Laserline at Coiltech 2025: Laser systems for copper material processing
At Coiltech 2025 in Augsburg, laser specialist Laserline will be showcasing solutions for challenges in the field of copper material processing, such as contacting copper wire windings in electric motors, additive manufacturing of electronic components and recycling-oriented separation of soldered joints.
Laser solutions for the production and recycling of copper-based electronic components - this is the focus of Laserline's presentation at Coiltech Deutschland 2025 (March 26-27 in Augsburg, booth 5-H22). The industrial laser specialist will also be providing information about the wide range of options for copper material processing using blue diode lasers. For electrical contacting - for example of electric motor coils - Laserline will be presenting system solutions for preparatory stripping in the joining area (wire stripping) and subsequent laser welding of the contacts (wire/poles connection). Both solutions are based on blue diode lasers with a wavelength of around 445 nm and are supported by high-precision beam shaping optics. The excellent absorption of blue laser radiation in copper in these system configurations enables even very fine wires to be processed effectively and gently.
Laser systems for the production and recycling of copper-based electronic components
The new blue high-brilliance lasers with WBC technology will be presented at the trade fair stand as a further manufacturing option for electronic components. With a beam quality of ≤ 4 mm∙mrad and output powers of 400 and 800 watts, the LDFblue 400-wbc and LDFblue 800-wbc diode lasers enable the additive manufacturing of copper-based electronic components using laser powder bed fusion in robust and spatter-free processes. They combine exceptional beam quality with a robust and industrially proven system architecture. With blue diode lasers in combination with flexibly adjustable OTZ zoom optics, Laserline will also be showing system configurations for the heat-based separation of soldered copper connections, as can be used for the recycling of copper busbars or other copper-based electronic components. The trade fair appearance will be rounded off by a presentation entitled "Blue Diode Lasers: A Multitool for Processing of Copper". Dr.-Ing. Luisa-Marie Schäfer-Heine, product expert for blue diode lasers at Laserline, will provide information on the many possible applications of blue diode lasers in industrial copper material processing.
