Experience the American Bright Works Advantage
Laser marking, also referred to as part marking, laser etching, or engraving has become increasingly popular in the medical manufacturing community. It is an important application for product identification and traceability on many implantable and non-implantable medical components. Many kinds of metals and metal alloys can be laser marked including various stainless steel alloys, titanium and aluminum alloys, along with a variety of plastics and other non-metallics such as ceramics, glass, wood and leather.
Laser marking can be used for removal or engraving of a variety of metals. During removal, a thin outer coat can be removed using a laser light on anodized titanium or aluminum parts. The outer material is evaporated by the laser beam exposing the sub-layer material. For engraving, more material is removed to create a tangible impression on the surface, similar to mechanical engraving.
Laser marking can be used to identify parts with:
- Part numbers
- Lot numbers
- Part sizes
- Company logos and graphics
- And more
American Bright Works has the following two types of laser markers:
American Bright Works uses the Trumpf Trumark 5000, a YAG laser, for laser marking. This laser relies on an X-Y table where the workpiece or surface of the parts is typically stationary and the laser optics move in X and Y directions, directing the laser beam to draw vectors. We also have a rotary axis device which allows us to laser mark on curved surfaces for banding applications and for laser marking on diameter surfaces.
We also use the Beamer FB20 by Ultra-Dex, a fiber laser marking system, in many applications. This laser marker works by focusing a 1064 nm laser beam to the work piece via a flexible fiber cable. This allows the laser to be focused to a spot a few microns or less. With a pulse rep rate of up to 200 khz, we have found this type of laser marker to work well for marking both metallic and non-metallic parts.
Sound complicated? Perhaps it is, but what is most important are the results this process can create. Like every one of our other services, but in its own way, laser marking from American Bright Works is effective and attractive. Our state of the art, non-contact process ensures the highest quality possible. It is a computer driven process that ensures your last component will look as good as the first. Our laser marking process is a validated process.
If you have an application that might be a candidate for laser marking, contact us today and let us show you why our customers are some of the happiest customers in their fields for this type of service.
