Application of laser in medical industry

    Medical products are a kind of products that have direct contact with people, and are closely related to people's health and life safety. The production standards of medical products are very strict, and key components need to be marked with permanent, traceable marks, through which information such as the production time, location, production lot number and manufacturer of the product can be found. Moreover, in the medical industry, great attention is paid to the safety and health of products, and the ultra-short pulse laser marking technology has the advantages of cold processing, low energy consumption, little damage, high accuracy, strict positioning in 3D space, smooth marking surface is not easy to breed bacteria, etc., which fully meets the requirements of the medical industry for medical product marking, and now laser marking technology has penetrated into the medical industry.

    In medical applications, the main disadvantage of printing is that printed marks are always susceptible to removal or alteration (especially if printed on paper labels). This means that after transportation, handling and storage, printed marks can become difficult to identify, and can be easily counterfeited by people with ulterior motives. Print quality is also limited, which can create problems if manufacturers try to squeeze more information into a small area. In particular, for pill printing, there is pressure on the product when it is printed flat, so it is difficult to apply to the increasingly popular "soft capsules".

    Laser marking is a marking method that uses a high energy density laser to locally irradiate the workpiece and vaporize the surface material, thereby leaving a permanent mark. At the same time, in the process of processing, there is no need to contact the surface of the processed goods, no mechanical extrusion and mechanical effects, no cutting force, small thermal impact, to ensure the original accuracy of medical products. At the same time, it has a wide range of application, and can mark the vast majority of metal materials and non-metals, and the marking is durable and not easy to wear, which greatly meets the needs of the special marking of medical product materials. Compared with the traditional medical marking method, laser marking technology is not only more flexible in operation, but also has higher reliability and greater space for creation.
