In the area of automotive marking, although there are several types including mold casting, electronic corrosion marking, stickers, screen printing, laser cutting, and laser marking on the market, laser cutting and laser marking were born at the latest, but their unique advantages are gradually being recognized by more and more automobile manufacturers compared with traditional processing methods.
In today's automotive industry, we can see the use of lasers everywhere. It can be said that today's laser technology is changing the current automotive industry. At present, laser technology has laser marking, hardening, cutting and welding in the automotive field. Each process has different processing characteristics from the traditional ones, which make the current automobile industry promoted a lot in the process and quality.
Recently, with the introduction of laws and regulations on automobile safety, higher requirements have been placed on the uniqueness of the identity of automobiles and parts. The establishment of automobile and parts identities is the basis for achieving product quality traceability and recall. Because laser processing differs from traditional processing methods, laser processing is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a color change chemical reaction, thereby leaving a permanent mark. There is no need to touch the surface of the processed article, so any profiled surface material can be marked, and the workpiece will not be deformed and generate internal stresses. At the same time, laser processing is a fast, programmable process with a long-lasting process, which is generally not affected by the steps required in the production process, nor is it affected by the harsh field environment, and the marking is wear-resistant, and the production process is easy to automate. This is undoubtedly the best mark processing solution for the automotive industry that pursues efficiency and quality.
