With its ten business units, Schunk is broadly positioned and active in numerous industries, from automotive to electronics, life sciences, aerospace and logistics. For Pulsar Photonics, this offers a wide range of applications and opportunities for development projects within the Group, from which external customers can also benefit.

The commissioning of a new laser machine for Schunk Gerhard Carbon Technology (SGCT) marked the completion of the first Pulsar project within the Schunk Group at the end of October 2022. The company, based in Obernzenn, Franconia, is also part of Schunk - as a joint venture since 1996 - and has been developing solutions made of customized materials for the automotive, household and slip ring industries for more than fifty years. Specializing in laser-welded carbon springs, SGCT with its 60 employees mainly serves the automotive industry with about 170 million serial parts per year.

Against the backdrop of an ever faster growing order situation accompanied by the desire to produce a correspondingly larger volume of product faster, more cost-effectively and more effectively, contact was made with Pulsar Photonics. "The idea was initially to obtain a system that would give us added value in the areas of welding, cutting and - if possible - marking, in order to be able to respond more flexibly and at shorter notice to requests from the industry," explains Thorsten Graf, technology expert in applications engineering at SGCT.

The new system from Pulsar Photonics with built-in CW fiber laser from Aachen can perform the application laser cutting and laser welding using fixed optics in the development process of carbon springs for both flat planar parts and round bodies in a three-axis system. The machine with its large working area opens up the greatest possible travel paths and good accessibility while maintaining a compact design.
