Laser Marking in Automotive VIN Coding

The rapid development of laser technology has led to its widespread application in various industries, particularly in automotive manufacturing. Whether it's traditional fuel vehicles or new energy vehicles, every marking on a car body or component serves as a crucial identifier for tracking vehicle quality. Consequently, laser marking has become indispensable in the automotive manufacturing process.

Developed countries in Europe and America have already adopted laser processing for 80% of their automotive components. The popularity of laser technology can be attributed to its high energy density, low heat affected zone, fast marking speed, smooth surface finish, simple operation, intelligent control, and the ability to create permanent markings.

Laser marking excels in deep engraving of VIN codes on car bodies, seat beams, engine cylinder heads, and other components. Key advantages of laser marking in automotive applications include:

· Continuous and pulsed modes: Offers flexibility for various marking tasks.

· High peak power: Up to 3000W for efficient and precise marking.

· Excellent output stability: Ensures consistent marking quality.

· Superior beam quality: Delivers fine and detailed markings.

· QBH output head with adjustable output length: Adapts to different marking requirements.

· Air or water cooling: Efficient heat dissipation for extended operation.

Beyond VIN coding on car bodies, seats, and engines, laser technology finds extensive applications in other automotive components, such as plastic automotive lights, airbag igniters, triggers, fuel injectors, air conditioners, cigarette lighters, steering gears, and sensors.

In summary, laser marking technology plays a pivotal role in the automotive industry, offering numerous benefits such as high precision, durability, and flexibility. As the automotive industry continues to evolve, laser marking will remain a critical technology for ensuring product quality and traceability.
