Development status of laser processing segment industry
1. Laser marking equipment industry
Laser marking is one of the important application fields of laser processing. It mainly uses high-energy density laser beam to perform shallow etching on the workpiece, so as to vaporize the surface material or produce color change reaction, so as to leave lasting engraving, or achieve the purpose of surface processing such as texture processing. With the decline of the price of laser marking equipment and the wide demand of the downstream market, China's laser marking equipment industry has ushered in a period of rapid development in recent years. With the expansion of the downstream application field of laser marking and the recovery of the prosperity of the downstream industry, the sales scale of laser marking equipment in 2020 has increased rapidly and exceeded the level in 2018.
As the localization of upstream CO2 laser and fiber laser market increases and the competition intensifies, the price of laser marking equipment decreases, and the cost decreases, which is conducive to the further expansion of downstream application fields; At the same time, with the development of 5g communication industry and the rapid development of new energy vehicles, the global consumer electronics, home furnishings, automotive industry, the Internet of things and other industries will further release the demand for laser marking equipment, and the penetration rate of laser marking equipment in many industries will increase.
2. Laser cutting equipment industry
Laser cutting uses the laser beam output by the laser oscillator to focus through the focusing lens to generate a highly focused and high-energy laser beam to irradiate the material to melt and evaporate, and then uses oxygen and other auxiliary gases to blow away the excess slag in the laser cutting seam and generate high heat, so as to achieve the purpose of cutting the material. Due to the large energy per unit area, laser can cut high-precision products with small slits.
In China, laser cutting equipment is widely used in terminal industries, including machinery, automobile, furniture and household appliances, electronic product screens and other fields. With the improvement of localization rate of high-power lasers in China, the downstream market demand is rapidly released, and the shipment quantity of laser cutting equipment shows a rapid growth trend.
3. Laser welding equipment industry
As a modern welding technology, laser welding has the advantages of deep penetration, fast speed, small deformation, low requirements for welding environment, high power density, free from the influence of magnetic field, not limited to conductive materials, working conditions without vacuum, and no X-ray during welding. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts, and is widely used in automobiles, ships Aerospace and other high-end precision manufacturing fields.
Development prospect forecast of laser processing industry
The main development trends of the laser industry in the future are: ultrafast laser will become the future development trend of the laser industry, the industry will continue to develop in the direction of high precision, and the industry will continue to develop in the direction of flexibility.
As the brain of laser processing equipment, with the continuous development of laser processing equipment, the performance requirements of laser processing control system are increasing day by day. In the future, the application of laser processing control system will develop in the direction of high precision.
With the technological development and cost reduction of picosecond, femtosecond and other ultrafast lasers, ultrafast laser processing will gradually replace the traditional processing technology and be used for the processing of brittle materials. It is expected that ultrafast laser processing will become the main processing method for OLED screens, LCD screens and high-end glass covers.
The laser processing control system continues to develop in the direction of flexibility. In order to adapt to the personalized needs of downstream users for products, respond to changes in the supply chain in a timely manner, and achieve consumer oriented flexible processing, the laser processing equipment needs to have multi-function and high adaptability, the ability to process different raw materials with product changes, and the ability to determine the corresponding process flow with different processing objects The ability to expand system modules as new requirements arise.
