Identification Marking on Medical Devices

identification marking on gas cylinders

SCHMIDT manufactures laser marking machines for medical device manufacturers to help meet their strict product identification, device serialization and traceability guidelines.

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 requirments help reduce medical errors and more quickly identify medical devices for documentation and in the case of recalls.

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.

Metals: Titanium, stainless steel, cobalt-chromium, tungsten, tantalum and other medical grade alloys


Polymers: Polycarbonate, PVC, PE, PP, PS, PET, PEEK, silicone, nylon and more


SCHMIDT manufactures both class I certified laser enclosures and class IV open environment laser workstations.

Our class I enclosures adhere to federal protective housing guidelines, are guaranteed light tight and do not emit any laser beam or radiation. These laser systems can be equipped with rotary devices and special part fixtures for added support during the marking cycle. Our class IV open environment lasers are great for marking a variety of part shapes and sizes without limitation. They offer a sped up marking process and easy integration.
