Medical Device Part Marking


In order to meet industry standards, medical devices must be marked or engraved to provide a reliable and readable ID number for each part. GT SCHMIDT manufactures laser marking machines for medical device manufacturers to help meet their strict product identification, device serialization, and traceability guidelines. GT Schmidt takes up the various challenges and multifaceted requirements and develop reliable solutions for medical device marking. We understand the importance of not only ensuring the proper marking of all medical products but also the capability of improving medical device safety and regulations.


The FDA requires medical device manufacturers to have a unique device identifier also known as UDI. Beyond labeling their products, some medical devices like surgical equipment, implantables, life-supporting devices, and life-sustaining devices are required to bear a permanent direct product marking. These devices require both a unique device identifier and production identifiers (expiration dates, serial numbers, lot, and batch numbers). These unique identifiers are required so the medical devices can be traced from the time they were manufactured, through their distribution, on to final use. These strict requirements help reduce medical errors and more quickly identify medical devices for documentation and in the case of recalls.

GT SCHMIDT manufactures lasers markers for laser annealing on non-ferrous high grade metals, and for high contrast marks on plastics without using any solvents or additives. The lasers produce a low local heat that changes the color of the surface layer. The resulting mark is permanent and the surface of the material remains intact eliminating grooves and the potential for bacteria to grow. Laser marks done with the annealing process are corrosion resistant and can withstand many sterilization processes such as passivation, centrifuging, and autoclaving.
