Raysource Laser Marking Brings a New "Quiet Deep Engraving" Experience to Automotive Manufacturing

In the automotive manufacturing process, marking the Vehicle Identification Number (VIN) on the cab frame is a critical procedure, as it relates to the vehicle’s identity and subsequent traceability. Although traditional pneumatic marking methods are fast, they come with pain points such as high noise, cumbersome operation, inconsistent marking depth, and poor user-friendliness for workers. These issues severely impact work efficiency and the production experience, making it an urgent problem to solve on automotive production lines.

A certain automotive manufacturer had been using pneumatic marking equipment, with a single marking time of about 18 seconds. However, the significant noise and vibration not only affected worker health and the workshop environment but also limited the flexibility of equipment layout. Just as the company was seeking a better solution, Raysource’s high-power laser marking machine arrived—quietly initiating an upgrade centered on "low noise, high-power deep engraving, and high efficiency."

The company’s explicit requirements for the new equipment were:

① Marking Speed: Can it achieve or even exceed the original efficiency of 18 seconds per piece?

② Marking Depth: Can it stably meet the 0.3mm depth standard?

③ Marking Area: Is the energy uniform within a 100×100mm range?

④ Equipment Stability: Can it adapt to high-intensity continuous operation and maintain a low failure rate?

⑤ Integration & Automation: Does it support automation integration and system connectivity?
