.
UV laser marking machine:
The laser wavelength produced is around 355nm, which belongs to ultraviolet light.
Focused spot is very small, can achieve ultra-fine marking, mainly used for marking materials with very high precision requirements, such as chips, liquid crystal screens, fine crafts, etc., in the semiconductor, electronic components manufacturing and other industries have important applications.
2. According to the working mode, laser marking machine can be divided into:
Continuous laser marking machine:
Laser beam continuous output, stable power, can achieve a large area, high efficiency marking.
Applicable to the marking speed and depth of high requirements of the occasion, such as large-scale production line product identification, large-area pattern engraving.
Pulsed laser marking machine:
The laser beam is output in the form of pulse, the energy of each pulse is high, which can instantly heat and vaporise the material in a short time.
The energy and action time of each pulse can be precisely controlled to achieve high-precision, high-quality marking, which is commonly used in occasions with high requirements for marking accuracy, such as jewellery, electronic product shells, etc.
Laser marking is extremely accurate, with precision down to the micron.The focused laser beam enables intricate designs, small characters and fine markings to be achieved with the smallest margin of error, making it ideal for applications requiring high precision.
Of course, Udibo's customised laser marking machines can be integrated into many automated production lines to increase productivity.Combined with production line MES systems to improve accuracy, fast processing and reliability, this increases the overall efficiency of the manufacturing process.Our company has integrated laser marking machines into a variety of manufacturing lines, including some of the largest companies in the automotive, consumer electronics and other manufacturing sectors.
Yes, Udibo Industrial Equipment Ltd. laser marking machines are usually suitable for high volume production.Its marking speed is fast, can quickly mark products; high degree of automation, can be integrated with the production line; good stability and reliability, maintenance is simple; marking quality consistency; and applicable to a wide range of materials to meet a variety of product needs, can be in the same production line for different materials product marking, to improve the production flexibility and efficiency.
Selecting the right laser marking machine for you requires consideration of a number of factors, including application requirements, equipment performance, brand reputation and after-sales service, budgetary considerations, and field trials. Here are some key points:
1. The first is to choose the type of laser marking machine with a cost-effective light source according to the material to be marked:
CO2 laser marking machine: laser wavelength of 10.64μm, belonging to the infrared light band. Applicable to the vast majority of non-metallic materials and some metal products engraving, such as plastic, glass, ceramics, leather, paper, wood, etc..
Fibre laser marking machine: the laser wavelength is 1064nm, which is near infrared light. Applicable to the vast majority of metal materials and some non-metallic materials engraving, including stainless steel, carbon steel, aluminium alloy, copper, iron and other metals, as well as engineering plastics and other parts of the opaque non-metallic materials.
Ultraviolet laser marking machine: belongs to the cold light source, the laser wavelength is 355nm, belongs to the ultraviolet wavelength. Can clearly mark heat-sensitive materials such as plastics, ceramics and other materials, especially suitable for food, pharmaceutical packaging materials marking, playing microporous, high-speed division of glass materials and silicon wafers for complex graphic cuts and other applications, but also for iPhone, cosmetics, pharmaceuticals, food and other polymer materials such as packaging bottles marked on the surface, can also be used for flexible PCB board marking, scribing, as well as silicon wafers It can also be used for flexible PCB board marking and scribing, as well as silicon wafer microvia and blind hole processing, etc. Suitable for fine marking and colour marking
2. Application requirements and equipment performance:
Define the application areas and specific needs, such as marking materials, marking content, marking size, laser power, scanning speed, cooling system, whether handheld or combined with automated production lines, etc., to choose different specifications of the laser marking machine.
3. budget considerations: according to your product category and budget range, choose the more cost-effective equipment. Usually the higher the power of the type of laser source equipment, the higher the price, the same power of the same type of laser marking equipment with different light sources, CO2 and fibre laser marking machine is cheaper, the ultraviolet laser light source laser marking machine is expensive, but the most versatile, usually known as the omnipotent light, if the product category is more (metal and non-metal are there, then), the choice of the ultraviolet laser marking machine is also a good choice!
