Core requirements and application scenarios
1. High precision and permanent identification
Safety critical components: engine parts, gearbox housing, and brake system must be labeled with unique serial numbers (VIN associations), production batches, and material codes to meet the traceability requirements of IATF 16949 and global vehicle regulations (such as ISO 3830, FMVSS).
Environmental resistance: The label must withstand high temperatures (engine compartment 150 ℃), oil stains, vibrations, and chemical corrosion (such as immersion in antifreeze) to ensure readability throughout its entire lifecycle.

2. Full chain traceability and anti-counterfeiting
By using laser encrypted QR codes or dynamic codes to associate parts with the vehicle VIN code, it supports the full process traceability from raw materials to scrap recycling (such as shortening the recall and positioning time of defective parts to 1 hour).
Prevent the circulation of counterfeit accessories (such as filter cartridges and brake pads), with a counterfeit identification rate of over 99.5%.

3. Efficient and flexible production adaptation
Adapt to multiple materials (metal, plastic, rubber) and complex production lines (high dust environment in welding and painting workshops), support mixed line production (such as co production of new energy batteries and fuel vehicle components).
