China's new energy vehicle industry is developing rapidly. According to the news released by the National Passenger Transport Federation, the sales of new energy passenger vehicles this year reached 74900, a year-on-year increase of 131.4%; According to the estimation of the China Automobile Industry Association, the sales volume of new energy vehicles in China is expected to reach 2 million by next year. Although the number of new energy vehicles is still dwarfed by the national car ownership, with the future trend of China's automotive technology development and increasingly strict fuel consumption and emission regulations, new energy vehicles will become an irreversible development trend.
 

After the "rapid development" period of new energy vehicles, it is foreseeable that advanced manufacturing technologies represented by laser technology will continuously promote the upgrading of the automotive manufacturing industry, while also promoting the rapid development of the laser industry itself. In particular, as one of the main applications in the automotive industry, laser cutting technology will have an increasingly broad application prospect.

Application of laser cutting in new energy vehicles

Laser cutting is a technology that uses a high power density laser beam to irradiate the material to be cut, quickly heating the material to the vaporization temperature, and evaporating to form holes. As the beam moves towards the material, the holes continuously form narrow slits, completing the cutting of the material. This cutting technology not only significantly reduces labor costs, but also can meet the increasing personalized needs of users. Currently, it is mainly used for planar plate cutting and three-dimensional cutting of automobiles. Among them, panel cutting is widely used, covering various aspects such as automobile parts, automobile body, automobile door frame, automobile trunk, automobile roof cover, etc.

Currently, in developed industrial countries such as Europe and the United States, 50% to 70% of automotive components are processed using laser processing. Some well-known companies have successively developed high-power, large-format, high-speed, flying optical path, three-dimensional, CNC automatic laser cutting machines. These laser cutting machines are used in various industries such as automobile manufacturing and aerospace, and new models are being introduced every year.

The laser industry in China started relatively late, but has developed rapidly. It has made up for the gap in the laser industry in China, and is striving to catch up with and catch up with the research and development of laser cutting technology.

Cutting Requirements for New Energy Electric Vehicles

The key technologies for the future development of new energy electric vehicles are the safety, cost, and energy storage capacity of power batteries. However, the manufacturing process of power batteries is complex and requires high safety, so the requirements for laser cutting and welding processes are also higher.

In addition to precise operation of the new energy battery part, production processes such as the vehicle body, steering system, and braking system also have strict requirements for the stability and flexibility of processing equipment.

Advantages of laser cutting

Advantages of laser cutting machines in new energy vehicles Laser cutting has the advantages of no wear on cutting tools, flexible cutting shapes, controllable edge quality, high accuracy, and low operating costs. It is conducive to reducing manufacturing costs, improving production efficiency, and greatly shortening the die cutting cycle of new products. Laser cutting has become the industry standard for new energy.

In addition, before the advent of laser technology, traditional machinery was commonly used in the power battery industry for cutting processing. However, during the use of cutting machines, wear, dust, and burrs fell off, causing risks such as overheating, short circuits, and explosions in the battery. Traditional cutting technologies have problems such as rapid mold loss, long switching times, poor flexibility, and low production efficiency. The innovation of laser processing technology plays a prominent role in the production of power batteries. Compared with traditional mechanical cutting, it has the advantages of no wear on cutting tools, flexible cutting shapes, controllable edge quality, high accuracy, and low operating costs. It is beneficial to reduce manufacturing costs, improve production efficiency, and shorten the die cutting cycle of new products.

Nowadays, the combination of advanced laser manufacturing technology and automobile production has become an inevitable trend. However, in the "eve" of the explosion of new energy vehicles, laser cutting has broad application prospects in the automotive industry and huge market potential. Laser cutting manufacturers should seize this rare opportunity to achieve a take-off in development.
