Direct Part Marking in the Medical Industry

Medical instruments undergo different types of laser marking according to their purpose.

Plastic medical instruments use different colored resins for easier visual identification. UV laser markers are optimized for a wide variety of resins, making them the ideal laser markers for these applications.

Metal medical instruments require traceability markings to ensure their sterilization process and the number of uses is strictly followed. As a result, laser markers are commonly used.

Reduced lead time, manufacturing costs, and environmental impact

Software Setup

  • Reduce manufacturing costs by creating custom programs that adjust for design and part changes.
  • Laser marking creates permanent, high-contrast marks without the use of ink.
  • Marking can be performed during the manufacturing process, which eliminates the need for extra machinery and additional processing time.

Complex Part Marking

3-Axis Marking

With KEYENCE's Z-MAP Creator software, 3D CAD data (STL format) can be imported directly into the Marking Builder software. The data can then be used as a foundation for three-dimensional marking. Characters and logos can easily be marked on even the most complex shapes with just the touch of a button. Because of its ease-of-use and high functionality, Z-MAP Creator has become an essential tool in surgical device manufacturing.

Direct Marking on Steel Medical Instruments

High-Speed, Precise Marking

Laser markers are used to create identifying marks (like 2D codes) on surgical equipment. These marks are highly visible, don't wear off and can't be erased by chemicals (which is a common problem with pad printers).

[RELATED APPLICATION] Laser marking part/lot numbers on medical tube connectors

Laser markers can mark both metals and plastics, and they're commonly used to create identifying marks on polycarbonate medical tubing. This identification process is typically accomplished with labels, but they are expensive, take time to produce and run the risk of falling off or being removed. Laser marking eliminates those risks and the costs associated with each.

Expiration Date & Serial Numbers on Transfusion Bags

Permanent, sharp markings

Laser marking intravenous bags creates a permanent, easy-to-read mark. Date codes and serial numbers are common marking examples. Ink printing (which is a common marking alternative) easily wears off and heat stamping is not clearly legible.
Replacing either system with a laser solves both issues and eliminates the costs associated with maintenance and consumables.

[RELATED APPLICATION] Laser processing on the surface of catheters

Laser markers can also be used on catheters and hypodermic needles. Cut locations and dwelling positions can be marked in the fluoride coating.
Ink systems are commonly used to create these marks, but there's a risk the ink will contaminate the product. Laser markers remove this risk since no chemicals are used in the marking process.
