Laser cutting technology can replace traditional mechanical knives with invisible beams, which has the characteristics of high precision, fast cutting, no limitations on cutting patterns, automatic typesetting to save building materials, smooth cutting, and low cost for processing enterprises. It will gradually develop, improve or replace traditional metal cutting production equipment.

1. The market space for laser applications in new energy vehicles is vast
In recent years, with the rapid development of the new energy vehicle industry, market demand has continued to expand and production capacity has been continuously improved. The manufacturing technology represented by laser technology has also promoted the upgrading of the automotive manufacturing industry, covering almost all application areas of the automotive manufacturing industry. At present, scientific and technological developments such as laser cutting, laser welding, and laser radar have been applied differently in various important aspects of China's new energy vehicle production and manufacturing. The penetration and application rate of lasers in the field of new energy vehicles are also being studied and continuously improved. Among them, laser cutting is one of the main laser applications in the field of new energy vehicle manufacturing. Laser cutting technology includes both flat plate laser cutting and three-dimensional space laser cutting, covering various management aspects such as Chinese automotive parts, car bodies, car door frames, car trunks, and car roof cover manufacturing. The application of 3D laser cutting technology in the automotive manufacturing industry is mainly in the design and manufacturing of car bodies, widely used in the development of new car models, production of deformed cars, cutting samples of automotive parts, cutting holes and edges of car body coverings, etc.


The development of laser welding technology is the fastest growing track in the application economy of the new energy vehicle industry. Laser welding technology is mainly applied to automotive coverings, power batteries, PACK modules, etc. For example, Tesla's groundbreaking 4680 cylindrical battery enables us to use innovative educational technologies such as large battery cells and full pole ears. And battery companies need to use laser welding for all pole ears, which brings laser welding equipment to a broader market.


In addition, as China's new energy vehicle companies accelerate their shift towards intelligence, the penetration rate of LiDAR in new cars continues to learn and improve, and it is expected that it will become a mainstream technology application in China in the future. Lidar combines optical, electronic, mechanical, software, chip, equipment and other technologies to help cars sense the road environment, autonomously plan driving routes, and control vehicles to achieve predetermined goals.


2. 3D laser cutting drives industrial upgrading. Currently, China's laser cutting technology is very mature and widely used in various industries.
Cutting can be divided into flat cutting and three-dimensional cutting. In industrial manufacturing enterprises, three-dimensional laser cutting is the trend of intelligent laser processing. It combines the latest fiber laser information technology and various six axis or seven axis robot control technologies in China to achieve high-speed and high-precision cutting or welding in three-dimensional network space economy. In many industrialized countries in Europe and America, most parts are processed using 3D laser processing technology. In the past, 3D laser processing technology equipment could have been monopolized by foreign manufacturers. Although the quality of enterprise products and services was excellent, the high sales market prices and post maintenance social costs always deterred domestic manufacturers.

3. Analysis of the application solution of laser cutting machine in automotive lightweighting


Laser processing covers all data application research fields of enterprises in the automotive manufacturing technology industry. Laser cutting is one of the main laser application problems. Laser cutting in the automotive service industry includes plane plate cutting and three-dimensional cutting. Laser cutting applications include automotive parts. Car body, car door frame, car trunk, car roof and other aspects. Currently, 50% -70% of automotive components are processed using lasers. 3.1. The application advantages of flat laser cutting machines in automotive lightweighting.


The cutting volume of sheet metal in the automotive industry is very large, and the advantages are also very obvious. In terms of cost, the cost of laser cutting is 60% of traditional cutting. For example, replacing traditional mold cutting with laser cutting can save a lot of mold manufacturing costs. Laser cutting machines are more flexible and meet the personalized cutting market needs of enterprises, saving work time and delivery cycles when cutting medium and small batches of boards with significant impact on area and complex contour shapes.


Laser cutting machines can accurately cut complex shapes through computer control systems, with easy modification and small errors. Laser cutting technology has a large processing area and can achieve whole board nesting cutting, which traditional cutting processes cannot easily achieve. Laser cutting has high precision and better surface flatness than traditional mechanical cutting. 3.2. The application advantages of 3D cutting (bevel cutting) of laser cutting machine in automotive lightweighting. Compared with other cutting methods, 3D laser cutting technology also has the advantages of high flexibility, high efficiency, good accuracy, low pollution, low labor relationship intensity, and resource cost savings for enterprises. Traditional cutting flexibility is not enough. A set of molds can only target one workpiece and one process. 3D laser cutting has high flexibility and can cut any workpiece and any process.
