After entering the 21st century, in the automotive industry in Japan, the United States and Europe, people are increasingly concerned about maintaining their competitiveness in the market, especially their R & D capabilities. Small batch production and customized production have become a development direction. This production mode combines the advantages of manual manufacturing and mass production, and avoids the disadvantages of high cost of manual production and lack of flexibility of mass production.

Under this condition, manufacturers of laser processing equipment are required to constantly carry out technological innovation on their products and maintain their product competitiveness. In the design, they should not only pay attention to meeting the needs of current automotive panel processing applications, but also prepare for the future development of users, that is, to provide reasonable solutions in advance for the small batch production mode.

In recent years, users in the automotive body industry have shown a strong demand for the performance improvement of the equipment in the following three aspects - faster processing speed, larger processing range (especially the current very successful MPV, SUV, pickup truck) and flexibility, compact structure, concise operation and other characteristics, Huagong technology has specially made a brand-new design for its three-dimensional laser processing machine tool. It adopts a gantry frame structure, all moving parts are in the air, and the whole processing area is open to users, which has very good accessibility. Users can choose a variety of configuration schemes from manual to automatic according to the situation of their products. It has reached an unprecedented level in dynamic performance. At the same time, the integrated structural design not only makes the installation simple and rapid, but also has the function of rapid installation and rapid relocation between different production departments, just like the emerging lathes and grinders.

As people have higher and higher requirements for automobile comfort and safety, gradually increasing the body size, considering the use of four-wheel drive technology, and adding more electronic equipment have become more and more trends in the automotive industry, all of which will inevitably increase the weight of the whole vehicle and lead to the contradiction with the goal of reducing fuel consumption, The only solution is to reduce the weight of the body without affecting the performance. This can be verified by the wide use of internal hydroforming parts (Ihu) and high hard steel materials (warm formed steel) in the field of automotive body.

Internal high-pressure molding is to make the outer wall of hollow parts (mainly tubular parts) in the mold completely close to the mold through high-pressure emulsion (water and additives). The parts produced by this method have high forming accuracy and light weight, and can form multiple pipes that need to be welded at one time, reducing the number of welding and improving the overall strength. Its good strength to weight ratio and low production cost make it also widely used in body and chassis structures. Because the shape of internal high-pressure forming parts is very complex, and there are a certain number of holes and slots to be cut, it is impossible to use the traditional punching die, and three-dimensional laser cutting is one of the best solutions at present.

The high hard steel material (warm formed steel) has a very high internal tension (1500mpa/mm2), so the elastic deformation is very small, which is very suitable for the parts of the automobile body that require high strength, such as bumper bracket, front beam, side beam, stiffener and so on. Under the same strength requirements, the weight of high hard steel is much lighter than that of normal steel plate, and many welding procedures can be reduced. Therefore, the weight of the car body can be effectively reduced on the premise of ensuring safety. Because of this, the parts of this material can hardly be processed by the traditional punching die, and the only solution is three-dimensional laser cutting.

Three dimensional laser cutting machine overturns the punching and shearing process of stretched parts. From aerospace to automobile and civil machinery, from steel structure to automatic welding, from hardware to daily necessities... All kinds of stretch parts need to use three-dimensional laser cutting machine process, which is a good proof that it is widely concerned by the industry and can develop rapidly. Because of its high precision, high speed, high flexibility and other characteristics, it effectively solves the "pain points" of 3D modeling. Three dimensional laser cutting machine will lead the manufacturing industry from plane based bending, cutting and welding process to three-dimensional modeling. One time molding, reduce process, reduce cost, improve performance, beautiful and practical.

As far as the automobile manufacturing industry is concerned, the application of laser cutting technology has driven the industrial upgrading. In terms of the whole manufacturing industry, laser cutting technology drives Chinese manufacturing towards globalization and intelligence. With the transfer of the global manufacturing center to China, the demand for laser cutting machines in China is also growing. The laser cutting industry has begun to take shape from scratch. Laser cutting machine not only has unlimited market potential in automobile manufacturing, but also shows amazing explosive force in other application fields.
