In recent years, with the expansion of global automotive market demand and the accelerating of automotive intelligentization, advanced manufacturing technologies represented by laser technology are constantly promoting the updating of the automotive industry. The combination of laser advanced manufacturing technology and automotive production is already the trend of the times.
Laser technology is widely used in the automotive industry, such as the use of lasers for the cutting and welding of various parts such as automotive sheets and transmission gears. It can also be used for some surface treatments such as surface hardening and surface alloying. Laser technology can also be used to accurately detect the length, density and size of precision components.
Laser cutting has been most frequently used in automotive manufacturing. Laser cutting has the advantages of high cutting edge quality, low heat input, fast processing speed, etc. It can be used for cutting difficult materials such as aluminum, aluminum alloy, carbon steel and stainless steel, so that new materials can be applied in automobile lightweighting.
Automotive parts and materials, including a variety of metals, such as airbag fabrics and composite materials used in automotive interiors, are more flexible and efficient with laser cutting. At the same time, the laser cutting adopts non-contact processing, which has almost no consumables and no pollutants. The laser cutting machine can also solve the problem of cutting and trimming of some metal molded parts.
Laser Surface Treatment
Laser surface treatment, by improving cost and quality while providing environmentally friendly processing, has replaced traditional processes in aerospace, automotive and heavy-duty manufacturing, such as sand blasting, dry ice blasting, wet chemical bath deposition and manual sanding.
Laser welding maximizes the use of laser characteristics. As a laser welding machine that replaces traditional welding technology, it has small welding material loss, small deformation of welded workpiece, high welding efficiency, high welding precision, stable equipment performance and automatic control. The system can be combined with a variety of operating platforms to achieve intelligent production processes, reduce manual operations, and reduce labor costs.
Laser welding can be applied to the welding of steel plates of different thicknesses and the precision welding of automobile parts, and the metal parts of the same or different thickness, strength, shape and size are welded into one unit. Automobile manufacturers will stamp such tailor welded blanks into specific spare parts according to different market demands. At the same time, they can reduce the production cost of automobiles, reduce the heavy tonnage of the whole vehicle, reduce the fuel consumption, and make great contribution to environmental protection.
Laser processing is a marking method that uses a high-energy-density laser to locally illuminate a workpiece to vaporize the surface material or cause a color change, thereby leaving a permanent mark, which does not need to touch the surface of the processed article, so it can be Any profiled surface material is marked and the workpiece does not deform and create internal stresses. This is undoubtedly the best marking processing solution for the automotive industry that pursues efficiency and quality.
The main applications of laser marking machines in the automotive industry include marking of automotive parts, engines, label papers (flexible labels), etc. Laser bar codes and QR codes are often used for traceability of automotive parts, which not only meets the vehicle recall system of defective vehicles. Requirements, but also the acquisition of parts information and quality traceability, which has important special significance for the current automotive industry.
