Laser marking Yangcheng Lake hairy crab anti-counterfeiting logo

Yangcheng Lake hairy crab, also known as golden claw crab, is produced in Yangcheng Lake, Suzhou. It is popular among the public because of its multivitamins, delicious and sweet taste.

Since the Yangcheng Lake hairy crab production region has two different administrative areas, it has two industry associations, the Suzhou Association and the Kunshan Bacheng Town Association. These two associations respectively awarded the farmers under their administration with authentic Yangcheng Lake hairy crab anti-counterfeiting ring - the authentic Yangcheng Lake hairy crab ID card. Each crab has a unique code and certificate.

In order to prevent mixing the fictitious with the genuine, this year the Yangcheng Lake hairy crabs use laser marking technology to mark the number and security code on the crab shell. Consumers can directly scan the QR code of the hairy crabs to check the seedlings, feeding, breeding, lake areas of the crabs and other information.

The hairy crab Laser marking machine uses co2 gas to charge the discharge tube as a medium for generating laser light. When a high voltage is applied to the electrode and a glow discharge is generated in the discharge tube, this makes the gas molecules release the laser light. The laser energy is amplified to form a laser beam for processing the material. The laser beam path is changed by a computer controlled galvanometer to achieve automatic marking.

The text pattern information marked by Shenzhen Sunlasers co2 laser marking machine is exquisite and permanent, the marking is beautiful with high precision, which can greatly improve the product grade. The laser marking speed is fast with high yield rate, low consumables, no pollution, energy saving and environmental protection.
