Since the Food & Drug Administration (FDA) announced the upcoming implementation of obligatory Unique Device Identification (UDI) marking for medical devices, manufacturers have been searching for feasible and economic marking solutions. Read More
Following the Unique Device Identification directive (UDI), mandated by the Food & Drug Administration (FDA), medical devices have to be clearly identified to ensure traceability and patient safety. The rule-compliant implementation challenges medical device manufacturers and raises many questions. Read More
Depending on the material and application of the product, plastic cables or tubes can be marked with a UV or a fiber laser. UV is for plastics like silicone, that must not be impacted by too much laser heat due to its surface structure. Fiber is an appropriate laser method for plastics like Nylon which is often disposed to environmental strain. Read More
Well, you might expect from a person with my background that there is only one possible answer. However, I believe that the appropriate answer is: It really depends.
Laser paint removal is the most advanced way of creating highly precise sharply contoured symbols on coated, translucent or transparent plastics. Day-night-design components carry signs that are backlit by night and safely distinguishable in any lighting conditions. These components are usually made of white ABS-plastic, like this automotive center console (see picture in the middle).
Anticipating the upcoming football world championship, we are well prepared: Drinking glasses and snack dishes have been marked appropriately! Our application engineers chose UV-laser marking systems for glass and wood application. High precision marks and only minimal heat impact on the surrounding structures can be achieved.
At the Medtech Europe, starting tomorrow in Stuttgart, FOBA will demonstrate laser marking on medical forceps. Visitors can get this trade show sample and see in live demonstrations, how vision-based automated laser positioning enables accurate marking results, even on products that are totally out of alignment from their expected positions.
For sample marking on ball bearings, we applied marks with two different procedures for demonstration purposes: laser engraving on the outside, laser annealing on the inside circle. Both markings are robust and durable. For heavily used metal substrates like some bearings, the preferred marking method is often laser engraving, because the marking remains readable even in highly abrasive use.
Musical instruments often get marked with company logos, serial numbers or other information. Different marking systems are utilized, depending on the material.
Expensive materials like titanium, and especially the products made from it, require markings of an appropriate high quality. In order to demonstrate the marking capabilities of a pulsed fiber laser on titanium, we have marked the material with 80 fields of different colors on plates of 5 x 5 cm (1.97 in²) for our sample case. By specifically adapting the laser parameters, it is possible to obtain multiple shades and intensities of colors.
