Black Laser Marking | Ideal for Medical Products<\/h1>\n\n\n\n

<\/p>\n\n\n\n

Permanent, Corrosion-Resistant Black Laser Marking Ideal for Medical Technology<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Achieve high-contrast, FDA-compliant UDI codes on medical devices and other components using ultrashort pulse lasers \u2013 without compromising material integrity or using harsh chemicals.
<\/p>\n\n\n\n


Meet the Requirements of the Medical Field<\/h2>\n\n\n\n

Many industries need reliable and efficient processes that deliver high-quality results, but perhaps none more so than the medical equipment field. Between handling compliance needs, maintaining patient safety, and avoiding faulty parts and marks, medical device production facilities have a lot to juggle, and black laser marking is the ideal solution<\/a> for these concerns.
<\/p>\n\n\n\n

The Challenges of Sterilization and UDI Compliance
<\/h3>\n\n\n\n

Because of their use in patient care, medical devices need to undergo aggressive cleaning cycles to ensure sterilization. These cleaning cycles often feature high temperatures, harsh chemicals, and ultrasonic baths which, over time, can significantly wear down inkjet markings and traditional thermal laser markings created via annealing. This is because oxides are created that can eventually fade during repeated autoclaving and passivation.<\/p>\n\n\n\n

Meanwhile, the FDA\u2019s regulations and the EU\u2019s medical device regulations (MDR) stipulate that permanently legible labels with unique device identification (UDI) codes must accompany certain medical items for the product\u2019s entire lifecycle.<\/p>\n\n\n\n

So medical device companies<\/a> and medical facilities that want to maintain compliance need an effective solution that will endure cleaning cycles and maintain full legibility \u2013 enter black laser marking.<\/p>\n\n\n\n

Cold Black Marking with Ultrashort Pulse Lasers<\/h2>\n\n\n\n

Black laser marking uses ultrashort pulse lasers, or USPL<\/a>, operating in the range of picoseconds (one trillionth of a second) to femtoseconds (one quadrillionth of a second).<\/p>\n\n\n\n
