Traceability marking on hard to mark medical plastic MEDICAL UHMWPE (ultra-high molecular weight polyethylene) is a very important material in medical applications, like joint replacement. Serial and lot numbers are required in production: infrared lasers aren t effective because the surface of the material reacts irregularly. The marking has to be readable, permanent and non-dangerous for the human health. DLA s Green-Lase 10W @ 532 nm laser can effectively mark UHMWPE in human readable applications. Small bursts are produced by the laser spot, resulting in a nice visual effect. It is demonstrated that the marking process doesn t affect the mechanical properties (namely, the resistance to tensile stress) of the samples. A 160 mm f-theta lens covers up to 100 x 100 mm marking area. GreenLase 10W @ 532 nm F-theta = 160 mm Marking time: n. a.

Car window traceability using datamatrix codes AUTOMOTIVE The customer requested a laser marking solution able to grant effective traceability of car window glasses (floating glass) by using datamatrix codes. Perfect readability of the code through the entire production process (including temper), together with unaffected mechanical properties of the glass, are fundamental requirements. The customer asked us to find the best solution choosing among a CO 2 laser, a green laser and an UV laser. The maximum amount of marking time was 5 seconds. DLA s UV-Lase was found to be the best marking solution to meet the customer requirements. Unlike infrared and green light, UV light marks the datamatrix inside the glass, thus making it permanent through all the following treatments. Moreover, the glass does not lose its mechanical characteristics (e.g. resistance to tensile stress). UV-Lase 3 W @ 355 nm F-theta = 100 mm marking time < 5 s 2D resolution: 12 mils, 7 mils, 4 mils

Glass Substrate Traceability on Solar Cells SOLAR Traceability through datamatrix codes, alphanumerical codes, or both, is highly recommended in solar cells glass substrate production. But laser marking on one side of the panel might affect also its opposite side, where a very thin TIN coating is applied. Thus accurate and selective laser marking is required. When DLA s UV-Lase laser marker is adjusted to focus on the uncoated side, there is no effect on the opposite side of the thin glass substrate. Since traceability marking requires small sizes, a marking speed between 50 mm/s and 150 mm/s provides high throughput, depending on fonts and graphics.
