The medical industry has been using laser technology to mark medical devices for many years. The reliability and durability of laser marking has brought great benefits to medical device companies. However, there is still room for laser marking and engraving to improve and help the medical industry to carry out quality control and increase product production.
I write these high-demand application reports can be compared to going to the kitchen when you are hungry: the food in the kitchen smells very appetizing, but once you really have to touch the jar, you will be criticized; The attraction of those foods is still there, even stronger, but the basic needs are not met. The application of laser material processing in the medical industry is similar: there are many exciting applications and dazzling innovations, but they cannot reveal detailed information and provide exemplary images, and confidentiality agreements prevent people from sticking their noses more. Go into the jar. Nevertheless, this paper attempts to outline the machining process as well as innovative developments.
Classic application
Until recently, the classic application of laser marking in the medical industry was still marking on stainless steel surgical and dental equipment. These marks are easier to read, and even the number of times of sterilization can be increased a hundred times. Importantly, it is marked on an absolutely smooth surface to prevent bacteria from sticking to the surface. After marking the surface can not damage the corrosion-resistant chemical passivation treatment, in order to make the anti-corrosion coating even after years of use and countless times of cleaning and disinfection, also has been there.
Ulrich Ofer, vice president of marketing and applications at FOBA, said: "After many experiments and tests in our own and external laboratories, the solutions introduced by the application development department now meet these strict requirements. Solutions suitable for surgical devices are also suitable for bone plates, bone screws, high-impact polystyrene and artificial joints. In addition to stainless steel, other materials suitable for treatment include titanium, silver and ceramics. In short, the problem can be boiled down to selecting the appropriate laser wavelength and specific laser parameters according to different materials."
