Medical devices are commonly made of metal, plastic, glass, etc. However, as medical devices, they all have a unique device identification code, namely the UDI code, to track product information and improve traceability. How do we mark the UDI code on common medical products? Today, I will introduce a device that is widely used in the medical industry - the UV laser marking machine.
UV laser marking machine, also known as medical laser marking machine, is a high-precision laser marking equipment. For medical-grade plastics, the UDI mark must be smooth to the touch and have no obvious tactile sensation to prevent the growth of bacteria. Therefore, the difficulty of marking the UDI code is greatly increased. The traditional ink printing and dyeing process has been gradually abandoned due to hidden dangers. Laser marking technology has become the mainstream technology for marking medical supplies because it meets the process requirements.
For marking medical plastic products, we use UV marking machines with a "cold marking" effect. During the cold laser marking process, the use of UV lasers changes the molecular structure of the material, which is very friendly to heat-sensitive materials. The marking effect is very ideal. When white plastic strongly absorbs UV light, chemical changes occur in the plastic, making it darker. This process produces smooth, highly clear marks inside the plastic, not just on the surface. This is the characteristic that distinguishes UV laser marking machines from other types of marking machines.
