emdt.co.uk European Medical Device Technology Summer 2015 | 31 marketplace In Focus Lasers Laser-based plastics welder The laser-welding of plastics by means of the PowerWeld 2000 is a hygienic, economical and safe joining method for producing medical device components. Manufactured by LPKF Laser & Electronics AG, this machine accommodates all of the quality assurance measures that are required by the medical device industry. Depending on the model, this stand-alone system can be used in small-batch, medium-range and large-scale serial production. A variety of available laser sources and handling options enable it to be adapted to specified manufacturing conditions. LPKF Laser & Electronics AG Garbsen, Germany +49 5131 709 50 www.lpkf.de Laser-micromachining centres The laser-micromachining technology specialist GFH GmbH manufactures laser- based machining centres that feature the variable CL.control laser-pulse controller for ensuring precise component contours even at high processing speeds. The tight drilling tolerances, reproducible surface characteristics and precise cutting edges that medical instruments and implantable devices require can be achieved with these machines, the system controller adapting laser-pulse frequency to the process speed. This yields a processing technique that does not compromise the plastic, metallic or alloy workpiece material at rapid stock removal rates. Short and ultrashort laser pulses allow machining in microscopic dimensions. When equipped with trepanning optics developed in-house to move the laser beam on a very precise circular path, a micromachining centre can machine fine bores with diameters of 10 to 400 µm. GFH GmbH Deggendorf, Germany +49 9912 909 20 www.gfh-gmbh.com Fibre-coupled diode laser The SF2500/10 fibre-coupled diode laser system for materials processing features output power of 2.5 kW at 980 nm. Manufactured by Dilas Industrial Laser Systems, the system is based on microchannel-cooled diode laser bars and has a compact footprint and convenient aiming beam. With a beam parameter product of 110 mm mrad, it delivers its 2.5 kW through a cladding-mode-free QBH-type high-power 1000-µm-core- diameter fibre with a numerical aperture of 0.22. This stand-alone fibre-coupled diode laser system includes a water- water heat exchanger and diode laser driver within the compact chassis. The manufacturer's standardised diode laser control unit provides for standardised external interfaces. Materials processing applications are surface treatment, including selective hardening; cladding; and high-power brazing. In addition, the system can be used in scientific research where large spot sizes and a uniform intensity profile are required. Dilas Industrial Laser Systems Mainz-Hechtsheim, Germany +49 6131 9226 400 www.dilas-ils.com Laser-marking workstations With the high-throughput M2000-R and M3000-R stations, FOBA Laser Marking + Engraving completes its M series of compact workstations for industrial laser material processing. These automated laser class 1 laser-marking workstations come with a programmable z-axis and have two-position rotary tables measuring 670 and 950 mm in diameter, respectively, for the efficient, ergonomic processing of variously sized geometrically complex workpieces and small and large batches of parts. Parts are loaded and unloaded at one position while a part is being laser-marked at the other. The robust turntable stations are intended to provide fail-safe high-quality marking of parts of any kind with speed and precision. Designed for both standing and seated work and adaptable to individual needs, they allow for stepless adjustment of the working height between 1844 mm and 2144 mm.
