Why does the automotive industry need laser processing?

In Japan, the United States and Europe, where the automobile industry is relatively developed, people are paying more and more attention to maintaining their market competitiveness, especially R&D capabilities. Small batch production and customized production have become the development direction. This production method combines the advantages of manual production and mass production, and avoids the disadvantages of high manual production costs and lack of flexibility in mass production.

In this case, manufacturers of laser processing equipment must continue to innovate their products and remain competitive. In the design, they should not only pay attention to meeting the current automotive board processing and application needs, but also prepare for the future development of users, that is, provide solutions in advance. Small batch production is reasonable. In recent years, users in the body industry have shown strong requirements for the following three aspects of equipment performance: faster processing speed and wider processing range (especially MPV, SUV). In this regard, successful pickup trucks have more demands. An industrial company with flexibility, compact structure and simple operation characteristics focuses on its flagship product. A new laser treatment machine was designed. It adopts a gantry structure, all moving parts are in the air, and the entire processing area is open to users and easy to access. Users can choose different layout designs from manual to automatic according to the product. At the same time, the integrated structural design not only makes the installation simple and quick, but also has the functions of rapid installation and rapid migration between different production departments, just like the emerging lathes and grinders.

As people have higher and higher requirements for car comfort and safety, by using four-wheel drive technology, larger and larger body sizes and more and more electronic devices have become more and more popular in the automotive industry. All these will inevitably increase the weight of the vehicle and lead to conflicts between the goals of reducing fuel consumption. The only solution is to increase the weight of the vehicle and reduce the weight of the body without affecting performance. The wide application of hot-formed steel in the car body field can prove this.

High-pressure internal mold molding involves the use of high-pressure emulsion (water and additives) to make the outer wall of the hollow part (mainly tubular) in the mold completely close to the mold. The parts produced by this process have high precision and light weight, and can form many pipes that need to be welded at the same time, reducing welding time and improving overall strength. Its good strength/weight ratio and low production cost make it widely used in body and chassis structures. Due to the complex shape of the internal high-pressure forming parts and the need to cut many holes and slots, traditional punching dies cannot be processed. Three-dimensional laser cutting is currently one of the best solutions.

High hardness steel (hot formed steel) has high internal tension (1500MPa/mm2), so its elastic deformation is very low. It is very suitable for body parts that require high strength, such as bumper brackets, front beams, side beams and stiffeners. Under the same strength requirements, the weight of high-hardness steel is much lighter than ordinary steel. Steel plates can reduce many welding procedures. Therefore, in order to ensure safety, the weight of the vehicle body can be effectively reduced. Therefore, part of this material is difficult to process with traditional molds, and the only solution is 3D laser cutting.
